x = -4
Step-by-step explanation:
there is no y-intercept when slope is undefined
Undefined slope indicates a vertical line passing through the x-axis at the x-coordinate of any known point
A ball is tied to a string and swung in a horizontal circle with a tangential speed of 2.5 m/s. The length of the string is 1.5m. Calculate the ball’s centripetal acceleration.
Answer:
[tex]a_c=4.17\ m/s^2[/tex]
Step-by-step explanation:
Centripetal Acceleration
It's the acceleration of an object moving in a uniform circular motion that pushed the object toward the center.
Its magnitude can be calculated as follows:
[tex]\displaystyle a_c=\frac{v^2}{r}[/tex]
Where:
v = tangential speed
r = radius of the circle
The ball is tied to a string describing a circular motion with a radius of r=1.5 m. The tangential speed is v=2.5 m/s, thus the acceleration is:
[tex]\displaystyle a_c=\frac{2.5^2}{1.5}[/tex]
[tex]\displaystyle a_c=\frac{6.25}{1.5}[/tex]
[tex]\mathbf{a_c=4.17\ m/s^2}[/tex]

Answer:-2
Step-by-step explanation:
-y+2x=-1 needs to be changed to y=-2x-1 so that you can set the two equation equal to each other in order to solve for x. That makes it -2x-1=1/2x+4
-4= -4
-2x-5 = 1/2x
+2x = +2x
-5 = 2.5x

A triangle has side lengths of (1.3k+3.5m)(1.3k+3.5m) centimeters, (4.1k-1.6n)(4.1k−1.6n) centimeters, and (9.7n+4.4m)(9.7n+4.4m) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
(5.4k+7.9m+8.1n) centimeters
Step-by-step explanation:
Given the side length of a triangle;
S1 = (1.3k+3.5m) cm
S2 = (4.1k-1.6n) cm
S3 = (9.7n+4.4m) cm
Perimeter of the triangle = S1+S2 + S3
Perimeter of the triangle = (1.3k+3.5m) + (4.1k-1.6n) + (9.7n+4.4m)
Collect the like terms;
Perimeter of the triangle = 1.3k+4.1k+3.5m+4.4m-1.6n+9.7n
Perimeter of the triangle = 5.4k+7.9m+8.1n
Hence the expression that represents the perimeter of the triangle is (5.4k+7.9m+8.1n) centimeters
You manage an appliance store that currently has excess warehouse inventory. You decide to offer a price reduction on washer-dryer combination sets. As a result of the price reduction, the company sells 36 combination sets, and this reduces their inventory by 25%. How many washer-dryer combination sets are in the warehouse after the sale? 27 70 108 144 864
Answer:
108Step-by-step explanation:
Let the amount of washer-dryer combination sets that are in the warehouse after the sale be x
Initial amount in the ware house is y
y - 36 = 75% of y
y - 36 = 0.75y
0.75y - y = -36
-0.25y = -36
y = 36/0.25
y = 144
The initial amount of wash dryer before sale is 144
After sale the amount of set in the house x = 144 - 36 = 108
Hence there 108 washer-dryer combination sets are in the warehouse after the sale

An x-method chart shows the product a c at the top of x and b at the bottom of x. Above the chart is the expression a x squared + b x + c. Consider the trinomial 6x2 + 13x + 6. The value of ac is . The value of b is . The two numbers that have a product of ac and a sum of b are 4 and .
Answer:
1. ac = 36
2. b = 13
3. 4 and 9
Step-by-step explanation:
Given
6x² + 13x + 6
Required
Fill in the gaps
Solving (1): The value of AC
The general form of an equation is:
ax² + bx + c
By comparison:
a = 6
b = 13
c = 6
So,
ac = a * c
ac = 6 * 6
ac = 36
Solving (2): The value of b
In (1) above, we showed that
b = 13
Solving (3): Two numbers that satisfy product ac and sum b
We have that.
ac = 36
If one of the numbers is 4, then the other number is
Other number = 36/4
Other number = 9
Alternatively, we have that.
b = 13
If one of the numbers is 4, then the other number would be:
Other number = 13 - 4
Other number = 9
Answer:
ac = 36
b = 13
The two numbers that have a product of ac and a sum of b are 4 and 9

In 2018, researchers examined a random sample of 1455 "disadvantaged" Australian school children (children aged 6 – 15 from rural and outer suburban areas) and found that 4.3% of them were nearsighted. In 2014, the rate of nearsightedness among such children was 3.5%. Is this strong evidence that the parameter has changed since 2018?
Answer:
No, this is not a strong evidence that the parameter has changed since 2018. This is because, there are so many factors that could have led to the fall in percentage of "disadvantaged school students" from the initial 3.5% to 4.3%.
Some of the factors could be reduction in the number of disadvantaged students, sample size considered being considered as well as the geographic location upon which the random sampling was made.

Answer:
x = 5 22/24 OR x = 5 11/12
Step-by-step explanation:
x - 3/4 = 5 1/6
To solve this we mush use inverse operations
x - 3/4 + 3/4 = 5 1/6 + 3/4
x = 5 22/24
x = 5 11/12
To add the fractions there has to be a common denominator.
1/6 x 4/4 = 4/24
3/4 x 6/6 = 18/24
Keep denominators the same and add the numerators.
If your teacher wants the answer not simplified the answer is
x = 5 22/24
If your teacher wants it simplified the answer is
x = 5 11/12

Reese is selling lemonade at the parade. He gets to keep 50% of the money he collects. A large lemonade is $6.00 and a small lemonade is $2.00. The expression represents 50% of the money he collects. 0.50(6l + 2s) Use the Distributive Property to expand the expression. The simplified expression is
Answer:
3l + 1s
Step-by-step explanation:
Given that:
The expression to represent 50% of the money collected : 0.50(6l + 2s)
Expanding the expression :
0.50(6l + 2s)
(0.50 * 6l) + (0.50 * 2s)
3l + 1s
Hence, the simplified expression is 3l + 1s

The Marked price of an article is rupees 4500. After allowing some percent of discount and levying 10% VAT it is sold at 4400, find discount percentage
Answer:
given,
mp= 4500
now
discount amount=dis%of mp
=x%of 4500
=45x
now,
sp=mp- discount
=4500-45x
now,
vat=vat%of SP
=10%*4500-45x
=450-45x
now,
sp with vat=sp+vat amount
=4500-45x+450-45x
=4950-90x
now,
4950-90x=4400
or,-90x=-550
or, x=55/9
or, x=6.11%
therefore, dis percent is 6.11%
9514 1404 393
Answer:
11.11%
Step-by-step explanation:
Let d represent the discount, as a fraction. Then the final price is ...
4500(1 -d)(1 +10%) = 4400
1 -d = 4400/(1.10·4500)
d = 1 - (4400/4950) = 0.111... ≈ 11.11%
The discount percentage is about 11.11%.

Evelyn is trying to make extra money on her summer vacation from school. She
works two different jobs, earning $11 per hour washing cars and $13 per hour
clearing tables. How much money would Evelyn earn in a week in which she worked
3 hours washing cars and 7 hours clearing tables? How much money would Evelyn
earn in a week in which she worked x hours washing cars and y hours clearing
tables?
Answer:
Washing Cars: $33
Clearing Tables: $91
Step-by-step explanation: Multiply 11 by 3, and multiply 13 by 7. I hope I helped!
Step-by-step explanation:
for every 1 hour she works she gets 11 dollars washing the cars, so you multiply the number of hours by the amount of money she gets each hour. Like so,
11 x 3 = 33, so 33 dollars from washing cars
next - 13 x 7 = 91 dollars from house cleaning
add together the amount of each so, 33 + 91 = 124, 124 is the answer.

Based on his skills in basketball, it was computed that when Joe Sureshot threw a free throw, the odds in favor of his making it were 4 to 35. Find the probability that when Joe shot a free throw, he made it. Out of every 100 free throws he attempted on the average how many did he miss?
Answer:
11.43%
89 free throws would miss
Step-by-step explanation:
In order to find the percentage probability of Joe making a free throw show we need to the odds given and then multiply that decimal value by 100 like so...
4 / 35 = 0.11428
0.11428 * 100 = 11.43% rounded up
If Joe were to shoot 100 free throws 11.43% would most likely go in but since the actual number can only be a whole number it would mean that 11 of those 100 free throws would go in.
100 - 11 = 89
Therefore, 89 free throws would miss on average.

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:
y < 4x − 2
y is greater than or equal to negative 5 over 2 times x minus 2
Part A: Describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area. (6 points)
Part B: Is the point (−2, −2) included in the solution area for the system? Justify your answer mathematically. (4 points)
(10 points)
if you abuse the amount of points I put on this question I will report you
Answer:
Photo.
Step-by-step explanation:
A: The graph of the system is all points in the graph that suit 4x-2<y</=-5/2x-2
B: The point (-2,-2) is not included in the solution area. While it suits the second equation, it doesn't suit the first, ruling it out as a possible solution. If you plug in -2 as both y and x in the equation 4x-2>y, you'll get -8>-2, which is false. So, it is not a solution.

Jamel wants to buy a PS 5. He found it for $500
with a 30% discount on Black Friday. How much
would he pay before taxes ?..
Answer:
150
Step-by-step explanation:
its 150 without taxes
Answer:
350
Step-by-step explanation:
Assumung that the $500 is before taxes, Jamel would have to pay $350.
$500 = price before discount
30% = discount
This means that Jamel would be paying 70% of the orginal price, because 30% of it is already taken off.
0.7*500=350
