Sample Response: There is no solution to the system in its original form. There are no points in common. If the signs are reversed, the system has an intersection with an infinite number of solutions.
What did you include in your response? Check all that apply.
The shaded area would reverse on both inequalities.
The graphs do not overlap until the signs are reversed.
There are an infinite number of solutions in the system once the signs are reversed.

Answer:
The answer is 286.
Explanation:
We first find the first term of the sequence, a₁. We use the explicit formula for an arithmetic sequence to do this:
We know the 6th term is 22; this means we substitute 6 in for n. We also know the common difference is 6, so we use that for d. That gives us a₆=a₁+6(6-1).
We know the value of the sixth term is 22, so we use that instead of a₆:
22=a₁+6(6-1).
Evaluating this, we have
22=a₁+6(5)
22=a₁+30.
Subtract 30 from both sides, and we have
22-30=a₁
-8=a₁.
We now use this value in our explicit formula:
To find the fiftieth term we replace n with 50:
a₅₀= -8+6(50-1)
a₅₀= -8+6(49)
a₅₀= -8+294
a₅₀=286
If the perimeter of the triangle is 40 cm, find the area of the triangle.
The area of the triangle is, ? cm2.
Answer:
102 cm²Step-by-step explanation:
Perimeter is:
P = 40 cmand P = 2x - 4 + 5x - 13 + x + 9 = 8x - 8Comparing the value:
8x - 8 = 40 8x = 48x = 8 cmAre formula:
A = 1/2ahReplacing values:
A = 1/2(x + 9)(2x - 4)A = 1/2(8 + 9)(2*8 - 4) = 1/2*17*12 = 102 cm²Answer:
60cm²
Step-by-step explanation:
To find :-
The Area of the triangle .We know that Perimeter is the sum of sides of a triangle. Here the perimeter is 40cm .
→ 2x - 4 +5x - 13 + x + 9 = 40cm .
→ 8x - 8 = 40cm
→ 8x = 40+8 cm
→ 8x = 48 cm
→ x = 6cm .
We know that the area of the triangle is half the product of base and height .
Base = x + 9 = 15cm Height = 2x -4 = 8cm .→ A = 1/2 × b × h
→ A = 1/2 × 8cm × 15cm
→ A = 60cm²

Answer:
angle t is 55 degrees
Step-by-step explanation:
Here's my work:
Isoscelese means two of the same length sides. A triangle is 180 degrees. 180-70=110
110/2=55 (two because those are the two angles associated with the equal sides)

my teacher sent me a really passive aggressive email. any ideas of how to respond in a passive aggressive way without getting in trouble. here's some context for what the email was about. So I had to submit something online but I'm having issues doing it. I figured out a way to do it but he wants me to do it a different way. the way he wanted me to do it didn't work so I asked him if I could just do it my way. he told me that I'm the only one having the issue and asking him if it's ok to submit it my way would be a burden for him to grade(which honestly it wasn't, all it would take him is an extra minute) he also said that I should develop some persistence and figure out the issue. (this was an assignment due 2 months ago and the semester is almost over, he said that if I don't get it in I'll get a 0 for it. that's why I asked for him to grade it the way I submitted it.)
so any ideas on how to respond.

The baseball team has a double-header on Saturday. The probability that they will win both games is 42%. The probability that they will win the first game is 60%, What is the probability that the team will win the second game given that they have already won the first game?
The probability that the team will win the second game given that they have already won the first game is 7/10
Event win in the 1st game is represented with A
Event win in the 2nd game is represented with B
In the question
i. The probability that they will win both games is P(AnB) = 42%
ii. The probability that they will win the first game is P(A) = 60%
The probability that the team will win the second game given that they have already won the first game is:
P(B/A) = P(BnA) / P(A)
P(B/A) = P(AnB) / P(A)
From the question
P(B/A) = 42% / 60%
P(B/A) = 0.42 / 0.60
P(B/A) = 7/10
In conclusion: The probability that the team will win the second game given that they have already won the first game is 7/10

What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
5x+8y=20
8y=-5x+20
Divide both sides by 8
y=-5/8x+20/8
y=-5/8x+5/2
Now put x=0 to find y intercept
y=5/2
Now put y=0 to find x intercept
-5/2=-5/8x
4=x
Hence, x intercept is (4, 0) and y intercept is (0,5/2).

Write the slope-intercept form of the equation that is described below.
Through (3, 3) and perpendicular to y = 14x − 2
What is the equation?
Answer:
y = -¹/₁₄x + 3³/₁₄Step-by-step explanation:
If two lines are perpendicular then the product of theirs slopes is equal -1:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇒ m₁×m₂ = -1
y = 14x - 2 ⇒ m₁=14
14×m₂ = -1 ⇒ m₂ = -¹/₁₄
The line y=-¹/₁₄x+b passes through point (3, 3) so the equation:
3 = -¹/₁₄×3 + b must be true
3 = -³/₁₄ + b
b = 3³/₁₄
Therefore equation in slope-intercept form:
y = -¹/₁₄x + 3³/₁₄
Ms. Davis counts 12 large boxes and 18 small boxes of pencils in the supply cabinet. Each large box contains 144 pencils. Each small box contains 24 pencils. Estimate the number of pencils. Is your estimate an underestimate or an overestimate? The find the exact answer.
Answer:
Estimated amount of pencils = 2040 pencils
Exact amount of pencils = 2160 pencils
Step-by-step explanation:
Estimated amount of pencils are calculated by:
rounding up the numbers to the nearest tens
large box= 144 pencils = 140 pencils
small box = 24 pencils = 20 pencils
Estimated number of pencils =
(12 × 140) + (18 × 20)
= 1680 + 360
= 2040 pencils
This is an underestimate
The exact number of pencils is calculated as:
(12 × 144 pencils ) + (18 × 24 pencils)
= 1728 pencils + 432
= 2160 pencils
please help fast. - a pair of equations are shown below:
y = 7x - 8
y = 5x - 2
Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
y = 7x - 8 → (1)
y = 5x - 2 → (2)
A
Solving by substitution
Substitute y = 7x - 8 into (1)
7x - 8 = 5x - 2 ( subtract 5x from both sides )
2x - 8 = - 2 ( add 8 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Substitute x = 3 into either of the 2 equations and evaluate for y
Substituting into (1)
y = 7(3) - 8 = 21 - 8 = 13
Solution is (3, 13 )
B
The point of intersection of the graph of the 2 equations is the solution to the above equations.
That is point of intersection = (3, 13 )

13) How do you know when to use the mean or median as the best measure of center?
Answer:
The mean is the most common measure of center. It is what most people think of when they hear the word "average". However, the mean is affected by extreme values so it may not be the best measure of center to use in a skewed distribution. The median is the value in the center of the data.

Heng was trying to factor 10x^2+5x. She found that the greatest common factor of these terms was 5x5x5, x and made an area model:
Answer:
[tex]Width = 5x + 1[/tex]
Step-by-step explanation:
Given
[tex]Area = 10x^2 + 5x[/tex]
[tex]Length = 5x[/tex]
Required (Missing)
Determine the Width?
Area is calculated as:
[tex]Area = Length * Width[/tex]
Substitute values for Area and Length
[tex]10x^2 + 5x = 5x * Width[/tex]
Factorize the right hand side
[tex]5x(5x + 1) = 5x * Width[/tex]
Divide both sides by 5x
[tex]5x + 1 = Width[/tex]
Hence, the width of the model is 5x + 1
Greg went to Bed Bath and Beyond to buy Christmas gifts for his family this year. In his first trip he bought 4 candles, 5 wallflowers, and 6 lotions for a total of $123. Greg forgot some people on his list the first time so he makes a second trip and spent $48 to buy 2 candles, 3 wallflowers, and 1 lotion. The price of a lotion is 2 less than 2 times the price of a wallflower. How much does each item cost?
Answer:
Price of Candle: 12.5
Price Wallflower: 5
Price of Lotion: 8
Step-by-step explanation:
Let cost of a candle = [tex]x[/tex]
Let cost of a wallflower = [tex]y[/tex]
Let cost of a lotion = [tex]z[/tex]
Cost of 4 candles = 4[tex]x[/tex]
Cost of 5 wallflowers = 5[tex]y[/tex]
Cost of 6 lotions = 6[tex]z[/tex]
Cost of 2 candles = 2[tex]x[/tex]
Cost of 3 wallflowers = 3[tex]y[/tex]
Cost of 1 lotion = [tex]z[/tex]
As per question statement:
[tex]4x+5y+6z=123 .... (1)\\2x+3y+z=48 ...... (2)\\z=2y-2 ..... (3)[/tex]
Using equation (3) in (1) and (2), the equations get reduced to :
[tex]\Rightarrow 4x+17y = 135 ..... (4)\\\Rightarrow 2x+5y = 50 ..... (5)[/tex]
Multiplying (5) with 2 and subtracting from equation (1):
[tex]7y = 35\\\Rightarrow y = 5[/tex]
By equation (3):
[tex]\Rightarrow z =8[/tex]
By equation (4):
[tex]\Rightarrow x = 12.5[/tex]
Therefore, the answer is:
Price of Candle: 12.5
Price Wallflower: 5
Price of Lotion: 8
