Answer:
y=6x+8
Step-by-step explanation:
Since the lines are parallel, the slopes are the same. Once you have y=6x+b, you plug in (0,8) as the y-intercept and find that b=8.
An mp3 player is on sale for 30% off the regular price of $39. 98. How much is the discount? a. $11. 99 b. $13. 19 c. $13. 33 d. $27. 99 Please select the best answer from the choices provided A B C D.
The cost of the mp3 player after the discount is $27.98.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by whole and multiply by 100.
Given
An mp3 player is on sale for 30% off the regular price of $39. 98.
The price of the mp3 player after the 30% is given
[tex]\rm Cost \ of \ player \ after \ discount = Cost \ of \ player \times discount\\\\\rm Cost \ of \ player \ after \ discount = 39.98\times 0.30\\\\\rm Cost \ of \ player \ after \ discount = 11.99[/tex]
The cost of mp3 player after 30% discount is;
= $39.98 - $11.99 = $27.98
Hence, the cost of the mp3 player after the discount is $27.98.

The length of a rectangular table is represented by the function L(x) = 4x. The width of the table is represented by the function W(x) = 3x2 − 5x + 6. What is the area of the table in terms of x? (1 point)
(L • W)(x) = 7x3 − x2 + 10x
(L • W)(x) = 12x2 − 20x + 24
(L • W)(x) = 12x3 + 20x2 + 24x
(L • W)(x) = 12x3 − 20x2 + 24x
Answer:
(L • W)(x) = 12x^3 − 20x^2 + 24x (the last option)
Step-by-step explanation:
It's very simple actually. To find an area of a rectangle, all we have to do is multiply its two sides. We are given the length and the width of the rectangle - its sides. All we have to do is simply multiply them:
Area = L(x) * W(x)
L(x) = 4x
W(x) = 3x^2 - 5x + 6
Therefore the area is equal to:
(4x) * (3x^2 - 5x + 6) =
= 4x * 3x^2 - 4x * 5x + 6 * 4x =
= 12x^3 - 20x^2 + 24x
And there's your answer, option D, or 4 or whatever you call the last one.

which equation or function is linear?
A. 3xy=4
B. f(x)=2/3(1-x^2)
C. 2y=(2x-1)/4
D. y=3/x+1
9514 1404 393
Answer:
C. 2y = (2x-1)/4
Step-by-step explanation:
An equation is linear when the exponents of the variables are 1 and the sum of the exponents of the variables in any term is 1.
a) 3xy = 4 . . . . sum of exponents is 1+1=2
b) f(x) = 2/3(1 -x^2) . . . . exponent is 2
c) 2y = (2x -1)/4 . . . . all exponents are 1 (linear)
d) y = 3/(x+1) ⇒ xy +y = 3 . . . . sum of exponents is 1+1 = 2

HOW DO I SOLVE THIS HELP
Answer:
[tex]x=2\sqrt5[/tex]
Step-by-step explanation:
I'm assuming that 15 is the length of only part of the hypotenuse of the larger triangle.
The remaining part can be easily found by noticing that the red triangle is half an equilateral triangle of side x, so the missing part is x/2.
Now for a known theorem (easily proved with the fact that triangles AHC and ABC are similar) you can write the following equation containing x:
[tex]x^2 = \frac x2 ( \frac x2 +15) \rightarrowx^2 = \frac {x^2}4+15 \\\\3x^2=60 \rightarrow x^2 = 20 \\x=2\sqrt5[/tex]
(where we obviously took only the positive root since x is a lengtth measure.
It took Carrie five less minutes than twice the amount of time as Hua to complete her homework. It took Hua thirty-five minutes to complete her homework. Write a numerical expression to describe the amount of time it took Carrie to complete her homework.
Given that,
Time taken by Hua to complete her homework is 35 minutes
ATQ,
The time taken by Carrie is five less minutes than twice the amount of time as Hua to complete her homework. Let it is x minutes.
The numerical expression for this is given by :
x = 2(times taken by Hua)-5
x = 2(35)-2
Above is the numerical expression for time taken by Carrie.
We can also solve it, x = 70-2 = 68 minutes
Hence, this is the required solution.
Isabel is pulling water up from an old-fashioned well. She lifts the bucket of water at a rate of 4 ft/s, and after 1 s, the bucket is 1 ft below the top of the well. What is the equation in point-slope form of the line that represents the height of the bucket relative to the top of the well? y [ Select ] [ Select ] = [ Select ] (x - [ Select ] )
Answer:
Point slope form is y+1=4(x-1)
Step-by-step explanation:
She lifts water at a rate of 4ft/s.
After 1 second, the bucket is 1 feet below the top of the well. So, point form of this would be (1,-1).
Here, let's use the slope m= rate = 4 ft/s
Point as (1,-1)
So, y-(-1)= 4(x-1)
Simplify, it gives
y+1= 4(x-1)

Charlene is knitting a baby blanket. She wants its width, w, to be at least half its length, l. She estimates that she has enough yarn to put fringe around the blanket, as long as the perimeter of the blanket is no more than 180 inches. The system of inequalities shown represents the width of the blanket in inches, w, and the length in inches, l.
w ≥ 0.5l
2l + 2w ≤ 180
What is the maximum length possible for her blanket?
30 inches
45 inches
60 inches
90 inches
Answer:
C 60 inches
Step-by-step -
60 x 2 = 120, which is both lengths, and since he width is half the length, then 30 x 2 = 60. So 130 (length) + 60 (width) = 180. So 60 inches would be the maximum length for both sides.

C

John takes 15 minutes to get to school. The bell rings at 9:00a.m. John wants to get there 5 minutes before the-bell. At what time should John leave home?
Answer:
8:40 a.m.
Step-by-step explanation:
Let's start by finding the time John should arrive at school.
9:00 a.m. - 5 minutes = 8:60 a.m. - 5 minutes = 8:55 a.m.
Note that there are 60 minutes in an hour
Now, we find the time he should leave home...
8:55 a.m. - 15 min = 8:40 a.m.
Therefore John should leave at 8:40 a.m.
Another way to solve this problem:
John needs to leave home in "x" minutes before 9:00 a.m. to arrive when the bell rings (9:00 a.m.). To find "x", we need to add 15 and 5 to get:
15 min + 5 min = 20 min.
Therefore he must arrive 20 minutes before 9:00 a.m.
9:00 a.m. - 20 min = 8:40 a.m.
Therefore John should leave at 8:40 a.m.
3 = 0.2m - 7
i need to show my work pls hurry!
[tex]3 = 0.2m - 7[/tex]
[tex]3 + 7 = 0.2m[/tex]
[tex]10 = 0.2m[/tex]
[tex] \frac{10}{0.2} = m[/tex]
plug it on your calculator or multiply 10 by 5
[tex]m = 50[/tex]
