A: apples
b: bananas

Your expression could be:

$0.80a + $0.60b = $10.00

----

$0.80 ( 8 ) + $0.60 ( 6 ) = $10.00
$6.40 + 3.60 = $10.00
$10.00 = $10.00

Which line is parallel to a line that has a slope of 3 and a y-intercept at (0, 0)?
anyanavicka [17]

we know that

If two lines are parallel , then their slopes are the same

we will proceed to calculate the slope of each line to determine the solution.

The formula to calculate the slope m between two points of the line is equal to

m=\frac{(y2-y1)}{(x2-x1)}

<u>case N 1) </u>line AB

Let

A(-4,3)\\B(4,3)

substitute the values

m=\frac{(3-3)}{(4+4)}

m=\frac{(0)}{(8)}

m=0

0\neq 3

therefore

<u>The line AB is not the solution</u>

<u>vase N 2)</u> line FG

Let

F(-3,-1)\\G(3,-3)

substitute the values

m=\frac{(-3+1)}{(3+3)}

m=\frac{(-2)}{(6)}

m=-1/3

-1/3\neq 3

therefore

<u>The line EG is not the solution</u>

case N 3) line CD

Let

C(-3,0)\\D(3,2)

substitute the values

m=\frac{(2-0)}{(3+3)}

m=\frac{(2)}{(6)}

m=1/3

1/3\neq 3

therefore

<u>The line CD is not the solution</u>

case N 4) line HJ

Let

H(-1,-4)\\J(1,2)

substitute the values

m=\frac{(2+4)}{(1+1)}

m=\frac{(6)}{(2)}

m=3

3=3

therefore

<u>The line HJ is  the solution</u>

therefore

<u>the answer is the option</u>

line HJ

The graph of the parent function y = x cubed is horizontally stretched by a factor of One-fifth and reflected over the y-axis. W
sasho [114]

Answer: OPTION D.

Step-by-step explanation:

Below are some transformations for a function f(x):

If -f(x), then the function is reflected over the x-axis.

If f(-x), then the function is reflected over the y-axis.

If f(bx)  and b>1, then the function is horizontally compressed.

If  f(bx)  and 0 < b, then the function is horizontally stretched.

In this case you know that the parent function is:

y=x^3

According to the information given in the exercise, the parent function IS horizontally stretched by a factor of \frac{1}{5} and it is also reflected over the y-axis.

Therefore, based on the transformations explained before, you can notice that the transformation is:

f(-bx)

Where 0 < b

Therefore, the equation of the transformed function is:

y=(-\frac{1}{5}x)^ 3
