Please read through this carefully. I’d love to help, but I want you to understand why this is the answer and not just copy and paste.

Answer:

1. -6

2. 20

Step-by-step explanation:

1. Simply replace x with 2, since x=2. 2x -3 is the same as -3+-3, which is -6.

2. Simply replace x with 2, since x=2. 2x5 is the same as 5+5, which is 10. 10+10=20, therefore, the answer is 20.

A leaf is falling from the top of a tree. The height of the leaf in feet, y, can be found using the function y = -3.5x + 28, whe

Bess [88]

Answer:

It took 8 seconds for the leaf to reach the ground.

Step-by-step explanation:

The height of the leaf in feet can be found using the function:

y = -3.5*x + 28

where x is the time in seconds the leaf has been in the air.

You want to know how long it took for the blade to reach the ground. That is, the time it took for the blade to reach a height of 0 feet. So, replacing this value in the expression:

0= -3.5*x + 28

and solving you get:

-28= -3.5*x

(-28)÷ (-3.5)=x

8=x

<u><em> It took 8 seconds for the leaf to reach the ground.</em></u>

Purple paint is made from using red paint and blue paint in the ratio 1:2

sasho [114]

Answer:

$y = \frac{x}{2}$

Step-by-step explanation:

Given

$y : x = 1 : 2$

Required

Represent as an equation

$y : x = 1 : 2$

Represent as a fraction

$\frac{y }{ x} = \frac{1}{ 2}$

Cross multiply

$y * 2 = x*1$

Divide both sides by 2

$y = \frac{x*1}{2}$

$y = \frac{x}{2}$
