10) should be T= 13/4
You multiply both equations by 4 and the least common multiply of 4,2. Then 8 x 4 + 3 - 4t = 2 ( 5 x 2 +1 ) multiply 8 and 4 to get 32. Add 32 and 3 to get 35. Then you multiply 5 and 2 = 10 add 10 and 1 = 11 multiply 2 and 11 = 22 eventually ur equation should look like 35 - 4t =22 so you subtract 35 from 35 and 35 from 22 = -13 then you should have ur equation; -4t = -13 then you divide -4 by -4 = t so T = -13 /-4 but you simplify-13/-4 and switch the negative signs to positive ; 13/4
Let w bet the number of white cars and y the numbers of yellow cars.
"Rafael counted a total of 40 white and yellow cars" So w+y = 40.
"There were 9 times as many white cars as yellow cars" So 9Y = W
We get the system:
w+y=40 (1)
9y=w (2)
In equation (1), let's replace w by it's value from equation (2) since w=9y.
We get: 9y+y = 40
10y=40
y=4
So there's 4 yellow cars.
In equation (1), let's replace y by it's value
w+4=40
w=40-4
w=36
Rafael counted 36 white cars.
You can re-check your answer:
4+36=40 (w+y=40)
9*4=36 (9y=w)
The answer has been approved.

The equation that describes how the parent function, y = x³, is vertically stretched by a factor of 4 is y = 4x³.
<h3>We can find how the equation is vertically stretched below:</h3>
When an equation is vertically stretched, it means that the parent equation has been multiplied by a number that is more than one.
This means that the equation is multiplied by some factor.
It is given that we should describe how the parent function is vertically stretched by a factor of 4.
The parent function is given as y = x³.
Since the equation is said to be vertically stretched by a factor of 4, we must multiply the parent equation by 4 to stretch it.
Therefore, we have found the equation that describes how the parent function, y = x³, is vertically stretched by a factor of 4 to be y = 4x³.
