To answer this question you can write an equation that represents this situation.

I would subtract $11 (the cost per shirt) from the selling price to get $15 profit for each shirt. He paid $100 already and wants to profit $400, so the amount he needs to make is $500.

$15x = $500 would be the equation needed to answer this. x stands for the number of shirts.

Divide both sides by $15 to get
x = 33.33.... shirts.

He would need to sell at least 34 to make at least $400 profit.

Write the ordered pair that represents YZ Then find the magnitude of YZ. Y (4,2) Z(2,8)

jarptica [38.1K]

For the given points $Y(4,2)$ and $Z(2,8)$ , we have to find the ordered pair that represents YZ.

YZ is calculated by finding the difference between the coordinates Z and Y.

So,

$YZ = Z- Y$

$YZ = (2,8)- (4,2)$

$YZ = (2-4,8-2)$

$YZ = (-2,6)$

Magnitude of coordinate (x,y) is calculated by the formula = $=\sqrt{x^{2}+y^{2}}$

Magnitude of YZ= $\sqrt{(-2)^{2}+(6)^{2}}$

= $\sqrt{4+36}$

$=\sqrt{40}$

$=2\sqrt{10}$ units.

Leah is writing an equivalent equation which solves for y. What should be her next step? 3x+4y=8 Add 4y to both sides of the equ

ratelena [41]

The given equation is

$3x+4y=8$

And we have to solve for y.

Solving for y, means isolating y . And to isolate y, we need to get rid of 4 that is with y .

It means we have to separate 4 from y, and for separation , we have to perform division. That is, we have to divide both sides by 4, and that will be the next step .

So out of the four options, correct option is the last option .
