Answer:

y = - 4

Step-by-step explanation:

x = - 1 is the equation of a vertical line parallel to the y- axis

The equation of a line perpendicular to it will therefore be a horizontal line parallel to the x- axis with equation

y = c

where c is the value of the y- coordinates the line passes through.

The line passes through (8, - 4 ) with y- coordinate - 4 , then

y = - 4 ← equation of perpendicular line

38 students need 88ml of acid how many 1l bottles are needed

Ilia_Sergeevich [38]

1 mL = 1*10^-3 L

1. Which of the following shows the correct use of the Distributive Property when solving 1/3( 33

vagabundo [1.1K]

Answer:

The option $(\frac{1}{3}\times 33)-\frac{1}{3}y=\frac{1}{3}135.2$ is correct

Step-by-step explanation:

Given equation is $\frac{1}{3}(33-y)=135.2$

The option shows correct usage of distributive property is

$(\frac{1}{3}\times 33)-\frac{1}{3}y=\frac{1}{3}135.2$

( by distributive property $a(x+y)=ax+ay$ here $a=\frac{1}{3}$ , x=33 and y=-y )

Therefore the option $(\frac{1}{3}\times 33)-\frac{1}{3}y=\frac{1}{3}135.2$ is correct.
