In y=mx+b, m= slope and b= y-intercept. All you have to do is substitute.

1)  y= \frac{3}{2} x-2

2) 
y=  \frac{-1}{2}x-1

3) y=-0.5x+2.5

In this figure, AB¯¯¯¯¯∥CD¯¯¯¯¯ and m∠3=120°.<br><br> What is m∠6?
victus00 [196]

Answer:

The  m∠6 is 60 °.

Step-by-step explanation:

As given in  the figure

AB∥CD and m∠3=120°.

As AB and CD are parallel lines and a transversal line passing through AB and CD .

∠ 3 and ∠6 are same side interior angles .

Now by using the property

When two lines are parallel and tansversal passing through  parallel lines than same sides interior angles are supplementary .

Thus

∠3 + ∠6 = 180 °

( m∠3=120° )

120 ° + ∠6 = 180 °

∠6 = 180 ° - 120 °

∠6 = 60 °

Therefore the  m∠6 is 60 °.

Let x = cups of 11% wheat, and y = cups of 63% wheat

He wants 12 cups in total, so we need:

x + y = 12

These 12 cups need to have 50% wheat, which means we are looking at 12*.5 = 6 cups of wheat in total, so our second equation is:

.11x + .63y = 6

We have two equations and two variables.  So we can solve by using any means you want.  I used substitution:

x = 12 - y

.11(12-y) + .63y = 6

1.32 -.11y + .63y = 6

.52y = 4.68

y = 9

Which means x = 3

Thus, 3 cups of 11% and 9 cups of 63%.
