46: 24a+40

First we are going to take a look at a) 8(3a+5)

a) We then simplify it by multiplying the numbers inside the parenthesis by 8.

a) 24a+40

Now we ask ourselves, is this equivalent to 24a+40? YES! 

So your answer for #46 is a)   8(3a+5)

Need help not sure what to do

5a)

2x + 94 = 7x + 49 (vertical angles are equal)

2x - 7x = -94 + 49

-5x = -45

x = 9

Answer

9

5b)

4y + 7x + 49 = 180 (supplementary angles, sum = 180)

4y + 7(9) + 49 = 180

4y + 112 = 180

4y = 68

y = 17

Answer

17

6)

x = 6x - 290 (vertical angles are equal)

-5x = -290

  x = 58

Answer

58

Write the parametric form of the line, then graph the results. - 6x + 18y = 36
sesenic [268]

Answer:

x = 3t, y = t + 2

Draw a straight line connecting:

(0,2) and (2,-6)

Step-by-step explanation:

- 6x + 18y = 36

18y = 6x + 36

3y = x + 6

y = x/3 + 2

Let x = 3t

Then y = t + 2

Graph:

y = x/3 + 2

Intercepts

x-intercept:

0 = x/3 + 2

x/3 = -2

x = -6

y-intercept:

y = 0 + 2

y = 2

Draw a straight line connecting:

(0,2) and (2,-6)
