HELP ME WITH THE EXERCISES PLEAASE
Zinaida [17]
1.

1=87 corresponding angle.
2=180-87=93


2.

1=78 corresponding angles
2=78 verticle angles


3.

Set it up as (6x - 11) = 37
37 + 11 =48

6x = 48

x = 8


4.

Take 142 and see that it is supplementary to angle 2 so 180-142 = 38

38 is corresponding to the equation 2(x + 9)

So 2(x + 9) =38
Distributive property

2x + 18 = 38
38-18=20

2x =20

x = 10

Angle 2 is equal to 38 from supplementary to 142


I’m pretty positive about 1-3 but 4 maybe not be correct. But most likely these are correct

Write the equation in slope-intercept form. What are the slope and y-intercept? -5x-8y=1
FinnZ [79.3K]

Answer:

Slope= -5/8

y-intercept = -1/8

Step-by-step explanation:

ALWAYS make the equation "y=mx+c"

where m = slope/gradient and c = y-intercept

Now rearrange the equation:

5x+8y=-1

8y=-5x-1

y=-5x/8-1/8

Slope= -5/8

y-intercept = -1/8
