Answer:
27
58
61
82
23
53
Step-by-step explanation:
4 - 5x = 59
Subtract 4 from both sides:
-5x = 55
Since x is being multiplied by -5, the next step is to divide both sides by -5.
<u>y = 25</u>
Step-by-step explanation:
<u>=> 115 = y + 90 {exterior angle of triangle is equal to the sum of its opposite two interior angles}</u>
<u>=> 115 = y + 90 </u>
<u>=> 115-90 =y</u>
<u>=> 115 = y + 90</u>
<u>=> 115-90 =</u><u>y</u>
<u>=> y = 25</u>
Convert to slope intercept form (y=mx+b).
2x-4y=8
subtract 2x from each side
2x-2x-4y=-2x+8
-4y = -2x+8
divide by -4
y = -2/-4 x +8/-4
y = 1/2 x -2
it is now in slope intercept form
