Answer:

R = 101

S = 131

Step-by-step explanation:

First, you will want to get your angle T. Since T is on the same line as the angle with 128 degree, you can easily find angel T. They are supplementary angels and form 180.

T=180-128

T=52

You also know that all angles in a triangle equal to 180

Use that to find angle S

180 = R+S+T

180 = 79 + S + 52

180 - 79 - 52 = S

49 = S, exterior S = 180-49 = 131

Exterior R = 180 - 79 = 101

Now add all your exteriors

Answer:

Step 4

Step-by-step explanation:

Step 4 is incorrect because when you add the number from the right side, -34, you make it a positive coming to the left side, -17, which stays the same. so 34+-17, will give you 17.

This will make Step 4: Addition property of equality: -17x=40

Therefore Step 5 is also incorrect, and should look like: Step 5: Division Property of Equality: x= 40/-17

FIND THE VERTEX AND GRAPH THE PARABOLA OF
DochEvi [55]

════════ ∘◦❁◦∘ ════════

<h3>Answer : (-2,11)</h3>

════════════════════

<h3>Known that</h3>

y = -2x² - 8x + 3

════════════════════

<h3>Way to do + explanation</h3>

#First, find the x coordinate first by using the formula of -b/2a

x = -b/2a = -(-8)/2(-2) = 8/-4 = -2

#After getting the x, find the y

y = -2(-2)² - 8(-2) + 3

y = -2×4 +16 + 3

y = -8 + 16 + 3

y = 11

So the vertex is

(-2,11)

-7x-3=25 (combine like terms)
-7x= 28 (add 3 on both sides)
x= -4 (divide -7 on both sides
