Answer:
y =-3
Step-by-step explanation:
4(y+1)=-8
Divide each side by 4
4/4(y+1)=-8/4
y+1 = -2
Subtract 1 from each side
y+1-1 = -2-1
y = -3
Answer:
y-intercept is (0, 3)
Step-by-step explanation:
To find the y-intercept, substitute in 0 for x and solve for y.
Answer:
x = 19
<B = 125°
Step-by-step explanation:
The sum f angle <D and angle <A is equal to 180° because these angles are supplementary
75° + 5x + 10 = 180° add like terms
85 + 5x = 180 subtract 85 from both sides
5x = 95 divide both sides by 5
x = 19
Same rule goes for angle <C and angle <B
<B + 55° = 180 subtract 55 from both sides
<B = 125°
Ordered pair is (x,y)
Looking at the red dot, x is 0 and on the y axis, y is -3, thus it gives us an order pair of (0,-3)
The answer is C, (0,-3)
Hopes this helps! :D
