Ответ:
6. Find slope
(0-2)/(2+3) = -2/5
y - 2 = -2/5 (x + 3)
Y = -2/5x - 1.2 + 2
Slope intercept: y = -2/5x + 0.8
8. Slope: (-1+4)/(5+7) = 1/4
y + 4 = 1/4(x+7)
Y = 1/4x + 1.75 - 4
Y = 1/4x - 2.25
Ответ:
X = 12
Step-by-step explanation:
Each angle has 90 degrees, so we know that 4x + 7 = 55. Then, we take off the 7 to get 48, so then 4x = 48. Divide that all by 4 and we get X = 12!
Hope this helped!
