25x^2 = 16
divide each side by 25
x^2 = 16/25
take the square root of each side
sqrt (x^2) = +- sqrt(16/25)
x = +- sqrt(16)/sqrt(25)
x = +- 4/5
x = 4/5, - 4/5
First add 54+78 which is 132. Then do 132 divided by 6 which is 22. 22 is the answer! When u need help ask me ok
slope (m) = (y₂ - y₁)/(x₂ - x₁)
-2/1 = (a - 1)/(5 -(-5))
-2 = (a - 1)/10
-20 = a - 1
-19 = a
Answer: a = -19
Answer:
80
Step-by-step explanation:
The equation of finding a slope is y2-y1/x2-x1.
y-5/-7-(-21)=5
y-5/-7+21=5
y-5/15=5
y-5=75
y=80
