Slope is rise over run or (y₁-y₂)/(x₁-x₂)
(x,y)
(1,3)
(3,-2)
(3-(-2))/(1-3)=(3+2)/(1-3)=5/-2
slope is -5/2
x^2 = 100...by taking the square root of both sides, this eliminates the ^2
x = (+-) sqrt 100
x = (+-) 10
so the values of x are -10 and 10
1/9 of a yogurt can be bought with 5 pounds.
If you were to replace the x's with 2, your equation would turn into:
(2)^2-4(2)+5
From there, you'd just solve.
4-8+5=1
Your answer would be 1.
Answer:
The correct set of equations is C.
Step-by-step explanation:
m + n = 32
m = 3n
We have 4n = 32, so n = 8 and m = 24.
