Answer:
combine like terms i think
Step-by-step explanation:
Answer:
First, add the like terms (14x +11x), which equals 25x.
25x+10=85
25(3)+10=85
X=3
Step-by-step explanation:
Answer:
8.2
Step-by-step explanation:
The distance formula is
In this case, x_1 = 2, y_1 = 7, x_1 = 4, y_1 = -1.
We can plug in these values, getting
f(s) =10 (s-65)+75
Answer:
C. a = 3
b = 7
c = -20
Step-by-step explanation:
x = -b+/- (sq) b^2 - 4ac.
Well the way to plug the numbers in is by using this equation: Ax^2 + Bx + C = 0
S if you use your equation : 3x^2 = 20 - 7x
First you have to move everything to one side.
So it'll look like this:
3x^2 = 20 - 7x
-20 -20
3x^2 - 20 = -7x
+7x +7x
3x^2 - 20 + 7x = 0
don't forget that... Ax^2 +Bx+ C= 0
3 = A
7 = B
-20 = C
