Answer:
5 : 1 or 10 : 2
Step-by-step explanation:
X^2 + 2x - 35
(a x b) = -35
(a + b) = 2
(7 x -5) = -35
(7 + -5) = 2
Plug them in:
x^2 - 5x + 7x -35
x(x - 5) + 7(x - 5)
Therefore, you can conclude that our final answer is...
(x + 7)(x - 5)

Answer:
A. y= 2(x - 2)2 + 4
Step-by-step explanation:
vertex having an x value of 2 means the phrase in paren must be x - 2.
This eliminates B and D
vertex having a y value of 4 is of no help as the remaining two equations will result in 4 if the x term is 2
plugging in x = 3 makes y = 6 in equation A, but not in equation C where y = 10
Answer:
One is 89 , the other is 33.
Step-by-step explanation:
Set up a system of 2 equations:
x + y = 122
x - 2y = 23 Subtracting:
0 + 3y = 99
y = 33.
So:
x + 33 = 122
x = 122 -33 = 89.
Answer:
y=9.25
Step-by-step explanation:
1. Plug in x=0.3 into the equation.
5(0.3)+2y=20
2. Simplify
1.5+2y=20
2y=18.5
3. Isolate y on the left side of the equation by dividing by 2 on both sides.
y=9.25
