we have the equation
Solve for x
That means ----> isolate the variable x
step 1
Subtract 5 on both sides
step 3
Multiply by 3 on both sides
<h2>The answer is x=9</h2>
Answer:
Vertical opposite angles are the same so the answer is D.
So 13x5=65 and 7*6=42, add them up and get 107. So, Paul saved $107 for 11 weeks
Answer:
1
Step-by-step explanation:
They are similar triangles and ED and AD are 9 so CB and AB must be 1.
Answer:
(0 , 1), (4, 9).
Step-by-step explanation:
y = x2 – 2x+1
y = 2x+1
Substitute y = 2x + 1 into the first equation.
2x + 1 = x^2 - 2x + 1
x^2 - 2x - 2x = 0
x^2 - 4x = 0
x(x - 4) = 0
x = 0, 4.
When x = 0, y = 1.
When x = 4, y = 8 + 1 = 9.
