Answer:
x=-1 and x=5
Step-by-step explanation:
we have
Solve it by completing the square method
We take the coefficient of x that is -4, divide it by 2 and then square it
so
square it
Adds 4 both sides
Combine like terms right side
Rewrite as perfect squares
take square root both sides
therefore
45 = 1/2(a - 65)
90 = a - 65
155 = a
Answer:
y = -1/3x + 4
Step-by-step explanation:
Slope-intercept form is y=mx+b where m is slope and b is y-intercept. Substituting the given slope of -1/3 in for m and the given y-intercept of 4 in for b, the equation of the line would be y = -1/3x + 4. Hope this helps :)
The correct answer is:

Answer:
x = -10
Step-by-step explanation:
3(x+1) +5 = 2x -2
<em>Distribute the 3 to the x+1</em>
3x+3 +5 = 2x -2
<em>Combine like terms</em>
3x + 8 = 2x -2
<em>Subtract 2x from both sides</em>
x + 8 = -2
<em>Subtract 8 from both sides</em>
x = -10
