Answer:
x = 3
Step-by-step explanation:
Given
= x - 4 ( square both sides )
- x 4 = (x - 4)² ← expand
- x + 4 = x² - 8x + 16 ( subtract - x + 4 from both sides )
0 = x² - 7x + 12 ← in standard form
0 = (x - 3)(x - 4) ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 4 = 0 ⇒ x = 4
As a check
Substitute these values into the equation and if both sides are equal then they are the solutions
x = 3 :
=
= 1
right side = 3 - 4 = - 1
left side ≠ right side ⇒ extraneous solution
x = 4 :
= 0 and right side = 4 - 4 = 0
left side = right side ⇒ x = 4 is the solution
Answer:
y=-5/3x+3
Step-by-step explanation:
To find slope intercept form, distribute the slope into the parenthesis:
y+2=-5/3x+5
Subtract 2 from both sides
y+2=-5/3+5
-2 -2
y=-5/3x+3
Answer:
C. Solving this equation results in the statement -48 = 48. Because this is a false statement, the equation has no solution.
Step-by-step explanation:
8(3x - 6) = 6(4x + 8)
24x - 48 = 24x + 48
minus 24x from both sides and you get -48 = 48
A false statement means one side does not equal the other. False statement always means no solution
you can solve this equation for x, but looking at the answers it's not what the question is asking for
