Answer:
x = - , x = 3
Step-by-step explanation:
Given
(4x - 5)² = 49 ( take the square root of both sides )
4x - 5 = ± = ± 7 ( add 5 to both sides )
4x = 5 ± 7, thus
4x = 5 - 7 = - 2 ( divide both sides by 4 )
x = = -
or
4x = 5 + 7 = 12 ( divide both sides by 4 )
x = 3
As a check
Substitute these values into the left side of the equation and if equal to the right side then they are the solutions.
x = -
left side = (- 2 - 5)² = (- 7)² = 49 = right side ⇒ solution
x = 3
left side = (12 - 5)² = 7² = 49 = right side ⇒ solution
N-8 or 8-n I would assume
Answer:
where are the ordered pairs
Step-by-step explanation:
Answer:
slope = -3/4
Step-by-step explanation:
Slope:
−
3/4
y-intercept:
13
/4
Any line can be graphed using two points. Select two values, and plug them into the equation to find the corresponding values.
x | y
0 | 13
/4
1 | 5/
2
