Answer:
x ≈ - 6.49, x ≈ 12.49
Step-by-step explanation:
Given
(x - 3)² + 7 = 97 ( subtract 7 from both sides )
(x - 3)² = 90 ( take the square root of both sides )
x - 3 = ± 
( add 3 to both sides )
x = 3 ±
Then
x = 3 - ≈ - 6.49 ( to the nearest hundredth )
x = 3 + ≈ 12.49 ( to the nearest hundredth )
Answer:
The Answer is: y = -3x - 26
Step-by-step explanation:
Given point: (-6, -8)
Given equation:
y = -3x + 3, the slope m = -3
A parallel line has the same slope, m = 3. Use the point slope form and substitute in the point and the slope:
y - y1 = m(x - x1)
y - (-8) = -3(x - (-6))
y + 8 = -3x - 18
y = -3x - 18 - 8
y = -3x - 26
Proof - use the point (-6, -8):
f(x) = -3x -26
f(-6) = -3(-6) - 26
= 18 - 26 = -8, giving (-6, -8)

Answer:
If x=8 then the equation is equal to 33
If 1/2(x)^2-1/4x=3=8 then x=-2.98 and x=3.35
Step-by-step explanation:
Given:
1/2x^2-1/4x+3
Two solutions possible:
If x=8 then 1/2(8)^2-1/4(8)+3=32-2=3=33
If 1/2(x)^2-1/4x+3=8 then .5x^2-.25x-5=0
factoring:
(.707x+2.11)(.707x-2.37)=0
.707x=-2.11 and .707x=2.37
x=-2.98 and x=3.35 rounded to 2 places
