Answer:
The answer is x = 7
Step-by-step explanation:
√2x − 5 + 4 = x
= √2x − 5 + 4 + − 4 = x + −4 (add -4 to both sides)
=√2x − 5 = x − 4
=√2x−5=x−4
2x−5=(x−4)2 (Square both sides)
2x−5=x2−8x+16
2x−5−(x2−8x+16)=x2−8x+16−(x2−8x+16)(Subtract x^2-8x+16 from both sides)
−x2+10x−21=0
(−x+3)(x−7)=0 (Factor left side of equation)
−x+3=0 or x−7=0 (Set factors equal to 0)
x=3 or x=7

Answer:
Step-by-step explanation:
The standard way of writing equation of a line in a point-slope form is as given;
y - y0 = m(x-x0)
m is the slope of the line
(x0,y0) is a point on the line.
Given the point (-2,-6), in order to determine with of the equation that correctly uses the point, we will substitute the point into the formula and get the necessary equation.
y - y0 = m(x-x0)
y - (-6) = m(x-(-2))
y+6 = m(x+2)
Since we are not given the slope, let's assume the slope is 5/2
The equation becomes y+6 =5/2(x+2). Option D is correct
