4(5x + 9)^2 – 33 = -21

Answer:

x = sqrt(3)/5 - 9/5 or x = -9/5 - sqrt(3)/5

Step-by-step explanation by completing the square:

Solve for x over the real numbers:

4 (5 x + 9)^2 - 33 = -21

Add 33 to both sides:

4 (5 x + 9)^2 = 12

Divide both sides by 4:

(5 x + 9)^2 = 3

Take the square root of both sides:

5 x + 9 = sqrt(3) or 5 x + 9 = -sqrt(3)

Subtract 9 from both sides:

5 x = sqrt(3) - 9 or 5 x + 9 = -sqrt(3)

Divide both sides by 5:

x = sqrt(3)/5 - 9/5 or 5 x + 9 = -sqrt(3)

Subtract 9 from both sides:

x = sqrt(3)/5 - 9/5 or 5 x = -9 - sqrt(3)

Divide both sides by 5:

Answer: x = sqrt(3)/5 - 9/5 or x = -9/5 - sqrt(3)/5

Math question plz help me

Answer:

The required equation of the line is:

$y=\frac{1}{4}x-1$

Step-by-step explanation:

Given the equation

$y=-4x+3$

comparing the equation with the slope-intercept form

$y=mx+b$

Here,

m is the slope

y is the intercept

so the slope of the line is -4.

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

The slope of the perpendicular line will be: 1/4

Therefore, the point-slope form of the equation of the perpendicular line that also intersects the point (8, 1) is:

$y-y_1=m\left(x-x_1\right)$

$y-1=\frac{1}{4}\left(x-8\right)$

add 1 to both sides

$y-1+1=\frac{1}{4}\left(x-8\right)+1$

$y=\frac{1}{4}x-1$
