x² = 6x - 9, or x² - 6x + 9 = 0, or x² - 2*x*3 + 3² = 0, or (x-3)² = 0 => x₁ = x₂ = 3.

Answer:

Step-by-step explanation:
The equation of the line can be written in slope-intercept form, as y = mx + b.
We need to find the slope (m) and the y-intercept (b) of the line, then plug their values into the slope-intercept equation, to find the equation of the line shown.
y-intercept (b) = the point where the line intercepts the y-axis = 4
Using two points on the line, say, (0, 4) and (2, 3):

m = -½.
Substitute m = -½, and b = 4 into y = mx + b.
The equation of the line would be:

Answer:
The measure of the angle is 55°
Step-by-step explanation:
Take an angle A and let its complement be x°
Its supplement is 20° + 3x°
Supplementary angles add up to 180° so;
Angle A = 180° - (20° + 3x°) = 160° - 3x°
Complementary angles add up to 90° so;
x° + 160° - 3x° = 90°
-2x° = -70° , x° = 35°
So the complement of the angle A is 35°
Angle A is 90° - 35° = 55°
And its supplement is 180° - 55° = 125°
B is the answer to this question.....
Answer:
25
