Answer:
Step-by-step explanation:
<u>Finding the line using the points:</u>
<u>The equation:</u>
<u>The slope is:</u>
- m = (-2 + 3)/(3-0) = 1/3
- y- intercept is -3
<u>So the line is:</u>
<u>As per the graph the line is dotted and the shaded area is above the line,. so the inequality is:</u>
So if 360 is increased by 25%, you would end up with 450 (360 x 1.25), than if the result, 450 is decreased by 50% ( 450 x .50 = 225) (450 - 225 = 225) you would end up with 225.
First organize the information we are given according to the problem.
*Angle 1 and Angle 3 are congruent.
*Angle 4 and Angle 6 are congruent.
*Angle 3 and Angle 4 are complementary. This means that the measure of angle 3 plus the measure of angle 4 equals to 90.
Now knowing this:
Angle 3 is 26.5° because it is congruent to angle 1.
Angle 4 is 63.5° because by subtracting 26.5 from 90, you'll get the sum of 63.5. Once more, this is because angles 3 and 4 are complementary.
Angles 4, 5, and 6 are adjacent angles which form a straight line. Straight lines have an angle measure of 180°. So together, both angles 4 and 6 measure 127°. Knowing that a line is 180°, the measure of angle 5 needs to be 53°. You can check this once more by adding all the three numbers and getting 180°.
Answer:
x=2 x=-2
Step-by-step explanation:
x² + 2x - 4 = 2x
Subtract 2x from each side
x² + 2x-2x - 4 = 2x-2x
x^2 -4 = 0
Factor
We know this is the difference of squares
(x-2)(x+2) =0
Using the zero product property
x-2 =0 x+2 =0
x=2 x=-2
