Step-by-step explanation:
A line is perpendicular to y=-2x+5 and intersects the point (-4,2) what is the equation of this perpendicular line
Answer:
2y - x = 8
Step-by-step explanation:
First get the slope of the line given
y=-2x+5
From the line, slope m = -2
The slope of the required line M = -1/-2 = 1/2
Substitute the point (-4, 2) and m = 1/2 into the point slope equation;
y - y0 = m(x-x0)
y - 2 = 1/2(x+4)
2(y-2) = x+ 4
2y - 4 = x+4
2y - x = 4+4
2y - x = 8
Hence the equation of this perpendicular line is 2y - x = 8

Answer:
positivenegativedecreasingincreasingStep-by-step explanation:
1. These are intervals where the graph is above the x-axis, hence positive.
2. These are intervals where the graph is below the x-axis, hence negative.
3. The first interval is between the left peak and the valley, where the graph is decreasing. The second interval is right of the right peak, where the graph is also decreasing.
4. The first interval is left of the left peak, where the graph is increasing. The second interval is between the valley and the right peak, where the graph is also increasing.

The measure of the exterior angle of the triangle is
The question is incomplete below you will find the missing part.
The measure of the exterior angle of the triangle is
The missing picture is shown below.
The measure of exterior angle of the triangle is 92°.
As we know, the measure of the exterior angle of triangle is the sum of the two interior opposite angles of the triangle. In other words, we can say that the sum of two interior angles in the triangle is equal to the exterior angle which is supplementary to the third interior angle of the triangle.
So here the exterior angle of the triangle is given by (2x-2)°
the measure of its two interior opposite angles of the triangle will be x° and 45°.
So using the above concept
the measure of exterior angle = sum of the two interior opposite angles
⇒ 2x-2= x+45°
⇒2x-x = 45°+2°
⇒x =47°
the measure of exterior angle will be = 2x-2= (2*47°)-2 =92°
Therefore the measure of exterior angle of the triangle is 92°.

What is the slope intercept form.
Answer:
y = -[tex]\frac{3}{7} x - 2[/tex]
Step-by-step explanation:
slope-intercept form : y = mx + b
Solve for y.
Subtract 3x on both sides. You get --> 7y = -3x - 14
Divide by 7 on both sides. You get --> y = [tex]\frac{-3x-14}{7}[/tex]
Simplfy it. -14/7 = 2 so you get y = -[tex]\frac{3}{7} x - 2[/tex]

8m + 5 + 13m – 5 = 42. What is the value of M?
Answer:
m = 2
Step-by-step explanation:
8m + 5 + 13m - 5 = 42
The 5s cancel each other out
8m + 13m = 42
21m = 42
Divide both sides by 21
m = 42/21
m = 2

Answer:
-i.
Step-by-step explanation:
Applying DeMoivre' s theorem:
(sin 30 + i cos 30)^18
= sin(18*30) + i cos(18*30)
= sin 540 + i cos 540
= sin (3*180) + i cos (3*180)
= 0 + -1 * i

True
False
Can you guys help me with this question.
Answer:
y=2x
Step-by-step explanation:
The equation equals the change in Y over the change of X. If you notice on the table, the x value increases by a unit of 1, and the y value increases by a unit of 2. If you put those two units into the equation of the change in Y/the change of X you will get 2/1=2. The slope is 2. Now plug in the two into y=mx+b form and you will get y=2x. You can check this by taking any y value on the table, multiplying it by 2, and verifying that the value matches the corresponding Y value.
