Answer:
Blue - y=-2
Red-
Parallel to Red-
Perpendicular to Red-
Step-by-step explanation:
The slope intercept of a line is y=mx +b where
- m is the slope which is calculated as the vertical distance divided by the horizontal distance between two points.
- b is the y-intercept for value on the y-axis for which the line crosses it.
The Blue line intercepts the y-axis at -2 so b=-2. It has no vertical change since it is a horizontal line. This means the slope, m, is 0. m=0. It's equation is y=0x-2
y=0-2 since anything times 0 is 0.
y=-2.
The red line intercepts the y-axis at 2 so b=2. It intercepts the x-axis at (-3,0). Between these two intercepts we can find the slope:
Slope:
We substitute and
The red line has equation .
Parallel lines have the same slope with a different y-intercept. So we write a line where m=2/3 and b is something else.
Perpendicular lines have a negative reciprocal slope to the original. So we write the line where m/-3/2.
1st step, divide both sides by 4
2nd step, move 2 to the right side and change the plus to a minus
3rd step, subtract the numbers
the answer is x=4 I did the work i dont know if it helped but I hope it did. also, sorry for my handwriting I was rushing
The value of x is 113 because the 3 angles in a triangle add up to 180° so 180 subtracted by 28° and 39° gives the value of angle x.
The value of y is 67° because x and y are supplementary angles which means they add up to 180°. So 180-113 gives y.
The value of z is 49° because if you subtract the 180° that makes up the triangle from 67 and 64, you get 49.
we have the equation
2(x-4)=6x+4
solve for x
Apply distributive property left side
2x-2(4)=6x+4
2x-8=6x+4
Group terms
6x-2x=-8-4
combine like terms
4x=-12
divide by 4 both sides
x=-12/4
<h2>x=-3</h2>
