y=-4x+5
Answer:
35
Step-by-step explanation:
So the triangle who posses the angle with measurement k=35 is an isosceles. I know this because there are two congruent legs. Those 2 congruent legs tell us the angles opposite of them are all congruent.
So we know one equation to solve is:
x+x+35=180 where x is the base angle in the left triangle picture.
Combine like terms:
2x+35=180
Subtract 35 on both sides:
2x=180-35
Simplify:
2x=145
Divide both sides by 2:
x=72.5
So one of the base angles of the left isosceles triangle is vertical with with another angle in the right. This triangle on the right is also isosceles.
So we know that 72.5+72.5+h=180.
Combine like terms:
145+h=180
Subtract 145 on both sides:
h=180-145
Simplify:
h=35

Answer:
B.one solution; lines that intersect at one point
Step-by-step explanation:
The slope of the line is 4
The point slope form of the line can be written as (y - 8) = 4(x - 9)
The slope intercept form of the line is y = 4x - 28
In order to find the slope you will need to use the formula for slope. It is included below.
m(slope) = (y2 - y1)/(x2 - x1)
m = (8 - -12)/(9 - 4)
m = (8 + 12)/(9 - 4)
m = 20/5
m = 4
Now that we have the slope, we can plug it into point slope form along with one of the points.
(y - y1) = m(x - x1)
(y - 8) = 4(x - 9)
Now to get to the slope-intercept form of the line, we can simply manipulate the point-slope form until it is in y = mx + b
(y - 8) = 4(x - 9) ----> Distribute the 4
y - 8 = 4x - 36 -----> Add 8 to both sides
y = 4x - 28
