Answer:
40
Step-by-step explanation:
Going from left to right
We need to find the angle from the first triangle
The sum of the angles of a triangle is 180
80+25+x = 180
Combine like terms
105+ x = 180
Subtract 105 from each side
105-105+x = 180-105
x = 75
Then we have 3 angles that make a straight line and a straight line is 180
x + 50 + y = 180
75+ 50 + y = 180
Combine like terms
125 + y = 180
Subtract 125 from each side
125-125+y = 180-125
y = 55
We now have the triangle on the right
The angles add to 180
55+85+ ? = 180
Combine like terms
140+ ? = 180
Subtract 140 from each side
140+? - 140 = 180-140
? = 40
I’m not totally sure about the less and greater signs because I’m not sure you can graph using those signs but either way their are your line equations
x+4
___________
(x+2)|(x^2+6x+9)
-x^2-2x
__________
4x+9
-4x-8
__________
1
so the quotient is:
(x+2)(x+4)+1/(x+2)
A parallel equation (when graphed) will have the same slope, but a different y-intercept.
As long as you keep y = -
x + b, you can input anything for b to solve this question.
Given:
y = -x - 5
Equation of a parallel line:
y = -x + 6, y = -x + 1,356, y = -x - 8, etc
Example answer you can use:
y = -x - 8
