Answer:
20
Step-by-step explanation:
straight line is 180 degrees
110+?=180
?=70
y=90 because it is a right angle
All angles of a right triangle added equals 180
so 70+90=160
180-160=20
x=20
Answer:
3 times faster
Step-by-step explanation:
times faster
Slope intercept form is: y=mx+b
For the other line to be parallel they must have the same slope so:
y=5x+b, using the point (4,5) we can solve for the y-intercept, or "b"
5=5(4)+b
5=20+b
b=-15 so the line is:
y=5x-15
Answer:
18
Step-by-step explanation:
Solve the separate part of the equation first
6(4) 6(-2) would equal 24-12
Add it back in to get: 10 - 4 + 24 - 12
-4-12 and 10+24 are the like terms so
10+24 = 34 and -4-12 = -16
Equation in the end: 34-16
Simplify that to: 34-16 = 18
