Answer:
1. y=3x-1
Step-by-step explanation:
y=mx+b
y=output
m=slope
x=input
b=y-intercept
Answer:
105
Step-by-step explanation:
The interior angle for R is supplementary to the 155 degree angle
(they add to 180)
180-155=25
The sum of the interior angles of a triangle is always 180
180-50-25= 105
Answer:
8 - 
Step-by-step explanation:
For this problem you have to use the 45-45-90 triangle theorem and 30-60-90 theorem.
For 45-45-90, the isosceles sides = 4, so the hypotenuse of the 30-60-90 triangle is 4 times 2, which is 8. If x is 8, then since y is the side across from the 60 angle, y is
. Since this really can't be simplified after y is subtracted from x, the final answer is just 8 -
.
The first one is 19,487,171 and the second is 7,776
