Answer:
x=20; vertical angles theorem
Step-by-step explanation:
hi! we can use the vertical angles theorem for this. vertical angles are congruent to each other, meaning they are the same amount of degrees. so, we can set 2x+10 and 50 equal to each other.
2x+10=50
2x=40
x=20
x=20 because of the vertical angles theorem.
3x - 2y = 5 is linear
linear equations will not have exponents
Step-by-step explanation:
81
I think this should be the answer
Answer:
We can use excel regression data analysis tool to find the equation of the regression line that best fits the data.
The excel output is attached here.
Therefore, the equation of the linear regression is:

Where:
21.9028 is the intercept and 1.5736 is the slope.
Dimensions of the logo:
W = 4 in, L = 6 in
Dimensions of the billboard:
W ( Billboard ) = 4 x 15/2 = 2 x 15 = 30 in
L ( Billboard ) = 6 x 15/2 = 3 x 15 = 45 in
Answer:
D ) 30 in by 45 in
