Answer:
x = 47
Step-by-step explanation:
The exterior angle is the sum of the opposite interior angles for a triangle
2x-2 = x + 45
Subtract x from each side
2x-2 -x = x+45-x
x-2 = 45
Add 2 to each side
x-2 +2 = 45+2
x = 47

Answer:
y-intercept is the value of y when x is equal to zero. Because the y intercept is a point on a graph, you'll usually write it in point/ coordinate form.
Step-by-step explanation:
The y-intercept is where the parabola of a function crosses (or intercepts) the y axis.
Answer:
(21, 17 )
Step-by-step explanation:
Using the midpoint formula and equating to the coordinates of the midpoint.
Let endpoint 2 have coordinates (x, y ), then
0.5(x - 3) = 9 ( multiply both sides by 2 )
x - 3 = 18 ( add 3 to both sides )
x = 21
and
0.5(y - 5) = 6 ( multiply both sides by 2 )
y - 5 = 12 ( add 5 to both sides )
y = 17
endpoint 2 = (21, 17 )
Given a = 3 and b = - 8 ,
= > 2b² - 4a + 4a²
= > 2( - 8 )² - 4( 3 ) + 4( 3 )²
= > 2( 64 ) - 4( 3 ) + 4( 9 )
= > 128 - 12 + 36
= > 116 + 36
= > 152
