Answer:
Slope = 3
y-intercept = (0, 11) or 11
Step-by-step explanation:
Every time x goes up by 1, y goes up by 3, so the slope is 3.
To find the y-intercept, you look at what y is when x = 0. In this case, it's 11.
Answer:
x = 3 and x = 4
Step-by-step explanation:
3x - 4 + 4x - 8 = x^2
7x -12 = x^2
x^2 - 7x + 12 = 0
(-4)*(-3) = 12 and (-4)+(-3) = -7
(x-3)(x-4) = 0
x - 3 = 0. x = 3
x - 4 = 0. x = 4
Answer:
8 times 5 is 40
8 plus 32 is 40
21 divided by 3 is 7
21 minus 14 is 7
E makes no sense becayse you cant multiply 21 by anything to get 7
Step-by-step explanation:
Answer:
Step-by-step explanation:
11 no
46+4x=90 degree(being perpendicular)
4x=90-46
x=44/4
x=11
12 no
They are complementary angles
6 no
angle B+27=180 degree(being straight line)
angle B=180-27
angle B=153
10 no
angle 38 +angle DFE=180 degree(being supplementary)
angle DFE=180-38
angle DFE=142 degree
5 no
They are vertically opposite angles.
7 no
angle AGF and angle CGD (because they have common arm and vertex)
