Answer:
Intercept = - 3 ; slope = 18
Step-by-step explanation:
Given the points :
(3, 51) ; (5, 87)
x1 =3, y1 = 51, x2 = 5 ; y2 = 87
Slope intercept relation:
y = mx + c
m = slope ; c = intercept ; x and y are x, y vlayes respectively
Slope (m) = (y2 - y1) / (x2 - x1)
Slope (m) = (87 - 51) / (5 - 3)
Slope = 36 / 2
Slope (m) = 18
The intercept c :
m = 18 ; x = 5 ; y = 87
Substitute values into the slope intercept formula :
87 = 18(5) + c
87 = 90 + c
c = 87 - 90
c = - 3
Intercept = - 3
If we multiply 8 and 7 we get the answer:
8 x 7 = 56
Now we are going to break apart the number in such a way that we still get the answer 56.
we can split 8 into 2 equal parts 4 and 4, so
8 = 4+4
but 7 cannot break apart in equal part so,
(4+4) x 7 = 56
we can also add 7, 8 times or add 8 7 times and still get the answer 56,
7+7+7+7+7+7+7+7=56
8+8+8+8+8+8+8 = 56
Answer:
x = 4
Step-by-step explanation:
4(2x+9) = 68
8x+36 = 68
8x = 68 - 36
x = 4
