Answer:
(a) 40 into 1120=28....28 into 1120=40 so 1120 is the denominator of 40&28
Y = x² - 5x + 2
y = -6x + 4
-6x + 4 = x² - 5x + 2
0 = x² - 5x + 2 + 6x - 4
0 = x² + x - 2
(x + 2)(x - 1)
x = -2 ; x = 1
y = x² - 5x + 2 ; x = -2 y = x² - 5x + 2 ; x = 1
y = (-2)² - 5(-2) + 2 y = 1² - 5(1) + 2
y = 4 + 10 + 2 y = 1 - 5 + 2
y = 16 y = -2
y = -6x + 4 ; x = -2 y = -6x + 4 ; x = 1
y = -6(-2) + 4 y = -6(1) + 4
y = 12 + 4 y = -6 + 4
y = 16 y = -2

30 pi inches divided by the one fifth angle is gonna be 6
Answer:
7x = y + 37
Step-by-step explanation:
y = 7x - 9
Differentiating y with respect to x, we have as follows:
dy/dx = m = 7 ( where m is the slope)
Using the formula y - y1 = m(x - x1) to obtain the equation of line passing through point (4.-9)
y + 9 = 7(x - 4)
y + 9 = 7x - 28
∴ 7x = y + 37
