Answer:
6.
Step-by-step explanation:
x/7 - 3/8 = 27/56
Multiply through by 56 , as 7 * 8 = 56 we have:
8x - 3*7 = 27
8x = 27 + 21 = 48
x = 6.

Answer:
Slope of Function B = - Slope of Function A
Step-by-step explanation:
Function A
f(x) = - 2x + 1
This is in the form y = mx+b where m is the slope
The slope is -2
Function B
We have 2 points so we can calculate the slope
(0,-3) and (2,1)
m = (y2-y1)/(x2-x1)
= (1--3)/(2-0)
= (1+3)/(2-0)
=4/2
2
Slope of A = -2 Slope B =2
The are opposites
A. The discriminant is 81. The formula is b^2 - 4ac.
B. 2 answer and both will be rational due to the fact that the discriminant is a perfect square.
C. Solutions are 1/2 and -4. You can find using the quadratic formula.
