Answer: 123
Step-by-step explanation:
Answer:
f(x) = -7x + 1
Step-by-step explanation:
Slope intercept form is
y = mx + b
m is slope
b is y-intercept
--------------------------
y decreases by 7 for each increase of 1 in x
slope = -7
to find "b" plug in one of the points and m = -7
using point (3, -20)
y = mx + b
-20 = -7(3) + b
-20 = -21 + b
b = 1
The equation is
f(x) = -7x + 1
65/100 or 13/20
Both work, it's just that 13/20 is simplified
Answer:
x2 - 4x - 5 factored form is (x - 5)(x + 1)
