I am assuming by -x2 - 4x you mean
.
if so when plugging in
you get
so the answer is C
Answer:
Step-by-step explanation:
x2 − 9x + 20
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
Inequality Form:
x < 9
Interval Notation:
(-∞
,9)
To be parallel, this new line has to have the same slope as the other. To find the slope, we look at the number multiplying x.
-x means x is being multiplied by -1, so the slope, or m, is -1.
y = -x + b
Now, input the coordinate point and solve for b.
-2 = -1(2) + b
-2 = -2 + b
Add 2 to both sides.
0 = b
y = -x
Answer: C: 12/5
Step-by-step explanation:
y intercept is where x is 0, so set x equal to 0
0+5y=12
y=12/5
