Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
Step 1: Define
f(x) = -3x + 5
f(x) = -4
Step 2: Substitute and Evaluate
-4 = -3x + 5
-9 = -3x
x = 3
Answer:
Please see the attached picture.
Answer: B.no
Step-by-step explanation:
To figure this out, plug (1, -4) into the equation y=-2x. 1 is the x value, so we plug it into the x. -4 is the y value, so we plug it into the y spot. In the end we get -4=-2(1). Is this true? No, it isn't. Therefore it is not an answer
