Answer:
11
Step-by-step explanation:
-4x + 7 ; x = -1
-4x (-1) + 7
4 + 7 = 11
Answer:
Your first step in solving the system would be to substitute the value of a variable into one of the equations
Step-by-step explanation:
We know that x = 2y + 2 and y = -1/3x + 4, so we could insert one of these values as the variable in one of the equations
If we were to insert -1/3x + 4 for y, our new equation would be:
x = 2(-1/3x + 4) + 2 (as you can see, the value of y was inserted into the equation)
Answer:
-5
Step-by-step explanation:
4x0.5=2
2x0.5=1
2+1=3
3-8=-5
Answer:
B.
Step-by-step explanation:
Every answer besides B. has an input that repeats. A function contains inputs that have exactly one output. This means x values cannot have more than one y value.
