Cross-multiply so that 8(3x + 1) = 14(2x)
Distribute the 8 and 14 into the parentheses:
24x + 8 = 28x
Subtract 24x from both sides:
8 = 4x
Divide both sides by 4:
x = 2
Answer:
d
Step-by-step explanation:
Slope intercept form: y = mx + b
y = -x + 7
x + y = 21
x + y = 21
-x -x
y = -x + 21
y = -x + 7
y = -x + 21
Parallel lines have the same slope. Here, our slope is -1
Therefore, our final answer is d.
Hope this helps!
Answer:
Step-by-step explanation:
The y intercept only occurs when x=0 so (0,0) is the only y intercept of those choices.
<em>*Remember that y and f(x) are the same.</em>
With f(2), you are solving for the output (y), given that the input (x) is equal to 2.
With f(x) = 2, you are solving for the input (x), given that the output (y) is equal to 2.
