Answer:
1
Step-by-step explanation:
note (g - f )(a) = g(a) - f(a)
g(a) - f(a)
= 2a + 4 - (a - 4)
= 2a + 4 - a + 4
= a + 8
Thus
(g - f)(- 7) = - 7 + 8 = 1
We know that both lines will be equivalent, so to solve for x we can equate the two expressions
5x = 2x + 63
We will first subtract 2x from both sides
3x = 63
We will then divide both sides by 3
x = 21
I think it’s 20d-$12
Hope this helps!
Answer:
It represents the one-time campaign fee 500.
Step-by-step explanation:
A company is paying a local television station to run its commercials. The cost of running commercials is a one-time campaign fee and also a per-second fee for the air time of each commercial. The cost can be modeled by the equation y = 500 + 50x, where x is seconds.
The equation is in the slope-intercept form and the y-intercept is 500.
Now, it represents the one-time campaign fee 500. (Answer)
