Answer:
the first option
Step-by-step explanation:
(f-g)(x) simply means to subtract both expressions. really literally.
and we go through it power by power of x.
the highest power/exponent of x is 3 (x³). only f(x) has one.
so, -7x³ is the first part of f-g.
next is x².
11x² - 6x² = 5x², which is the second part of f-g.
next is x.
-8x - (-14x) = -8x + 14x = 6x, which is the third part of f-g.
next is x⁰ (in other words, no x, just a constant).
4 - (-3) = 4 + 3 = 7, which is the 4th part of f-g.
we have no x to the power of -1 or -2, so we have -3
0 - (-4x‐³) = 4x‐³, which is the last part of f-g.
so, it is clearly the first answer option.
Answer:
I think it would be 11.2
Step-by-step explanation:
because if I is 10 and it only goes across to the other side then it would only be 11.2
Answer: C. 2
Step-by-step explanation:
Subtract the y coordinates over the subtraction of the x coordinates
(3 - 7) / (3 - 5)
-4 / -2 = 2
The point-slope form of a line:
We have:

Answer: she has $20 left now.
Step-by-step explanation:
The total amount of money that Kathryn had yesterday was 105 dollars.
She first spent 1/3 of it at the mall. This means that the amount of money that she spent at the mall is
1/3 × 105 = $35
The amount left after her shopping would be 105 - 35 = $70
Later, she went to the movies and spent 5/7 of what was left after her shopping. This means that the amount of money that she spent at the movies is
5/7 × 70 = $50
The amount that she has left now is
70 - 50 = $20
