Answer:
D. f(-3) = 11
Step-by-step explanation:
When f(x) is divided by x+3, you get a quotient g(x) and a remainder of 11:
f(x) / (x + 3) = g(x) + 11 / (x + 3)
Multiply both sides by x+3:
f(x) = g(x) (x + 3) + 11
Substitute -3 for x:
f(-3) = g(-3) (-3 + 3) + 11
f(-3) = g(-3) (0) + 11
f(-3) = 11
A = 1/2 x bh
A = 1/2 x 5 x 12
A = 6 x 5
A = 30m
The answers are:
<span>ƒ(x) = x - .15x
</span><span>Sale = Original - .15(Original)
</span><span>y = .85x
Let sale price be f(x) and x be the original price. Discount was 15% = 0.15
f(x) = x - 0.15x
If f(x) is sale and x is the original, then:
</span><span>Sale = Original - .15(Original)
Let sale price be y and original price x:
y = x - 0.15x
y = 1 * x - 0.15 * x
y = (1 - 0.15) * x
y = 0.85x</span>
