a
10.95x + 2.50, but for eight books so 10.95 x 8 + 2.50 = 90.10
b
12.50x + 4.50, but for six books so 12.50 x 6 + 4.50 = 79.50
c
To do this, we can set them both equal to each other and if x is a whole number of books, then they do pay the same amount. If x is a decimal, then they don't pay the same amount.
10.95x + 2.50 = 12.50x + 4.50
2.50 - 4.50 = 12.50x - 10.95x
-2 = 1.55x
This can never be a whole number, so therefore members and non-members can never pay the same amount for an order of x books.
Answer:
Step-by-step explanation:
x = domain, f(x) = range
<u>Look for matching numbers:</u>
- f(4) = 1/2
- f(x) = 4 when x = 8
Answer:
50
Step-by-step explanation:
(2+3=5) +5 = 10
6+7 = 13
8+9=17
10
Then add them all together:
10+13+17+10=50
Answer:
x= (-2, 0) y=(0, -5)
Step-by-step explanation:
or you could say -2 and -5
Answer:
y = x² - 10x + 41
Step-by-step explanation:
The standard form of a quadratic is ax² + bx + c : a ≠ 0
Given
y = (x - 5)² + 16 ← expand (x - 5)²
= x² - 10x + 25 + 16
= x² - 10x + 41 ← in standard form
