Hello!
ANSWER:
The selling price would be $380.80.
Convert the percentage to a decimal by dividing it by 100.
36% ÷ 100 = 0.36
Find 36% of the cost of the TV:
280 × 0.36 = 100.8
Add:
280 + 100.8 = 380.8
-0,5=-1/2
-1/2•(-2)=1
The answer is 1
Answer:
The minimum value = -38
Step-by-step explanation:
∵ f(x) = x² - 12x - 2
∵ -12x ÷ 2 = -6x ⇒ -6 × x
∴ (x - 6)² = x² - 12x + 36
∴ Add and subtract 36 in f(x)
∴ f(x) = (x² - 12x + 36) - 36 - 2
∴ f(x) = (x - 6)² - 38 ⇒ completing square
∴ The vertex of the parabola is (6 , -38)
∵ Its minimum point because the coefficient of x² is positive
∴ The minimum value = -38
Answer:
Step-by-step explanation:
x is the number of GB
f(x) is the cost in dollars
f(x) = 10x
Bill for 6 GB = f(6) = 60
:::::
f(x) = 8x+15
Bill for 8 GB = f(10) = 95
:::::
f(x) = 5x+30
Bill for 2 GB = f(2) = 40
Answer:
It's nine plus negative three
