Answer:
a
Step-by-step explanation:
6^2+8^2=100
sqrt of 100 = 10
Answer:
1) f(x) = x/8 - 7
2) f(x) = 1 - x/3
3) f(x) = 20 - 0.25x
4) f(x) = x + 7
Step-by-step explanation:
f^-1 = 8(x + 7)
x + 7 = y/8
x = y/8 - 7
f(x) = x/8 - 7
f^-1 = -3(x - 1)
y/-3 = x - 1
x = 1 - y/3
f(x) = 1 - x/3
f^-1 = 4(20 - x)
y/4 = 20 - x
x = 20 - y/4
f(x) = 20 - x/4
f(x) = 20 - 0.25x
f^-1 = x - 7
y = x - 7
x = y + 7
f(x) = x + 7
Answer: 570 total calories
Step-by-step explanation:
450 calories in 50 grams of fat
120 calories in 30 grams of protein
120 + 450= 570
Answer:
Step-by-step explanation:
The given equation is
Subtract 2 from both sides and factor by grouping to get:
By the zero product principle:
When
This implies
When
We have
hence x is not defined for all real numbers
