Answer:
9 green peppers and 3 red peppers
Step-by-step explanation:
Lupe's chili recipe makes 12 servings and uses green peppers = 12
Therefore, for 1 serving he uses =
= 1 green pepper
He uses red peppers for 12 servings = 4
for 1 serving he uses =
red pepper
∴ for 9 servings Lupe needs green pepper = 1 × 9 = 9 green peppers
and for 9 servings Lupe needs red pepper =
× 9
= 
= 3 red peppers
Lupe needs 9 green peppers and 3 red peppers for 9 servings
Answer:
The domain of the function i.e. the value of x can be any real number and the range of the function is y > 0.
Step-by-step explanation:
On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and curves up and increases in quadrant 1.
Therefore, as x tends to - ∞, the y-value tends to 0 but not equal to zero and as x tends to +∞, the y-value also tends to +∞.
Hence, the domain of the function i.e. the value of x can be any real number and the range of the function is y > 0. (Answer)
