Answer:
11 calls
Step-by-step explanation:
She has already spent 42 min. Also she wants to talk for 2 min per call. We can change calls on x. So, only 2x min for her calls left.
42 + 2x = 64
2x = 64 - 42
2x= 22
x=11
Answer: 11 calls

so C E and F
Step-by-step explanation:
Just simplify?
Than your answer should be
Answer: [c, ∞)
<u>Step-by-step explanation:</u>
Range is all of the y-coordinates.
The parabola is upright (∪) because the coefficient of x² is positive.
So the minimum value is at "c" and the parabola tends toward infinity.
Range: y ≥ c <em>in Interval Notation</em>: [c, ∞)
