We are considering the function

the graph of this function is the graph of the parent function

after applying the following steps.
1. multiply by -1:

is

reflected with respect to the x-axis.
2. multiply by 5:

is

shrinked towards the y axis.
for example, consider x=1/2

now this means that

is "lower" than

, which means there is a shrinking of the graph.
3. add 5:

is

shifted 5 units up.
4.
so the graph of the function a) opens down, b) is shifted 5 units up, c) is not wider than the parent function
Answer: False

Answer: 400
Step-by-step explanation:
If 5% of a number is 80, just multiply that number by 5 to get 25 (5 x 5 = 25) and you will get 400.
Answer:
15C is 59F
Step-by-step explanation:
As an equation, F = (1 4/5)C + 32. 1 and 4/5 is the same as 9/5.
Substitute 15 for C.
F = (9/5)C + 32
F = (9/5)(15) + 32 Multiply 15 by the top number in 9/5
F = 135/5 + 32 Convert 32 to a fraction over 5
F = 135/5 + 160/5 Add the numerators under the same denominator
F = 295/5 Divide
F = 59 Degrees in Farenheit
Therefore 15°C is 59°F.
Answer:
c. 25 minutes
Step-by-step explanation:
3x + 10 = 85
3x = 85 - 10
3x = 75
x = 25
