Answer:
A, D, E
Step-by-step explanation:
Time is a function of temperature because there are no points where the x-value has more than one y-value.
There are two points where the temperature reaches 74 degrees.
Between 5 and 9 the temperature did not change.
6x = 16 +14
6x = 30
30 / 6 =5
x= 5
Answer:
D but dont get mad
Step-by-step explanation:
Answer:
7. y= x + 12 8. y= -1 + 4x
Step-by-step explanation:
for 7 all you need to do is subtract x from both sides to get y= 12- x, and to make it perpendicular you need to make the current slope it’s exact opposite so in this case that’s just changing the “-” symbol to an “+”.
for 8 you do the same first step you did in 7 and subtract 4x from both sides to get -y= 1 - 4x. Next you divide everything by -1 (because it’s the number in front of the Y) and you get Y= -1 + 4x
Decreasing [-8, -4] increasing [-1, 2]
(look at the slopes)
