Step-by-step explanation:
y = -9x - 45 -5
y = -9x - 50
slope = x coefficient = -9
we can use the point where
x = 0
y = -50
P1 (0, -50)
and when y = 0
-9x = 50
x = -50/9
P2 = (-50/9 , 0)
Answer:
Question 2
x is approximately 15.038 or 15 days
Question 3
$3.41
Question 4
31.1
Step-by-step explanation:
Question 2
5.2 km/1 day =78.2 km/x days
Multiply both sides by x
5.2x=78.2
divide by 5.2
x is approximately 15.038
or 15 days
Question 3
350-(262.94+83.65)
$3.41
Question 4
22(1.3)+2.5
31.1 m
The slope for y=5+3x is 3
I believe it is 1. Function 2. Not a function 3. Function 4. Not a function. I hope this helps! :)
