Answer:
f(-5) = -16
Step-by-step explanation:
f(x)=2x-6
f(-5) = (2 * -5) -6 = -10 - 6 = -16 ... replace x with -5
This is what i would do i would do this is every student has 40 then 1 student has 40 then he gets a movie ticket so 40 - 5 = 35 then he buys candy for 7.50 so 35 - 7.50 = 27.5 then buys a 2 dollar trolley ride so 27.5 - 2 = 25.5 so every student was left with 25 dollars and 5 cents
i think 10 more miles.
70/7=10
which means he gets 10 more miles for every gallon of fuel
6:14 + 2 hours = 8:14
8:14 + 20 minutes = 8:34
8:34 + 8 minutes = 8:42

Answer: a) What is a good scale to use for the y axis? -20 units.
(b) What is a good interval to use for the y axis?- 20 units
Step-by-step explanation:
A family is tracking its spending habits. Over the
past year, the grocery bill has ranged from $120 to $180.
We need to plot these points on a coordinate grid.
If we plot the grocery bills along the y-axis, and past years will be plotted along the x-axis.
So, a) Good scale to use for the y-axis will be
1 scale = 20 units
As 120 and 180 are both divisible by 20.
So, it will be a good scale to use for the y-axis.
b) Good interval to use for the y-axis:
It will be again of 20 units.
