X = -2, -4y = -2- 18 , -4y = -20, so y = 5
x = -1, -4y = -1 - 18 , -4y = -19, so y = 4.75
x = 0, -4y = -18, so y = 4.5
x = 1, <span>-4y = 1- 18 , -4y = -17, so y = 4.25
</span>x = -2, -4y = 2- 18 , -4y = -16, so y = 4
you can use three of above points to graph your equation
Answer:
17 gallons of gas
Step-by-step explanation:
divide 36.21 (the total amount paid) by 2.13 (cost per gallon). This will give you 17 gallons of gas.
Answer:
The domain is (-3,∞)
and the range is from (-∞,∞)
Step-by-step explanation:
Remember, the domain is the values on the x-axis (from left to right) while the range is all of the values on the y-axis ( top to bottom). The x-values don't start until -3 which is why that number comes first. The other values keep going indefinitely to the right which is why there's an infinity sign. The range of y values is also indefinite because there are arrows going on infinitely up and down so it would be (-∞,∞)
Answer:
opiton b
Step-by-step explanation:
To find out which equation satisfies h(x) we need to check with each option
We plug in x value
A) h(–1.25) = –0.5
Plug in -1.25 for x in h(x) = 16^x
That is not true
B) h(–0.5) = 0.25
Plug in -0.5 for x
That is true.
C) h(0.75) = 12
Plug in 0.75 for x
That is not true.
D) h(1.25) = 20
Plug in 1.25 for x
That is not true
Answer:
t = (m / g) * p
Step-by-step explanation:
Since we are given a variable for every part of the equation that we need we can go ahead and create the following equation where t equals the total cost
t = (m / g) * p
In this equation, we need to first divide the total number of miles by the number of miles that the car gets per gallon. This would give us the total number of gallons that the car would use during the entire trip. We then multiply the number of gallons by the price per gallon to get the final cost of the entire trip.
