Answer:
Cory bought 6.47 gallons
rate of change is $2.78 per gallon
Step-by-step explanation:
cost of gas per gallon = $2.78
it means that if one buy 1 gallon he will have to pay $2.78 and similary for each increase in 1 gallon of gallon gas he will have to pay $2.78.
Thus, rate of change is cost of gas per gallon as cost to buy gas changes with the change in quantity of gallon.
Let the quantity of gas bought be x gallon.
Total cost for x gallons = cost of gas per gallon*x = 2.78x
Given that total money paid by him is $18
2.78x = 18
x = 18/2.78 = 6.47
Thus, Cory bought 6.47 gallons
rate of change is $2.78 per gallon
Answer:
y=6^x-2
Step-by-step explanation:
Start with the parent function, a^x. The graph looks like it has been translated b units down, so our function is a^x+b. Now at x=0, y=-2. So b=-2. Next at x=1, y=3. 3=a^(1)-2, a=6. y=6^x-2 is the equation
Answer:
2/12
Step-by-step explanation:
Because there are 6 tile total but he wants two put 2 numbers out of the bag twice..... you get the 12 because he pulls a number out twice and since he has 6 and then does it again it adds to 12 so the answer would be 2/12
<u>Answer:</u>
<h3>(
) x (
) </h3>
<u>Step-by-step explanation:</u>
To find the area of a rectangle, we have to multiply the length with the width.
In the question, the given length is 'x' and the width given is 'x +7'
So, the area would be
( ) x ( )
The area = 
So, the equation to find the area of such a rectangle would be:-
( ) x ( )
41. Degree 3 = x^3 (maximum power in the equation)
Zeros: -1, 1, 3
(x-1)(x+1)(x-3)=f(x) <--- expand as necessary
44. Zeros: -4, 0, 2
(x+4)x(x-2)= f(x) <--- expand as necessary
47. Multiplicity is how many times a particular number is 0 for a given function.
(x+1)(x-1)^3(x-2)^3 <-- not too sure about this one, google definition of multiplicity?
Hope I helped :)
