Answer:
a=-16, b=11, c=23
Step-by-step explanation:
The function whose table is drawn is
To find the value of a, we substitute x=-5.
To find the value of b, we substitute x=4.
To find the value of c, we substitute x=8,
Non Residents:
f(x)= money in $ paid.
x=number of days.
f(x)=x(12+3.5)=15.5 x
f(x)=15.5x
Arkansas residents
f(x)=money in $ paid.
x=number of days.
f(X)=x+174
Now, we equate functions:
15.5x=x+174 (this is the equation)
15.5x-x=174
14.5x=174
x=174 / 14.5=12
Answer: the number of days is 12 days. The ecuation has one solution, because when I has solved it, I have had one solution.
Answer:
The value of x is 49 and the value of AB is 90
Step-by-step explanation:
You know that AB and DE are congruent. That information is given to you.
You set the equations equal to each other and then solve.
2x - 8 = x + 38
Subtract x
x - 8 = 38
Add 8.
x = 49
Plug back into 2x - 8 to find the value of AB
2 times 49 - 8
98 - 8
90
Answer:
$2.25
Step-by-step explanation:
You can find the answer by setting up a simple equation.
Brand X is 1.65 for 11 ounces
we can find the cost of one ounce of Brand X by using division
1.65/11
.15
this means that for every ounce of Brand X, it costs 15 cents
Since brand Y costs two cents more per ounce that would make it be 17 cents per ounce
now all you need to do is multiply and solve.
.15 * 15 = $2.25
