Answer:
<em>1 and 9</em>
Step-by-step explanation:
<u>Common Solutions to Functions</u>
Let f(x) and g(x) be any type of function. When we need to find values of x such that f(x)=g(x), we usually set up the equation for each of them and solve it for x by any available algebraic or approximate method.
In this situation, we are not given the explicit expression of any of the functions, but the table of values for each one of them. We have to take a look of the values of x for which f and g are the same.
A closer look at the table reveals that f(x)=g(x) for two values of x:
for x=1, f(1) = 14 , g(1) = 14
for x = 9, f(9) = 6, g(9) = 6
The answers are 1 and 9
Answer:
I say C is your best answer because it might be a typo
First you have to find the area of the triangle ( 4 + 6 = 7.2) then you have to subtract that area from the area of the rectangle ( 66 - 7.2 = 58.8). The answer is 58.8
At the bank, Derek made 7 withdrawals, each in the same amount. His brother, John, made 5 withdrawls, each in the same amount.
Let x be the amount of one of Derek's withdrawals
Each of John's withdrawals was $5 more than each withdrawal that Derek made.
x + 5 is t the amount of one of John's withdrawals
Derek made 7 withdrawals
So amount withdraw 7 times = 7x
John made 5 withdrawals
So amount withdraw 5 times = 5(x+5)
Both Derek and John withdrew the same amount of money in the end
(A)7x = 5(x+5)
(B) Solve for x
7x = 5x + 25
Subtract 5x from both sides
2x = 25
Divide by 2
x = 12.5
(C) check your solution
we plug in 12.5 for x in 7x= 5x + 25
7(12.5) = 5(12.5) + 25
87.5 = 62.5+ 25
87.5 = 87.5
(D) Each brother withdrawal 87.5 dollars
