Answer:
(x, y) = (3, 26)
Step-by-step explanation:
I like to solve systems of equations like this by graphing. A graphing calculator easily shows the solution for both x and y.
(x, y) = (3, 26)
__
As an alternative, here, the equations can be subtracted.
y = f(x)
y = g(x)
0 = f(x) - g(x) . . . . subtract the second equation from the first
0 = 11x -7 -(3x +17)
0 = 8x -24 . . . . simplify
0 = x -3 . . . . . . .divide by 8
3 = x
Now, we can substitute into either equation:
y = g(x) = 3(3) +17 = 26
The solution is (x, y) = (3, 26).
the total area of the figure A = 144.5 cm²

How to find the area?</h3>
First, the area of a rectangle of length L and width W is:
A = W*L
Here we have:
L = 13cm
W = 9cm
Then the area is:
A = 9cm*13cm = 117 cm²
For a triangle of height H and base B, the area is:
A = B*H/2
Here the base measures 11cm, and the height is:
H = 13cm - 8cm = 5cm
So the area of the triangle is:
A= 5cm*11cm/2 = 27.5cm²
Then the total area of the figure is:
area = 27.5cm² + 117 cm² = 144.5 cm²

Answer:
Fran's balance will be $866.73.
Step-by-step explanation:
She has an existing balance of $752.69
Her current card charges her a transfer fee of 12.5%, added to her balance, for transferring her debt.
This becomes:
Total is :
The new card has an opening fee of $50, which is also added to her balance.
This becomes now =
She will also have to make an immediate minimum payment, which is 3.35% of her total balance.
This amount is =
Now balance in her account is =
So, Fran's balance will be $866.73.
I hope this helps you
-8x+2. (4x+6)@=12
-8x+8x+12=12
12=12
0=0
Its B I'm sure :), welcome..
