Answer:
The inverse is x-8
Step-by-step explanation:
g(x) = x+8
y = x+8
To find the inverse, exchange x and y
x = y+8
Solve for y
Subtract 8 from each side
x-8 = y+8-8
x-8 = y
The inverse is x-8

Answer:
Step-by-step explanation:
There are 2 cups in 1 pint.
Sara gets 2 * 7 = 14 cups
She pays 20 dollars.
Tatiana buys 15 1/2 cups for 20 dollars. In effect, Tatiana got 1.5 cups free, so she got the better deal.
<span>2r + 3s= 9 <=> -6r -9s = -27;</span>
<span>3r + 2s= 12 <=> 6r + 4s = 24;
=> 0*r -5*s = -3 => s = 3/5;
2*r + 3*(3/5) = 9<=> 10*r + 9 = 45 <=> 10*r = 36 => r = 18/5;
