Answer:
(ax+9)-(4x+b)
Step-by-step explanation:
Youre trying to find the difference, how much shorter the base is. The base is (4x+b) and the side is (ax+9)
Therefore, you subtract the base from the side, being (ax+9)-(4x+b)

For this case, we must find the equation of the line.
The generic equation of the line is:
The slope of the line is:
Substituting values we have:
Rewriting:
We now choose an ordered pair:
(xo, yo) = (0, 12)
Substituting values we have:
Rewriting the equation:
For 20 visits, we evaluate the equation when x = 20.
We have then:
Answer:
The discounted entrance fee is 1.5$. The total cost is 42$ after 20 visits
Just use photo math, it gives you the answer and explains it
Step-by-step explanation:
1) 3^5 × 3^3 = 3^(5+3) = 3^8
=> 3^5 × 3^3 = 3^8
2) 3^3 × 5^3 = (3×5)^3 = 15^3
=> 3^3 × 5^3 < 15^5
3) 3^5 × 5^3 = 3^2×(3^3 × 5^3)
= 3^2 × 15^3 = 9×15^3
=> 3^5 × 5^3 > 15^3
I'm assuming this is a system of equations you want solved so,
x = -y + 3
-2(-y+3)+4y = 6
2y - 6 + 4y = 6
6y = 12
y = 2
x + 2 = 3
x = -1
(-1,2)
