an expression that determine the total cost of gym membership for any number of months is 10+19.99(x)
Given that:
cost per month = $19.99
Starting fee = $10
Months = x
So the expression for 1 person will be:
10+ 19.99(x)
thus an expression that determine the total cost of gym membership for any number of months is 10+19.99(x)

You are correct!
90 would be the correct choice, here is why:
use the eqation: $20*30*15%
first times $20*30=600
now, 600 *15%= $90
therefore, your answer is 90 dollars
2.75 it’s the answer 3.00 divided by 8.25 =2.75
-15+7=-8
Adding numbers with different signs makes it subtraction and the answer will have the sign of the bigger number
f(x) has vertex = (- 1, - 5 ) and is a minimum
g(x) has vertex = (2, 3 ) and is a maximum
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
f(x) = (x + 1)² - 5 is in this form with vertex = (- 1, - 5 ) and minimum
to determine if maximum/ minimum
• if a > 0 then minimum
• if a < 0 then maximum
g(x) = - (x - 2)² + 3 is also in vertex form with a < 0
vertex = (2, 3 ) and is a maximum
