Answer:
The drama club bought 35 t-shirt
Step-by-step explanation:
Let
t-shirt = x
Sweatshirt = y
Total cost = $795
They purchase 20 more tshirts than sweatshirts
x = y + 20
The equation is:
12x + 25y = 795
12(y + 20) + 25y = 795
12y + 240 + 25y = 795
37y = 795 - 240
37y = 555
y = 15
Substitute y = 15 into
x = y + 20
x = 15 + 20
x = 35
t-shirt = 35
Sweatshirt = 15
The drama club bought 35 t-shirt
Answer: B

Answer:
The slope of f(x) is equal to the slope of g(x).
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
step 1
Find the slope of the function f(x)
we have the points
(0,-1) and (3,1)
substitute in the formula
step 2
Find the slope of the function g(x)
take two points of the given table
(0,2) and (3,4)
substitute in the formula
step 3
Compare the slopes

therefore
The slope of f(x) is equal to the slope of g(x).
