Answer:

How you can tell

Step-by-step explanation:

A function assigns exactly one output to each input: x/input y/output

How they work: X <u>can not repeat</u> but Y <u>can</u>.

Lets see your problem, there are no inputs repeating and the outputs are fine.

That is a function!

The middle school basketball team is selling t-shirts for $12.50 each to raise money for new uniforms. They have already sold 40
Rama09 [41]

Step-by-step explanation:

given:

$12.50- the price of the tshirts

40- the tshirts they have sold

$850- the raise they need

solve:

$12.50 × 40 = $500 (the price of tshirts and tshirts they have sold)

$850 - $500 = $350 (the raise they need and the money they have so far from the 40 tshirts they have sold)

$350 ÷ $12.50 = 28 (the money they lack and the price of a tshirt)

answer:

thus, they need to sell 28 more tshirts to have the raise of at least $850

hope this helps, good luck! :)

The sum of two integers is 121. The larger integer is 7 more than twice the smaller integer. Find the two integers.
iren [92.7K]
X + (2x + 7) = 121 : Write the expression.
3x + 7 = 121 : Combine like terms.
3x + 7 - 7 = 121 - 7 : Isolate x.
3x = 114 : Combined like terms.
3x / 3 = 114 / 3 : Find the value of x.
x = 38 : This is the smaller integer.
(2x + 7) = (2(38) + 7) = 76 + 7 = 83. : Find the value of the larger number by plugging in the value of x to the larger number's quantity.
The larger number is 83, and the smaller number is 38.
