Answer:
y=19
Step-by-step explanation:
3(y - 9) = 30
3y - 27 = 30
3y = 30 + 27
3y = 57
y = 19

The answer could be something of the sort like 2/24, because 1/12 can't be simplified, you would just keep multiplying both numbers until you get another fraction equal to 1/12

Step-by-step explanation:
Guess and Check:
$80.00*15=$1,200
$165.00*10=$1,650
$1,200+$1,650=$2,850.
15 of the pairs of shoes are Jordans, while 10 of the pairs are Adidas.
Answer:
The minimum value of this function is -40.
Step-by-step explanation:
Recall that the minimum of a quadratic whose graph is a parabola that opens up, as this one does, is the vertex of the graph. The x-coordinate of the vertex is given by x = -b / (2a), where a is the coefficient of the x^2 term and b is that of the x term.
Here, x = -12 / (2*2), or x = -12/4, or x = -3.
Find the y-value at this x-value: f(-3) = 2(-3)^2 + 12(-3) - 22, or
f(-3) = 2(9) - 36 - 22, or -40.
The vertex is at (-3, -40). The minimum value of this function is -40.
