Hi there!
First we need to calculate how much the 3 T-shirts cost and subtract that from the amount she paid to find the change.
First, we multiply to find the coats of the T-shirts.
3 × 8 = 24
Now, we subtract 24 from 50.
50 - 24 = 26
So, she got $26 of change.
Hope this helps!
ANSWER

EXPLANATION
The given equation is

Divide both sides by


Cancel out common factors on the left hand side,

For this solution to be a whole number, then

should be a factor of

.
The reason is that, factors of 6 will divide exactly in to 6 without a remainder, making the answer a whole number.
The whole numbers that are factors of 6 are,

Note that, the set of whole numbers are,
{

}
Answer: Managers in a corporate setting tend to view decision making differently than ... to each possible outcome (a formal representation of this is known as a decision tree ). ... Such principles, when used in decision making, can help the organization ... enabling users to translate raw data into a form useful for decision support.
Step-by-step explanation: google
Te x intercepts are where the graph crosses the x axis or wher y=0
the y intercept is where the graph crosses the y axis or where x=0
to find vertex, here is a hack
the x coordinate of the vertex for an equation in form ax^b+bx+c=y is -b/2a
so
y=3x^2+12x+7
-b/2a=-12/2(3)=-12/6=-2
sub that back
y=3(-2)^2+12(-2)+7
y=3(3)-24+7
y=9-17
y=-8
vertex is (-2,-8)
intercepts
x intercept is where y=0
0=3x^2+12x+7
using quadratic formula
x=(-6-√15)/3 and (-6+√15)/3
xints at ((-6-√15)/3,0) and ((-6+√15)/3,0)
yint is where x=0
set x=0
y=7
yint is at y=7 or (0,7)
vertex at (-2,-8)
xints at x=

and

or at the points

and

yint at y=7 or at (7,0)
