Answer:
3rd option. The way you do it is just plug in negative x value let's say -8, plug it in then y would be a positive value. So that rules out first two options. Then plug in positive x value, y would be negative.
Positive correlation means that if x goes up then y goes up, negative correlation means that if x goes up then y goes down. Since both x and y are increasing each time, it is positive.
Answer: 0
First: Move constant to the left by adding its opposite to both sides
-3x+2y-7=7-7
Then: Change the signs on both sides of the equation
3x-2y+7
Equaling: 3x-2y+7=0
9^3 is in exponential form
To do this you would have to do $2.00 times 1 1/4 to get the price of roast beef and $1.50 times 2 1/2.
1)To make it easier change the fractions to decimals.
(1.25)&(2.5)
2) Then do $2.00(1.25) to get
$2.50 for roast beef
3) Then do $1.50(2.50) to get
$3.75 for turkey
4)then add them together
5)3.75+2.50=$6.25
