Cost of the magazine and a pizza that was bought by Anja = $9.75
Let us assume the cost of the magazine bought by Anja = x dollars
Then
Cost of the pizza bought by Anja is =2x dollars
Then
x + 2x = 9.75
3x = 9.75
x = 9.75/3
= 3.25 dollars
So
The cost of the pizza bought by Anja = 2x
= 2 * 3.25 dollars
= 6.50 dollars
From the above deduction we can easily conclude that the cost of the pizza bought by Anja is $6.50.

Answer:
y=x+600
Step-by-step explanation:
Hey There!
Slope intercept form is y=mx+b
where m = slope and b = y intercept
slope is change in y over change in x
as y goes up 200 x goes up 200 so the slope is 200/200 or just 1
The y intercept is at (0,600) so the y intercept is 600 now we just put everything together and get that the equation is
y=x+600
The answer is <span>A. 12 and 8

x - y = 4
x * y = 96
_____
x = y + 4
x * y = 96
______
(y + 4) * y = 96
y² + 4y = 96
y² + 4y - 96 = 0
y² + 12y - 8y - 96 = 0
(y² + 12y) - (8y + 96) = 0
y(y + 12) - 8(y + 12) = 0
(y + 12)(y - 8) = 0
y + 12 = 0 or y - 8 = 0
y = -12 or y = 8
Since, the numbers are positive, then the only solution for y is 8.
x - y = 4
y = 8
x - 8 = 4
x = 8 + 4
x = 12
