Answer:
C, $4.47
Step-by-step explanation:
Firstly you would see that the cost of 5.2 pounds of grapes is $7.75, so you would divide to find the cost of 1 pound of grapes so 7.75/5.2= 1.49 (round to the nearest 100). Then, times 1.49 by 3. Then you get $4.47
Answer:
The slope of the line would be undefined
Step-by-step explanation:
First you take the y of the second point and subtract it from the y of the first point. -11 - 4. That leaves you with -15. Then you take the x of the second point and subtract it from the x of the first point. that leaves you with 0. Then you put y over x. You then have -1`5/0. That is undefined.

Step-by-step explanation:
(103,581) • (%110)
= (103,581) • (1.10)
= $113,939.1
Answer:
C, E
Step-by-step explanation:
Here, we want to change the equation of a circle from general form to standard form. This is done by making the leading coefficients 1, completing the squares, and then rewriting the equation in standard form.
The leading coefficients of the given equation are 2, so we first want to divide by 2. This gives ...
x² +y² -4x -6y +8 = 0
Subtracting 8 puts us in better position to complete the squares.
x² +y² -4x -6y = -8
Now, we can add the squares of half the coefficients of the linear terms.
(x² -4x +4) +(y² -6x +9) = -8 +13 . . . . . . matches C
And we can simplify this to the standard form equation:
(x -2)² +(y -3)² = 5 . . . . . matches E
Anything to the power of 0 is just 1
