20 1/4 = 20.25
20.25/9 = 2.25
2.25 =
Each cake weighs 2.25 pounds.
Answer:
1. Slope: -3/4
2. Point-slope: y+4=-3/4(x+4)
3. Slope-intercept: y=-3/4x-7
4. Standard form: 3x+4y=-28
Step-by-step explanation:
1. To find the slope, use the slope formula, which is: y2-y1/x2-x1.
Plug the y-coordinates into the top part of the equation and the x-coordinates into the bottom part.
2--4/-4-4
2+4/-8 = 6/-8, or 3/-4
2. Use the slope and one of the x and y coordinates to put the equation into point-slope form. Recall that point-slope form is: y-y1=m(x-x1). Let's use the coordinates (4,-4).
y+4=-3/4(x+4)
3. To put the point-slope equation into slope-intercept form (y=mx+b), you need to distribute -3/4 to x+4 and subtract 4 from both sides.
When you distribute, the equation becomes:
y+4=-3/4x-3
Finally, when you subtract 4, the equation becomes:
y=-3/4x-7
4. Standard form is written as x+y= #.
To convert y=mx+b to standard form, first subtract -3/4x from both sides.
-3/4x + y = -7
Multiply everything by 4
3x + 4y = -28

Answer:
$719.95
Step-by-step explanation:
To find the purchase total, multiply the price by the percent paid and add the percent of tax.
The store offers a 20% discount. This means you pay 80% of the price. So the discounted price is 0.80(849) = 679.2.
Find the tax to be paid by multiplying 0.06(679.2) = 40.752.
Add the tax for the final total.
679.2 + 40.752 = 719.95
