For the first rectangle:
- Find the distance between (-4, 3) & (-2, 6) and (2, -1) & (-4, 3)
- Multiply the distances to get the area of the rectangle.
For the second rectangle:
- Find the distance between (-4, 4) & (-1, -5) and (2, -4) & (-4, 4)
- Multiply the distances to get the area of the rectangle.
Compare areas to see which one is larger.
This is the anwser to your equation

x< 15 where x is the average that each person contributes.
This gives 3x <45, limiting the gift basket's total cost to < $45. (Actually ≤ 14.99 per person, so max cost is $44.97.
19. simple algebra
a <= -4 + 7
a <= 3
20.
since u divide and the co efficient is negative u flip the sign
-3m<15
m>-5
A linear regression equation is a line so it has a form of y = mx + b, which is an equation of a line. You will also see it as Y = a + bX. In the form of Y= a +bX the b is the slope.
There are different methods to fitting a line and the most common method is the method of least-squares.
Answer:
296.97
Step-by-step explanation:
Remark
The first thing you have to realize is that you take the discount before you add the sales tax.
Discount
If she receives a 15% discount, she still pays 85% of the full price.
85/100 * 325 = 276.25
Sales Tax
A sales tax is only added on after a goods or service has been determined and agreed upon by the buyer and seller.
The sales tax can be calculated quickly by adding the decimal equivalent onto 1 and multiplying that by the discounted amount.
1 + 7.5% = 1 + 7.5/100 = 1 + 0.075 = 1.075 deriving the discount amount
Cost
Cost = discounted price * 1.075 Substitute in Formula
Cost = 276.25 * 1.075 Simplify
Cost = 296.97 Answer
