All you have to do is plug in the coordinates into the problem to see if it is true or false:

5x - 2y + 1 > 0

5(-2) - 2(-1) + 1 > 0

-10 - (-2) + 1 > 0

-8 + 1 > 0

-7 > 0    ... So the answer would be FALSE

Answer:

False

Step-by-step explanation:

5x - 2y + 1 > 0

plug in  the given  ordered pair  x= -2 and y = -1:-

5(-2) - 2(-1) + 1

= -10 + 2 + 1

=  -7  which is less than 0 therefore the answer is False

Answer:

D -24/25

Step-by-step explanation:

sin(2x) = 2sin(x)cos(x)

cos(x) = ⅘

sin²(x) = 1 - cos²(x) = 1 - (⅘)²

sin²(x) = 9/25

sin(x) = -⅗

(Because 4th quadrant)

sin(2x) = 2(-⅗)(⅘)

= -24/25

1)Grace makes $12.23 selling each pepper pot soup bowl. If she sells 16 in one day, how much does she make in a day?
suter [353]

1.) First you have to multiply $12.23 by 16 which gives you $195.68

2.) The first step is to divide 2 4/8 by 2 because there's two people sharing the fruit. The answer is "each person get's 1.25"

What is the surface area of the triangular prism?
trasher [3.6K]

The surface area of the triangular prism is: B. 72 sq. ft

<h3>Surface Area of a Triangular Prism</h3>
  • The surface area of a triangular prism is given by the formula: SA = bh + (s1+s2+s3)H
  • Where, b is the base, h is the height, and s1+s2+s3 is the perimeter of the triangular base, H is the length of the prism.

Thus, given the triangular prism as shown in the diagram attached below, we have the following:

b = 4 ft

h = 3 ft

H = 5 ft

s1 + s2 + s3 = 3 + 4 + 5 = 12 ft

  • Plug in the values

Surface area = 4×3 + (12)5 = 12 + 60 = 72

Therefore, the surface area of the triangular prism is: B. 72 sq. ft

A leaky faucet wastes 3600 gallons of water per year how many quarts of water are wasted per month [1 gallon = 4 quarts]
Natasha2012 [34]

Answer:

1200 Quarts of Water

Step-by-step explanation:

Starting off with 3600 gallons of water, we know that this needs to be changed to quarts, which to do this you multiply it by 4.

3600 x 4 = 14400

This now shows how many quarts of water are wasted every year, but we need it in months. To do this, we divide by twelve because there are 12 months in a year.

14400 / 12 = 1200

This leads you with the answer of 1200 quarts of water being wasted every month.
