Answer:

3. (2, 1)

Step-by-step explanation:

The solutions are the points located inside the shaded region. The only point not located in that region is the point (2, 1). Therefore, (2, 1) is not a solution to the system of inequalities.

Answer:

r=28

Step-by-step explanation:

36/42 = 24/r (determine the defined range)

36/42 = 24/r , r ≠ 0 ( Reduce the fraction)

6/7 = 24/r (cross multiply)

6x = 168 ( divide both sides)

r=28 , r ≠ 0

Answer:

r = 28

Step-by-step explanation:

Cross multiply and solve for r:

[tex]\frac{36}{42}[/tex] = [tex]\frac{24}{r}[/tex]

36r = 1008

r = 28

So, r = 28

Answer:

1.9x+3.7

Step-by-step explanation:

Subtract 3.6x-1.7x

and 5.9-2.2    

The solution is 1.9x + 3.7

The value of the equation is given as A = 1.9x + 3.7

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

A = 3.6x + 5.9 - 2.2 - 1.7x   be equation (1)

On simplifying the equation , we get

On grouping the similar terms

The value of A = ( 3.6x - 1.7x ) + ( 5.9 - 2.2 )

The value of A = 1.9x + 3.7

Therefore , the value of A is 1.9x + 3.7

Hence , the equation is A = 1.9x + 3.7

Answer:

900°

Step-by-step explanation:

What is the sum of the measures of the interior angles of a 7-gon?

The formula to measure the interior angles of a polygon

= (n- 2) × 180 °

Where,

n = number of sides

We are given 7 - gon

This means it has 7 sides = Heptagon

Hence,

The measure of the interior angle is given as:

(7 - 2) × 180°

= 5 × 180°

= 900°

The sum of the interior angles of a 7-gon is 900°

Answer:

5/7 x 14/20= 1/2 or 0.5

Answer:

y= 3/2 x -2

Step-by-step explanation:

I guess you want to find the y=mx+b form

So you do +3x on both sides which will gave you: 2y= 3x-4

Then, you will divide by two on both sides to find the y value: 2y/2 = (3x-4)/ 2

So 3/2 is the fraction like the answer above and -4/2 = -2

Answer:

2 or C

Step-by-step explanation:

I'm taking this to mean

4 = 2(x - 1)^2

4 = 2(x^2 - 2x + 1)

4 = 2x^2 - 4x + 2

2x^2 - 4x - 2  =  0

x^2 - 2x - 1 = 0

What you get from here is sqrt(2) as one of the roots.

That is not nearly an answer.

4 = 4(x -1)

4 = 4x - 4

8 = 4x

x = 8/4

x  =  2

That makes C the answer.

Answer: 2100 square feet

Step-by-step explanation: 60 x 35=2100

Answer:

2100 ft squared!

Step-by-step explanation:

The formula to find the area of a rectangle is L * W = A

Where A is the total area, and L and W are the dimensions.

Since we know what the dimensions of the rectangles are, we can replace L and W to find out the area. This will look like this: 60 * 35 = A

Now we just have to multiply 60 and 35 to find A. This will simplify to 2100, which means the total are of the rectangle, or in this case, the soccer field, is 2100 ft squared!

Answer: 23 years

Step-by-step explanation:

From the question, we are informed that the length of an island is decreasing a rate of 16 inches per year. The number of years that it will take for the change in length of the island to be -364 inches would be gotten by dividing 364 by the rate of decrease every year which is 16 inches. Therefore, this would be:

= 364 / 16

= 22.75 years

= 23 years approximately
