Answer:

{5, -3} {0, -1/3}

Step-by-step explanation:

For the first problem, they all have a GCF of 2, so you divide it all by 2 to get x^2-2x-15=0. Now, we need two factors of -15 that equal -2. Those are -5 and 3. Our new equation is x^2-5x+3x-15. To factor, the GCF of x^2 and 5x is x, so divide by x and you get x(x-5). The GCF of 3x and 15 is 3, so divide by 3 and you get 3(x-5). Now, put the numbers outside of the parenthesis into their own, and you get (x+3)(x-5). To get to 0, for the first one x has to be -3, and for the second, x has to be 5.

For the second, 12x^2 and 4x have a GCF of 4x. Since this we don't have a c value, we just divide and factor like this: 4x(3x+1). Since 4x is outside the parenthesis but we don't have any other terms outside, x=0 because 4(0) is 0. To cancel out 1, our x value inside has to be -1/3, because -1/3*3=-1.

Answer:

Step-by-step explanation:

A rational function contains a polynomial in both the numerator and the denominator. This answer fits that requirement.

Based on the information given, the area that will be left uncovered will be 450ft².

= 30 × 30 = 900ft²

The area viewed by the camera = 112.5ft²

Therefore, the number of cameras needed will be:

= 900/112.5 = 8

When he places the cameras in the corners of the store, he area covered will be:

= 4 × 112.5 = 450ft²

Therefore, the area left uncovered will be:

= 900 - 450

= 450 ft²

Answer:

C. 31 units

Step-by-step explanation:

Circumference of a circle is the distance around the circle and is given by C = pi•d

Your circle with a point and center given has a radius of 5 because from (2,1) to (7,1) is 5 units. Radius 5 means the diameter is 10.

C = pi•10

= 3.14•10

= 31.4 using 3.14 as an approximation for pi.

Circumference is approximately 31 units.

    7=a-5. What does a equal?

[tex]\dashrightarrow\large\textsf{\textbf{\underline{Answer and how to solve:-}}}[/tex]

When solving an equation, it's always a great idea to make sure all variables are on the left side of the equation and the numbers are on the right.

Since in our equation, we have numbers on both sides, we need to move all numbers to one side:-

7=a-5

This is the same as

a-5=7

Now, add 5 on both sides:-

a=12

So we conclude that a=12.

The equation of the line which is perpendicular to 3x - y = 10 is y = -(1/3) x + c. Then the correct option is B.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The line that is perpendicular to 3x - y = 10.

The equation can be written as

y = 3x - 10

Then the slope of the line will be

m₁ = 3

Let m₂ be the slope of the second line.

The product of the slope of the perpendicular lines is a negative one.

m₁m₂ = -1

 3m₂ = -1

   m₂ = -1/3

Then the equation of the perpendicular line will be

       y = - (1/3)x + c

     3y = -x + c

x + 3y = c

where c is the constant.

Thus, the correct option is B.

The standard equation of the circle in the graph is (x - 2)² + (y - 5)² = 16

From the graph, we have the following parameters:

The equation of the circle is then calculated using:

(x - a)² + (y - b)² = r²

So, we have:

(x - 2)² + (y - 5)² = 4²

Evaluate

(x - 2)² + (y - 5)² = 16

Hence, the standard equation of the circle in the graph is (x - 2)² + (y - 5)² = 16
