Step-by-step explanation:

I just did it on Kahn Academy, and this was correct.

The range of the function is {-1, 3, 15}.

The set of a function's potential output values is known as its range.

Given that, the domain of the function is {0,2,-6}.

The range is the set of the output of the functions for the given domain values.

The value of y for x = 0 is:

y = -2(0) + 3

y = 3

Similarly, the values of y for x = 2 and x = -6 are:

y = -2(2) + 3

y = -1, and

y = -2(-6) + 3

y = 15

Hence, the range of the function is {-1, 3, 15}.

Answer:

The scale factor of the dilation is [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and this ratio is called the scale factor

Let

z------> the scale factor

so

[tex]z=\frac{K'J'}{KJ}=\frac{K'H'}{KH}=\frac{J'H'}{JH}[/tex]

substitute the values

[tex]z=\frac{K'J'}{KJ}[/tex] ----->  [tex]z=\frac{1}{4}[/tex]

The scale factor is less than 1

therefore

The dilation is a reduction

The correct option is the x-coordinate of the vertex representing the length.

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.

It is written in the form of ax²+bx+c.

As it is given that the perimeter of the rectangular fencing is 1600 m.

Now, since the shape of the fence is rectangular, therefore, the x-coordinate of the vertex represents the length that results in the largest possible area, while the y-coordinate is the width of the rectangular fencing.

Hence, the correct option is the x-coordinate of the vertex representing the length.

Final answer:

To find the dimensions of the barn's wall, we set up the equation w x (2w + 4) = 96 and solved for w to find the width is 8 feet. Then, we used the width to find the length, which is 20 feet.

Explanation:

To solve the problem of finding the dimensions of the rectangular wall of the barn, we need to set up and solve an algebraic equation. Let's call the width of the wall w feet. According to the problem, the length is 4 feet longer than twice the width, so we can express the length as 2w + 4 feet.

The area of the rectangle is given by multiplying the length by the width. We know the area is 96 square feet, so our equation to solve is w × (2w + 4) = 96.

Expanding this equation gives us 2w^2 + 4w - 96 = 0. This is a quadratic equation that we can solve by factoring, completing the square, or using the quadratic formula.

Factoring the quadratic equation, we look for factors of -96 that add up to 4. These factors are 12 and -8. So, we can write our equation as (2w + 12)(w - 8) = 0.

Setting each factor equal to zero gives us two possible solutions for w: w = -6 or w = 8. Since width cannot be negative, we discard w = -6 and keep w = 8 feet. The length is then 2(8) + 4 = 16 + 4 = 20 feet.

Therefore, the width of the barn's wall is 8 feet, and the length is 20 feet.

Answer:

To find the image of B, first find the scale factor for the dilation. The scale factor should be greater than 1 because the image of A is farther from the origin than A. Divide the coordinates of the image of A by the coordinates of A: –6/–4 = 3/2 and 9/6 = 3/2, so the scale factor is 3/2. Now, apply the dilation to B by multiplying the coordinates by 3/2 to get ((3/2)(1), (3/2)(4)), or (3/2, 6).

Final answer:

By adding 22 to -7, we find that the number 22 spaces to the right of -7 on the number line is 15.

Explanation:

The question asks for the number that is 22 spaces to the right of negative 7 on a number line. To find this, you can simply add 22 to negative 7. Here's the calculation: -7 + 22 = 15. Therefore, the number that is 22 spaces to the right of negative 7 is 15. To determine the number that is 22 spaces to the right of -7 on the number line, we need to add 22 to -7. Moving 22 spaces to the right indicates an increase in value by 22. Therefore, when we add 22 to -7, we get the final answer of 15. This calculation reflects the concept that moving to the right on the number line corresponds to increasing the numerical value, while moving to the left corresponds to decreasing it. In this case, starting from -7 and moving 22 spaces to the right results in a value of 15. Hence, 15 is the number that is 22 spaces to the right of -7.

Answer:

Q(2, −1), S(−6, 5)

Step-by-step explanation:

The original ordered pairs were  (2, 1) and (−6, −5). When you reflect across the x-axis the x-coordinates of the two ordered pairs are the same, and the y coordinate is the opposite in sign (positive and negative).

so since the original ordered pairs were  (2, 1) and (−6, −5), the reflected ordered pairs would be  Q(2, −1), S(−6, 5) because the y-coordinates are different and the x-coordinates are the same.

Hope this helped fellow FLVS student!!

The coordinates are Q(2, −1) and S(−6, 5)

A reflection point occurs when a figure is constructed around a single point, known as the point of reflection or centre of the figure. For every point in the figure, another point is found directly opposite to it on the other side. Under the point of reflection, the figure does not change its size and shape.

Given that, On a coordinate grid, point P is at (2, 1) and point R is at (−6, −5). Points Q and S are a reflection of both points across the x-axis.

We know that, when you reflect across the x-axis, the x-coordinates of the two ordered pairs are the same, and the y coordinate is the opposite in sign (positive and negative).

So, since the original ordered pairs were  (2, 1) and (−6, −5), the reflected ordered pairs would be  Q(2, −1), S(−6, 5) because the y-coordinates are different and the x-coordinates are the same.

Hence, The coordinates are Q(2, −1) and S(−6, 5)

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. LHS = RHS is a common mathematical formula.

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:

2x-3y = -12...........(1)

4x+ y= -10..............(2)

Now, multiply Equation (1) by 2 we get

4x - 6y = -24

4x + y = -10
