The range of a function is the set of all possible output values (y-values) that the function can produce for any input value (x-value).

y = -5 is a constant function, which means that the output value is always equal to -5 for any input value, the range of this function would be the set of real numbers that contain only the value -5.

The area of the partial circle with a radius of 8 cm = 150.72 [tex]cm^{2}[/tex], then the we can use  [tex]\pi =3.14[/tex] value.

The circle is missing 1/4, so the area of it is just 3/4 of the whole area of the circle.

Area of a circle is the region occupied by the circle in a two-dimensional plane.

It can be determined easily using a formula, A = [tex]\pi r^{2}[/tex] , (Pi r-squared) where r is the radius of the circle.

The unit of area is the square unit, such as [tex]m^{2}[/tex], [tex]cm^{2}[/tex], etc.

Area of Circle = [tex]\pi r^{2}[/tex] or [tex]\frac{\pi d^{2} }{4}[/tex], square units. where π = 22/7 or 3.14.

Area of a circle,

A = [tex]\pi r^{2}[/tex]      (Equation-1)

Where,

r = radius

Given that,

r = 8cm

We can substitute equation-1,

A = [tex]\pi 8^{2}[/tex] cm * cm

A = [tex]64\pi[/tex] [tex]cm^{2}[/tex]

So,

We can write,

Whole one quarter,

[tex]\frac{4}{4} -\frac{1}{4}[/tex] [tex]=\frac{3}{4}[/tex]

We can get,

= [tex]\frac{3}{4} *64\pi[/tex]

We can substitute [tex]\pi =3.14[/tex] value,

Then,

= 48 * 3.14

= 150.72 [tex]cm^{2}[/tex]

Therefore,

The area of the partial circle with a radius of 8 cm = 150.72 [tex]cm^{2}[/tex], then the we can use  [tex]\pi =3.14[/tex] value.

The amount that Pham will have to pay back is $8,602.80

The formula to calculate the compound interest is:

A = P(1 + r/n)^nt

Where A is the amount of the loan including interest, P is the principal or the initial amount borrowed, r is the interest rate, t is the number of years the loan is taken out for and n is the number of times the interest is compounded per year.

In this case, we know that:

P = $6,000

r = 6% (expressed as 0.06)

t = 72/12 = 6 (since the loan is for 72 months, or 6 years)

n = 1 (the interest is compounded annually)

So the formula becomes:

A = 6000(1 + 0.06)⁶

A = 6000(1.06)⁶

A = 6000 * 1.4338

A = $8,602.80

Therefore, Pham will have paid back $8,602.80, including interest, if he pays off the loan in 72 months.

The perimeter of the rectangle is 19.93 meter and the area of the rectangle is 22.22 sq. meter.

Here one side of the rectangle is 3( 3/10 ) and the other side is 6 (2/3 ) meter respectively.

Perimeter of the rectangle is 2 ( l + w ) and the Area of the rectangle is (l)*(w), where l is the length and w is the width of the rectangle.

Perimeter = 2(3 3/10 + 6 2/3) = 2(3.3 + 6.666667) = 2(9.96667) = 19.93334 meters

To find the area of a rectangle, we multiply the length by the width. The area of a rectangle with side lengths of 3 3/10 meters and 6 2/3 meters is:

Area = (3 3/10) * (6 2/3) = 3.3 * 6.666667 = 22.222222 square meters

The additive inverse of 11 /- 25 is -11 /+ 25. This means that the two numbers have opposite signs and the same absolute value.

The additive inverse of a number is the number that, when added to the original number, results in a sum of zero. In other words, the two numbers have opposite signs and the same absolute value. For example, the additive inverse of 11 /- 25 is -11 /+ 25. This is because when adding 11 /- 25 and -11 /+ 25 together, the negative and positive signs cancel each other out and the absolute values add up to zero. The same concept applies to all numbers, not just integers. For example, the additive inverse of 4.7 is -4.7. When 4.7 and -4.7 are added together, the sum is 0. As such, the additive inverse of any number can be calculated by changing the sign of the number and leaving the absolute value the same.

Answer:

1) The trick to making these fractions equivalent is to make sure they have the same denominator. to do this you need to know your multiplication facts. These are the multiples when you multiply two numbers together.

2) Since 24 is the largest denominator, you need the smallest denominator into 24ths, which you do by multiplying 8 x 3, giving you 24.

3) Whatever you do to the denominator, you do to the numerator, so multiply 5 x 3, which is 15.

4) New fraction for 5/8 becomes 15/24.

5) So 5/8 is equivalent. to 15/24.

Step-by-step explanation:

5/8 = x/24

5 x 3 = 15

8 x 3 24

Proof: Reduce 15/24 by dividing 3 into both numbers (15÷3) and (24÷3) = 5/8.

Answer:

We can start by using algebra to represent the given information in the problem in terms of variables. Let x be the cost of each candy bar. Then we can write the following equation:

3 + 7x = 31

This equation states that the total cost of the soft drink and the candy bars is $31, and the cost of the candy bars is 7 times the cost of each candy bar.

Now we can solve for x, the cost of each candy bar:

3 + 7x = 31

7x = 31 - 3

7x = 28

x = 28/7

x = 4

Each candy bar cost $4.

We can also check this by substituting this value back into the original equation to see if it is true:

3 + 7(4) = 31

3 + 28 = 31

31 = 31

This confirms that the cost of each candy bar is $4.

Answer:

Slope intercept form is y = -x+7

Standard form is x+y = 7

Both forms represent the same line, just written in different ways of course.

The graph is shown below.

=====================================================

Explanation:

Let's check the answer you got.

The equation -1x+y=1 is the same as -x+y = 1

Plug the coordinates of the first point into this equation

-x+y = 1

-3+4 = 1

1 = 1

The first point is on the line -x+y = 1

Repeat similar steps for the other point

-x+y = 1

-(-1)+8 = 1

1+8 = 1

9 = 1

The two sides don't match up. We need the same number on both sides to get a true equation. The false equation tells us that (-1,8) is not on the line -x+y = 1.

In short, this rules out -x+y = 1 being the answer.

The next section will show one way to find the answer.

--------------------------------

First we'll need the slope of the line through (3,4) and (-1,8)

[tex](x_1,y_1) = (3,4) \text{ and } (x_2,y_2) = (-1,8)\\\\m = \text{slope} = \frac{\text{rise}}{\text{run}} = \frac{\text{change in y}}{\text{change in x}}\\\\m = \frac{\text{y}_{2} - \text{y}_{1}}{\text{x}_{2} - \text{x}_{1}}\\\\m = \frac{8 - 4}{-1 - 3}\\\\m = \frac{4}{-4}\\\\m = -1\\\\[/tex]

Then I'll use the y = mx+b template to find b. For the (x,y), use either point given to you. I'll use (3,4).

So,

y = mx+b

4 = -1*3+b

4 = -3+b

4+3 = b

7 = b

b = 7

We found that m = -1 and b = 7.

We go from y = mx+b to y = -1x+7 aka y = -x+7 which is the answer in slope intercept form.

To convert to standard form Ax+By = C, add x to both sides. The goal is to get the variable terms to one side, and the constant isolated on its own side.

y = -x+7

y+x = -x+7+x

x+y = 7 is the answer in standard form

--------------------------------

Check:

Plug (x,y) = (3,4) into the equation to see if we get a true result.

x+y = 7

3+4 = 7

7 = 7

That works out. Now do the other pair of coordinates (-1,8).

x+y = 7

-1+8 = 7

7 = 7

That works as well. The answers are fully confirmed to be correct.

If you wanted, you can use the equation y = -x+7 as the way to check the answer. It's up to you which you prefer better if it's slope-intercept or standard form.

Yet another way to check the answer is to use a graphing tool like GeoGebra. It's something I use all the time. See the screenshot diagram below.

The rate of change of y with respect to x will be equal to 8 when there is a linear relationship between x and y.

The pace at which one quantity changes in relation to another quantity is known as the rate of change function. Simply said, the rate of change is calculated by dividing the amount of change in one item by the equal amount of change in another. The relationship defining how one quantity changes in relation to the change in another quantity is given by the rate of change formula.

The rate of change is given by the formula:

Here, the value of points are (-2.5,-30) and (-1,-18)

Now, substituting these values in the formula, we get

Rate of change=

= 8

Hence, the rate of change of the y with respect to x will be equal to 8 when there is a linear relationship between x and y.
