Answer:

(D) 1+0.06m

Step-by-step explanation:

Let's say that m=$120

(A)= $127.2

(B)= $127.2

(C)= $127.2

(D)= $8.2

As you can see after I substituted in 120 for (m) and solved, D is the only equation that did not represent her current balance.

Answer:

Choice C, 1 1/4

Step-by-step explanation:

There are two ways you can go about this problem.

1. Convert 0.65 into a fraction. This will give us 13/20 when simplified.

2. You can add this to 3/5 by getting a common denominator. In this case, 12/20.

3. Add 13/20 and 12/20 to get 25/20.

4. Take the 20 out of the numerator to get 1 5/20 (Hopefully that made sense, if not let me know). Reduce the 5/20 to 1/4.

5. This gives us an answer of 1 1/4.

The other way:

1. Convert 3/5 to a decimal. This gives us 0.6.

2. Add it to 0.65, giving us 1.25

3. Convert 1.25 into a fraction, which is 1 1/4

Hope this helped!

[tex]1\frac{1}{4}[/tex] is the required number of 3/5 more than 0.65

Fractions represent the parts of a whole or collection of objects.

We need to find the number which is three by five more than zero point six five.

1. Convert 3/5 to a decimal.

This gives us 0.6.

2. Add it to 0.65,

0.6+0.65

We get 1.25

3. Now we Convert 1.25 into a fraction, which is 5/4.

Now we can write 5/4 in the form of mixed fraction i.e is [tex]1\frac{1}{4}[/tex]

Hence  [tex]1\frac{1}{4}[/tex] is the number  is 3/5 more than 0.65.

Answer:

The domain of the function is (-6,6]

The range of the function is [-12.6)

Step-by-step explanation:

Domain and Range of Real Functions

The domain of a function is the set of all possible inputs for the function.

The Range is the set of values the function takes when x moves into the domain.

If the graph of a real function is given, we can find both by using the rules of the horizontal or vertical lines.

If an imaginary vertical line is moved along the x-axis, it can touch or not the graph of the function. All the values of x where the line and the graph cross each other belong to the domain of the function.

The vertical line crosses the function from x=-6 (not included since there is a hollow dot there) to x=6 (included since there is a solid dot).

Thus, the domain of the function is (-6,6]

Similarly, when an imaginary horizontal line is moved along the y-axis, it touches the function from y=-12 (included) to y=6 (not included).

The range of the function is [-12.6)

Answer:

because y and x are equivalent and equal 15

Answer: (D)One-half the difference of n and 3

Step-by-step explanation:

The correct verbal expression for the function f(n) = 1/2 (n-3) is →

One-half the difference of n and 3.

A mathematical expression when written using verbal statements is known as the verbal expression of that mathematical expression.

Given is the following mathematical expression -

f(n) = 1/2 (n-3)

The given expression is -

f(n) = 1/2 (n-3)

Now, Assume A = (n - 3) represents the the difference of n and 3.

1/2 (A) represents its one half.

Therefore, the correct verbal expression for the function f(n) = 1/2 (n-3) is → One-half the difference of n and 3.

Answer:

Step-by-step explanation:

11=-5x-2  add 2 to both sides

13=-5x  divide by -5

x= -13/5 or -2.6

The solution to the equation is x = -13/5.

To solve the equation 11 = -5x - 2, we need to isolate the variable x.

Now adding 2 to both sides:

11 + 2 = -5x - 2 + 2

This simplifies to:

13 = -5x

Next, we want to isolate the variable x, so we need to get rid of the coefficient -5.

Then divide both sides of the equation by -5:

13 / -5 = (-5x) / -5

This simplifies to:

-13/5 = x

Step-by-step explanation:

When you divide both sides of an inequality by a positive number, the inequality sign remains the same. When you divide both sides of an inequality by a negative number, you must reverse the inequality sign.

For example:

8 > 2 is a true inequality.

Let's divide both sides by 2:

4 > 1 is also a true inequality. The inequality sign remained > since we divided by a positive number.

Now let's start again with

8 > 2, and divide both sides by -2.

-4 > -1 is false. When the inequality sign remains the same after dividing both sides by a negative number, the inequality is no longer true. To keep the inequality true, we must change the inequality sign when dividing both sides by a negative number.

8 > 2

Divide both sides by -1.

-4 < -1 is true.

let me give you some advice. i think that you should try out GOOGLE perimeter calculator

Answer:

1) m=2/3

2) b=10

3) x-int:(-15, 0)

4) y-int: (0, 10)

Our equation is:

[tex]y=\frac{2}{3}x+10[/tex]

Step-by-step explanation:

To start, let’s find the equation of the line.

We can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

So, let’s substitute 2/3 for m and (-3, 8) for (x₁, y₁). This yields:

[tex]y-8=\frac{2}{3}(x-(-3))[/tex]

Simplify:

[tex]y-8=\frac{2}{3}(x+3)[/tex]

Distribute:

[tex]y-8=\frac{2}{3}x+2[/tex]

Add 8 to both sides:

[tex]y=\frac{2}{3}x+10[/tex]

This is in slope intercept form: y=mx+b.

Therefore, our m is 2/3 and our b is 10.

To find the x-intercept, we will substitute 0 for y and solve for x. Therefore:

[tex]0=\frac{2}{3}x+10[/tex]

Subtract 10 from both sides:

[tex]-10=\frac{2}{3}x[/tex]

Multiply both sides by 3/2. So:

[tex]x=-10(\frac{3}{2})=-30/2=-15[/tex]

Therefore, the x-intercept is (-15, 0).

To find the y-intercept, we will substitute 0 for x and solve for y. Therefore:

[tex]y=\frac{2}{3}(0)+10=10[/tex]

So, the y-intercept is (0, 10).

We will also graph it. See the attachment. To graph by hand, we can start at the y-intercept and go up two for every three to the right. Or, we can go down two for every three to the left. This should yield the following graph:

Answer:

Step-by-step explanation:

Answer:

r = 9

Step-by-step explanation:

Given that c varies directly as (r + 1) then the equation relating them is

c = k(r + 1) ← k is the constant of variation

To find k use the condition c = 8 when r = 3, then

8 = k(3 + 1) = 4k ( divide both sides by 4 )

2 = k

c = 2(r + 1) ← equation of variation

When c = 20, then

20 = 2(r + 1) ← divide both sides by 2

10 = r + 1 ( subtract 1 from both sides )

9 = r

c = k(r + 1)

8 = k(3 + 1)

8 = 4k

8/4 = k

2 = k

c=2(r + 1)

When c = 20, then

20 = 2(r + 1)

20 = 2r + 2

20 - 2 = 2r

18 = 2r

18/2 = r

9 = r

Therefore, the value of r is 9 when c is 20..

What is an expression?

Expression in math is defined as the collection of the number, variables and functions by using signs like addition, subtraction, multiplication, and division.

The absolute value equation is given as;

- |x - 4| + 2 = -2x + 7

Now, Solve the equation as;

- |x - 4| + 2 = -2x + 7

Subtract 2 both side,

- |x - 4| + 2 - 2 = -2x + 7 - 2

- |x - 4| = -2x + 5

Multiply by -1,

|x - 4| = 2x - 5

Since, the absolute value equation gives two equation as;

x - 4 = ± (2x - 5)

Take with positive sign;

x - 4 = 2x - 5

Add 4 both side,

x - 4 + 4 = 2x - 5 + 4

x = 2x - 1

2 x - x = 1

x = 1

And, Take with negative sign as;

x - 4 = - (2x - 5)

x - 4 = - 2x + 5

Add 4 both side,

x = -2x + 9

Add 2x both side,

x + 2x = 9

3x = 9

Divide by 3,

x = 3

Thus, The real solution of the absolute value equation are;

x = 1 and x = 3
