How to solve -7+7s-3s-5-6-5s

→ -7+7s-3s-5-6-5s

The answer is -18-1s

Answer:

(-12, -20).

Step-by-step explanation:

A dilation of factor 4 moves (-3, 5) to (-3*4, 5*4) = the point (-12, 20).

A reflection  over  the x-axis is (x, y) ------> ( x, -y).

So ( -12, 20) goes to (-12, -20).

The factored form of a quadratic function reveals its root.

A quadratic function is a polynomial function with one or more variables in which the highest exponent of the variable is two.

We have,

Factor form of a quadratic function.

Factoring quadratics is a way of expressing the quadratic function:

ax2 + bx + c = 0

as a product of its factors as:

(x - k) (x - h),

where h, k are the roots of the quadratic function.

Answer:

The sequence does map shape I onto shape IV. So, the sequence of transformations proves the two shapes are similar.

Step-by-step explanation:

To check whether the sequence proves that shape I is similar to shape IV, check whether the given sequence of transformations maps shape I onto shape IV.

1. Dilate shape I by a scale factor of 2.

2. Then, reflect the dilated shape across the x-axis.

3. Finally, translate the reflected shape 1 unit left.

Answer:

This equation is in y=mx + b form. Just plug in the point to get N, which is also B.

Whatever is in f(x) is your x. So x = 9; This means...

4 = 2/3(9) + n

Solving for n gets you -2.

Now we plug in -3 and also substitute N now that we solved for it.

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

f(-3) = -4

If you need explanation I will give one

Explanation:

If the common difference is 0, then we're adding 0 to each term to get the next term. However, adding 0 doesn't change the number. So that's why we have the same thing written four times.

As another example, let's say the common difference was 1 instead of 0. That would mean the first four terms are -2, -1, 0, 1 since we add 1 to each term to get the next one (eg: -2+1 = -1).

Answer:

-2, -2, -2, -2.

Step-by-step explanation:

If the common difference (d) is 0 then all terms are the same as the first:-

AP = a, a + d, a + 2d, a + 3d

Here we have -2,  -2+0, -2 + 2(0), -2 + 3(0)

a) Number = x

Multiply it by 3 = 3*x = 3x

Now add 4 to it: 3x + 4

Equation:  

3x +4 = 22

b)

3x + 4 = 22

Subtract 4 from both sides

3x + 4 -4 = 22 - 4

        3x = 18

Divide both sides by 3

3x/3 = 18/3

x = 6

Answer:

Below in bold.

Step-by-step explanation:

The equation is

3x + 4 = 22

3x = 22 - 4 = 18

x = 18/3

Using mean and outlier concepts, it is found that:

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

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

Thus, the mean is:

[tex]M = \frac{80 + 92 + 91 + 75 + 89 + 84 + 0 + 85}{8} = 74.5[/tex]

Brandee's mean was of 74.5, which doesn't really represent her abilities, as in 7 of the 8 tests she got higher grades than this, but her mean is really affected by the outlier grade of 0%, for the test she missed.

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

[tex]M = \frac{80 + 92 + 91 + 75 + 89 + 84 + 90 + 85}{8} = 85.75[/tex]

Brandee's new mean will be of 85.75, which increases her final grade by 11.25 points, and is a more accurate representation of her abilities, as there is not an outlier grade.

Answer:

Step-by-step explanation:

(f-g)(x) = f(x)- g(x)

= (3x + 7) - (3x)

= 7

Therefore (f-g)(x) = 7

Answer:

(f - g)(x) = 7

Step-by-step explanation:

Here, we should subtract the two functions:

f(x) = 3x + 7  and g(x) = 3x

(f - g)(x) = 3x + 7 - 3x

            = 3x - 3x + 7

           = 7

Hence, (f - g)(x) = 7

Answer:

x = 2

Step-by-step explanation:

5-2x = -4x+9

5+(-2x+4x) = (-4x+4x)+9      [Add 4x to each side to get ride of 4x on the right]

5+2x = 9

(5-5)+2x = (9-5)     [subtract 5 from both sides to get rid of 5 on the left]

2x = 4

2x/2 = 4/2     [Divide each side by 2 to get x alone]

x=2

The solution to the equation 5 - 2x = -4x + 9 is x = 2.

Here, we have,

To solve the equation 5 - 2x = -4x + 9 step by step, we will combine like terms and isolate the variable x.

Here's how:

Start by simplifying both sides of the equation by combining like terms:

5 - 2x = -4x + 9

The left side has no like terms to combine, so we move to the right side:

-2x + 4x = 9 - 5

Simplifying further:

2x = 4

Now, we want to isolate the variable x.

To do that, we need to get rid of the coefficient 2 that is multiplied by x.

We can achieve this by dividing both sides of the equation by 2:

(2x)/2 = 4/2

Simplifying further:

x = 2

We have found the solution for the variable x.

Therefore, the solution to the equation 5 - 2x = -4x + 9 is x = 2.

2*x+5 the numbers of dimes

In cents,: 25*x+10*(2x+5)=365

25x+20x+50=365

45x=365-50
