Answer:

-15x - 12 + 9x^2

Step-by-step explanation:

(-7x - 5) - (-9x^2 + 8x + 7)

-7x - 5 + 9x^2 - 8x -7

-15x - 12 +9x^2

what is that 2 by the 9x

We will simplify the given expression to get:

9x^2 - 15x - 12

Here we have the expression:

(-7x - 5) - (-9x^2 + 8x + 7)

To simplify it, we just perform the difference between the polynomials:

-7x - 5 + 9x^2 - 8x - 7

Now we group terms with correspondent powers of x:

9x^2 + (-7x - 8x) + (-5 - 7)

Now we simplify this:

9x^2 - 15x - 12

This is the quadratic equation simplified.

so, Mikayla's savings = $ 160

Answer:

X = 3

Step-by-step explanation:

To solve for x, you can first divide both sides of the equation by 3. The reason you do this is because the left side is being multiplied by 3, so dividing would cancel it out

(3(3 + x) = 15 + x)/3   =  3 + x = 5 + 1/3x

Now, subtract 3 from both sides to isolate x on the left side

x = 2 + 1/3x

Lastly, subtract 1/3x from both sides

2/3x = 2

Now, divide both sides by 2/3 to get x = 3.

Answer:

b=-10

c=25

Step-by-step explanation:

if the only solution is 5 so

x^2+bx+c=(x-5)²=x²-10x+25

b=-10

c=25

For the given quadratic equation [tex]x^{2} +b x + c=0[/tex] value of 'b' = -10 and value of 'c' = 25.

" Quadratic equation are defined as the algebraic equation in which highest exponent of the variable is two. General form of quadratic equation  is [tex]ax^{2} + bx + c=0[/tex] where a≠0."

According to the question,

Given quadratic equation is,

[tex]x^{2} +b x + c=0[/tex]             ______(1)

Solution of the given quadratic equation x = 5.

From this we have,

[tex]x-5=0\\\\(x-5)^{2} =0[/tex]                      _____(2)

Equate equation (1) and (2)  to get the value of 'b' and 'c' ,

[tex]x^{2} +b x + c=(x-5)^{2}[/tex]

⇒[tex]x^{2} +b x + c= x^{2} -10 x + 25[/tex]

Compare Left hand side and right hand side we get,

b = -10

c = 25

Hence, for quadratic equation [tex]x^{2} +b x + c=0[/tex] value of 'b' = -10 and value of 'c' = 25.

Answer:

Julie has $11.51 left.

Step-by-step explanation:

We know that Julie has $20.  She spent $1.99 on package of trading cards and $6.50 for lunch.  When added this is equal to $8.49.

Now we have to figure out how much she has left by subtracting $20 from $8.49 and we get $11.51.  Therefore, $11.51 is our answer.

Given:

The figures of triangles and their mid segments.

To find:

The values of n.

Solution:

Mid-segment theorem: According to this theorem, mid segment of the triangle is a line segment that bisect the two sides of the triangle and parallel to third side, The measure of mid-segment is half of the parallel side.

9.

It is given that:

Length of mid-segment = 54

Length of parallel side = 3n

Using mid-segment theorem, we get

[tex]54=\dfrac{1}{2}(3n)[/tex]

[tex]2\times 54=3n[/tex]

[tex]108=3n[/tex]

Divide both side by 3.

[tex]\dfrac{108}{3}=n[/tex]

[tex]36=n[/tex]

Therefore, the value of n is equal to 36.

10.

It is given that:

Length of mid-segment = 4n+5

Length of parallel side = 74

Using mid-segment theorem, we get

[tex]4n+5=\dfrac{1}{2}(74)[/tex]

[tex]4n+5=37[/tex]

[tex]4n=37-5[/tex]

[tex]4n=32[/tex]

Divide both side by 4.

[tex]n=\dfrac{32}{4}[/tex]

[tex]n=8[/tex]

Therefore, the value of n is equal to 8.

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

Explanation:

Use the graph to see that the left and right endpoints of the original segment are (2,4) and (6,6) in that order.

Then for each point, we multiply each coordinate by the scale factor 2. This will move the points to the proper location such that the segment is now twice as long as compared to the original.

The left endpoint (2,4) moves to (4,8) after we double the coordinates.

The right endpoint (6,6) moves to (12,12) after we double the coordinates.

The final segment has the left and right endpoints of (4,8) and (12,12) in that order.

Side note: The original and final segments are parallel to one another. This is because both segments share the same slope.

Answer:

Option (4)

Step-by-step explanation:

We Fix it Computer Repair charges for it's services as per equation given as,

C = 30h + 90

Here, C = Total cost

h = Number of hours worked

This equation is in the form of a linear equation,

y = mx + b

Here, m = slope of the equation

And slope of the equation defines the unit rate

Therefore, charges for each hour of the first company = $30

Table given in the question represents the charges of another company John's Compute Repair.

There is a common difference in each successive term of the Total Cost of the table,

Common difference = 100 - 55 = 45

Therefore, this table represents a linear function.

Slope of the linear function passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the expression,

Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of the function represented by the table = [tex]\frac{100-55}{2-1}[/tex]

                                                                              = 45

Therefore, per hour charges by the second company = $45

Difference in the charges = $45 - $30

                                           = $15

John's Computer Repair charges more by $15.

Answer:

r ≈ 7.18%

Step-by-step explanation:

a = p(1 + r)^n

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

a = 10000 * 2 = 20000

p = 10000

n = 2035 - 2025 = 10

Plug in the knowns

20000 = 10000(1 + r)^(10)

Divide both sides by 10000

2 = (1 + r)^(10)

Take the log of both sides

log2 = 10 * log(1 + r)

Divide bot sides by 10

(log2)/10 = log(1 + r)

use calculator

0.030102999566398 = log(1 + r)

antilog both sides

10^0.030102999566398 = 1 + r

1.0717734625 = 1 + r

Subtract 1 from both sides

0.0717734625 = r

r ≈ 7.18%

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

Alternate method

2 = (1 + r)^(10)

Take 10th root of both sides

1.0717734625 = 1 + r

Subtract 1 from both sides

0.0717734625 = r

r = 7.18%
