Answer:

(x - 5)² = 17

Step-by-step explanation:

Given

0 = - x² + 10x - 8 ( multiply through by - 1 to clear the leading negative )

x² - 10x + 8 = 0 ( subtract 8 from both sides )

x² - 10x = - 8

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 5)x + 25 = - 8 + 25

(x - 5)² = 17

Answer:

The two bowling alleys cost the same when there are 10 people in the group.

Step-by-step explanation:

Bustlin' Bowling first:

$35 base price and then $2 for each person. You can model that with b = 35 + 2x where b is the price and x is the guest number.

Grand Entertainment next:

$20 base price and then $3.50 for each person. You can model that with g = 20 + 3.5x where g is the price and x is the guest number.

So the question asks for the number of people (or what's x) that makes the cost of both bowling places equal.

In variables, it's asking when b = g, what is x?

Starting with b = g, we can replace those with the actual equations. If b = 35 + 2x and g = 20 + 3.5x, then b = g is the same as 35 + 2x = 20 + 3.5x.

I think you know how to solve that (because the trickiest part is usually translating the words into a solvable equation) but in case you don't, here's how:

35 + 2x = 20 + 3.5x

Subtract 2x from both sides.

35 = 20 + 3.5x - 2x

35 = 20 + 1.5x

Subtract 20 from both sides.

35 - 20 = 1.5x

15 = 1.5x

Divide both sides by 1.5.

15/1.5 = 1.5x/1.5

10 = x

Sooo, the answer is 10 people.

Answer:

it would be 6 and 6 since it states equal distance and it also says a few forward and a few backward. It makes it sound like this was an equal amount each way

Step-by-step explanation:

Answer:

6 steps forward and 6 steps backward

Step-by-step explanation:

If the bear ended up back at its starting position, this means that the distances forward and backward have to be the same.

Since 6 = 6, this answer is correct.

The bear would have to take the same amount of steps forward and backwards.

Answer:

I'm late but the answer to the question on the left is 21 and the answer to the question on the right is 3.

Step-by-step explanation:

Remember that you have to complete the equations in order of PEMDAS.

19-3×4÷(-6)

For this equation, you would do 3×4 first (which equals 12) then divide that by -6 (Which equals - 2) and finally you would subtract that from 19. 19 - (-2)= 21

6(-8) / -12 - 1

For this equation you would do 6(-8) first (which equals -48) then divide that by -12 (which equals 4) and finally subtract 1 from that 4. 4-1=3

Answer:

1. 35

2. 145

3. 55

4. 90

5. 145

Step-by-step explanation:

1. 35: angle 1 and 2 are a linear pair (meaning it is in one line and adds to 180). Since we know angle 2 is 145, ∠1 = 180 - 145

∠1 = 35

2. 145: ∠7 = ∠2 because they are alternate angles and alternate angles are equal

3. 55: ∠7 = ∠5 + ∠4 because vertically opposite angles are equal. We know that ∠5 = 90, hence ∠4 would equal 145 - 90 = 55

4. ∠5 = 90. It is given

5. 145: ∠9 = ∠2 because they are vertically opposite

The value of the given exponent is [tex]\frac{5}{2}[/tex]

Given:

The exponent = [tex](\frac{4}{25})^{\frac{-1}{2}}[/tex]

To find:

The value of a given exponent

Solution:

[tex](\frac{4}{25})^{\frac{-1}{2}} = ?[/tex]

Using the identity of an exponent : [tex](\frac{m}{n})^{x} = \frac{m^{x}}{n^{x}}[/tex]

[tex](\frac{4}{25})^{\frac{-1}{2}} = \frac{(4)^{(\frac{-1}{2})}}{(25)^{(\frac{-1}{2})}}\\[/tex]

Using the identity of an exponent : [tex]a^{-x} = \frac{1}{a^x}[/tex]

[tex]=\frac{(25)^{(\frac{1}{2})}}{(4)^{(\frac{1}{2})}}\\=\frac{(25)^{(\frac{1}{2})}}{(4)^{(\frac{1}{2})}}\\=\frac{((5)^2)^{(\frac{1}{2})}}{((2)^2)^{(\frac{1}{2})}}\\[/tex]

Using the identity of an exponent: [tex](a^{n})^m=a^{m\times n}[/tex]

[tex]=\frac{5^{(2\times \frac{1}{2})}}{2^{(2\times \frac{1}{2})}}\\=\frac{5^1}{2^1}\\=\frac{5}{2}[/tex]

The value of the given exponent is [tex]\frac{5}{2}[/tex].

Answer:

RS = 14

Step-by-step explanation:

Perimeter = 26 + 26 + PT + RS

We know that PT and RS are equal to each other so I changed the equation to 26 + 26 + x + x = 10 + 5x and then I got x by itself and the integer on one side 42 = 3x, so 14 = x

The value of RS will be 14 for the given parallelogram.

A basic quadrilateral with two sets of parallel sides is known as a parallelogram.

A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size.

There are 4 types of parallelograms, including 3 special types. The four types are parallelograms, squares, rectangles, and rhombuses.

Given the parallelogram where TS ║ PR and both are equal

Line TP ║ SR so it means TP = SR

Let's say

TP = SR = x

Now,

The perimeter of a parallelogram is 10 more than 5(RS)

So,

PT + TS + SR + RP = 5(RS) + 10

Now since TP = RS = x

So,

x + TS + x + RP = 5x + 10

5x - 2x = TS + RP - 10

x =  (TS + RP - 10)/3

Now,

TS = RP = 26

So,

x = (26 + 26 - 10 )/3

x = 42/3

x = 14

Hence "The value of RS will be 14 for the given parallelogram".

4

3125

is already in the simplest form. It can be written as 0.00128 in decimal form (rounded to 6 decimal places).

Steps to simplifying fractions

Find the GCD (or HCF) of numerator and denominator

GCD of 4 and 3125 is 1

Divide both the numerator and denominator by the GCD

4 ÷ 1

3125 ÷ 1

Reduced fraction:  

4

3125

Therefore, 4/3125 simplified to lowest terms is 4/3125.

-143

Step-by-step explanation:

We have to substitute 4 into x.

g(4) = -3(4)^2 + 2(4) - 7

g(4) = -12^2 + 8 - 7

g(4) = -12^2 + 1

-144 + 1

-143

-47

Step-by-step explanation:

= -3(4)^2 +2(4) -7

= (-3×16) +8 - 7

= -48+8-7

= -40-7

= -47
