Answer:

m= -1/26

Step-by-step explanation:

plug into the formula and solve

Answer:

2500 children and 2500 adults

The number of children is 2500 and the number of adults that attended the game is also 2500.

Let us consider that, number of children be x and number of adults be y that attend game.

Since, total 5000 people attend the game.

               [tex]x+y=5000\\\\x=5000-y..........(1)[/tex]

It costs $3 for children and $7 for adults and the total takings at the door was $25000

              [tex]3x+7y=25000 .............(2)[/tex]

Substitute value of x from equation 1 into equation 2.

           [tex]3(5000-y)+7y=25000\\\\15000-3y+7y=25000\\\\4y=10000\\\\y=10000/4=2500[/tex]

So that, [tex]x=5000-2500=2500[/tex]

Thus, the number of children is 2500 and the number of adults that attended the game is also 2500.

Answer:

y = - 1/2x + 5

Step-by-step explanation:

the slope is -1/2 because the line is declining two units to the right for every one unit down. and the "b" is 5 because the line hits the y-axis at +5

Answer:

No

Step-by-step explanation:

We can check with the Pythagorean Theorem.

a^2 + b^2 = c^2

  a and b are always the smaller sides, the legs

  c is the longer side, the hypotenuse

3^2 + 3^2 >  6^2

9 + 9 > 36

18 < 36

18 is not greater than 36, therefore this triangle can not have the side lengths 3, 3, and 6.

Answer: 149.12

Step-by-step explanation:

to find out the extended warranty we do,

466*(32/100)=149.12

The extended warranty cost is $149.12.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, a set of floor speakers costs $466.

If the extended warranty on the speakers costs 32% of the price of the speakers.

Now, extended price =32% of 466

32/100 ×466

= 0.32×466

= $149.12

Therefore, the extended warranty cost is $149.12.

Answer:

C. x-2

Step-by-step explanation:

x² + 7x - 18 = 0

the factor must be p and q from the form.of

(x+p)(x+q) = 0

then find the value of p and q by this rules

p + q = 7

p x q = -18

p = 9

q = -2

(x + 9)(x + (-2)) = 0

(x+9)(x-2) = 0

Answer:

c.) [tex](x-2)[/tex]

Step-by-step explanation:

The given expression is written in the form [tex]ac^2+bx+c[/tex]. To factor, find two numbers whose sum is b and whose product is c:

_×_=-18

_+_=7

Use -2 and 7:

-2×9=-18

-2+9=7

Substitute the two numbers for b:

[tex]x^2-2x+9x-18[/tex]

[tex](x^2-2x)+(9x-18)[/tex]

Factor out common terms. The common term in the first parentheses is x and the common term in the second is 9:

[tex]x(\frac{x^2-2x}{x} )+9(\frac{9x-18}{9})\\\\x(x-2)+9(x-2)[/tex]

Cancel out one of the parentheses since they have the same terms and plug the factored numbers in:

[tex](x-2)(x+9)[/tex]

:Done

Check Your Work:

To see if the given factored form is true, simplify it using FOIL:

First, Outside, Inside, Last

[tex](x-2)(x+9)[/tex]

Multiply the first terms:

[tex]x*x=x^2[/tex]

Multiply the terms on the outside:

[tex]x*9=9x\\\\x^2+9x[/tex]

Multiply the inside terms:

[tex]-2*x=-2x\\\\x^2+9x-2x[/tex]

Multiply the last terms:

[tex]-2*9=-18\\\\x^2+9x-2x-18[/tex]

Combine like terms:

[tex]x^2+(9x-2x)-18\\\\x^2+7x-18[/tex]

Therefore, the factored form is true.

x/x^2-9 + 1/x-3 = 1/4x-12

x/(x+3)(x-3)+1/(x-3)=1/4(x-3)

LCD: 4(x+3)(x-3)

4x+4(x+3)=(x+3)

4x+4x+12=x+3

Answer: 5 cars

Step-by-step explanation:

Breakeven point = Fixed Cost/ Contribution margin

Fixed cost is $30 which is the flea market booth charge

Contribution margin is sales price less variable cost.

The Variable Cost is the amount he is charged by the distributor of $14.

Contribution Margin = 20 - 14

= $6

Breakeven point = 30/6

= 5 cars

Answer:

Option A

Step-by-step explanation:

[tex]R = (\frac{V_f-Vi}{V_i} )100[/tex]

where,

[tex]V_f[/tex] is the final value

[tex]V_i[/tex] if the initial value

R is the investors rate of return

so,

[tex]R = (\frac{V_f-Vi}{V_i} )100\\\\R=(\frac{1500-1700}{1700})100 \\\\R=(\frac{-200}{1700})100 \\\\R=-11.8\\[/tex]

so the investors rate of return is -11.8%

-10<0

-4<-3

Step-by-step explanation:

if you are talking about what is greater than this is the answer

Answer: -10<0 -4<-3

Step-by-step explanation:-10 is less than 0 because negative(-)means that number less than 0. -4 is less than -3 because even though it’s a higher number it’s negative.

Given:

First term of an arithmetic sequence = 5

Second term = 3

To find:

The explicit formula for the given arithmetic sequence.

Solution:

We have,

First term: [tex]a_1=5[/tex]

Second term: [tex]a_2=3[/tex]

Common difference is

[tex]d=a_2-a_1[/tex]

[tex]d=3-5[/tex]

[tex]d=-2[/tex]

Now, the explicit formula for an arithmetic sequence is

[tex]a_n=a+(n-1)d[/tex]

where, a is first term and d is common difference.

Putting a=5 and d=-2, we get

[tex]a_n=5+(n-1)(-2)[/tex]

It can also be written as

[tex]a_n=5-2n+2[/tex]

[tex]a_n=7-2n[/tex]

Here, n is an integer greater than or equal to 1.

Domain is the set of input values.

Therefore, the explicit equation is [tex]a_n=5+(n-1)(-2)[/tex] or [tex]a_n=7-2n[/tex] and domain is all interest greater than or equal to 1.
