Which of the expressions are equivalent to the one below? Check all that apply. 13. (11 + 5)​

Answer:

Gym A

Step-by-step explanation:

A linear relationship is a relationship of the form y = mx + b, where y and x are the linear variables, m is the rate of change and b is the value of y when x = 0.

Gym A:

Let x represent the month and y represent the total cost for the gym. From the table, we can represent the values in the form (x, y) as (1,70), (2, 90) and (3, 110). We can find the relationship between x and y using the formula:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\Let \ us\ use\ the\ points\ (1,70)\ and\ (3,110),hence:\\\\y-70=\frac{110-70}{3-1}(x-1)\\\\y-70=20(x-1)\\\\y=20x-20+70 \\\\y=20x+50\\\\For\ 10\ months(i.e.\ x=10):\\\\y=20x+50\\\\y=20(10)+50\\\\y=\$250[/tex]

Gym B:

We can represent the values from the table as (1,55), (2, 80) and (3, 105). We can find the relationship between x and y using the formula:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\Let \ us\ use\ the\ points\ (1,55)\ and\ (3,105),hence:\\\\y-55=\frac{105-55}{3-1}(x-1)\\\\y-55=25(x-1)\\\\y=25x-25+55 \\\\y=25x+30\\\\For\ 10\ months(i.e.\ x=10):\\\\y=25x+30\\\\y=25(10)+30\\\\y=\$28 0[/tex]

Hence gym A would cost less ($250 < $280)

The value of x is 3.

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.

Given:

[tex]9^{-1/2} = 27^{1/4}[/tex]÷[tex]3^{x +1}[/tex]

[tex][3^{2}]^{{-1/2}} = [(3)^{4}]^{1/4}[/tex] ÷[tex]3^{x +1}[/tex]

[tex]3^{-1}[/tex] = 3 ÷[tex]3^{x +1}[/tex]

[tex]3^{-1}[/tex]= [tex]\frac{3}{3^{x+1}}[/tex]

[tex]3^{-1}= 3^{1-x+1}[/tex]

[tex]3^{-1}= 3^{2-x}[/tex]

On comparing we get,

-1=2-x

x= 3

Hence, the value of x is 3.

Answer:

The graph below shows that y = x+4 has one solution the rest are all parallel.

Step-by-step explanation:

Answer:

y = x + 4

Intersects at (0,4).

Step-by-step explanation:

y = 2x -4: No solution(parallel)

y = 2(x+2): Infinite many solutions(same line)

y = 2(x-4): No solution(Also parallel)

y = x + 4: One Solution(Intersects at (0,4)).

Answer:

The complete table will be:

Term #                Value of aₙ

1                            15

5                           27

10                          42

20                         72

Step-by-step explanation:

Given the sequence expression

aₙ = 15 + 3(n-1)

Substituting n = 1 for the first term

aₙ = 15 + 3(n-1)

a₁ = 15 + 3(1-1)

a₁ = 15 + 3(0)

a₁ = 15 + 0

a₁ = 15

Substituting n = 5 for the 5th term

aₙ = 15 + 3(n-1)

a₅ = 15 + 3(5-1)

a₅ = 15 + 3(4)

a₅ = 15 + 12

a₅ = 27

Substituting n = 10 for the 10th term

aₙ = 15 + 3(n-1)

a₁₀ = 15 + 3(10-1)

a₁₀ = 15 + 3(9)

a₁₀ = 15 + 27

a₁₀ = 42

Substituting n = 20 for the 20th term

aₙ = 15 + 3(n-1)

a₂₀ = 15 + 3(20-1)

a₂₀ = 15 + 3(19)

a₂₀ = 15 + 57

a₂₀ = 72

Therefore, the complete table will be:

Term #                Value of aₙ

1                            15

5                           27

10                          42

20                         72

Answer:

10 tickets = $5

25 tickets = $12.50

50 tickets = $25

100 tickets = $50

Step-by-step explanation:

If 1 ticket equals 0.50 in order to find the price for 10 all you do is do 10 x 0.50. The same for all the others. Just take the amount of tickets and multiply them by 0.50. :)

Answer:

D. 797,481

Step-by-step explanation:

So, with the number 653,841, the number that is in the hundreds place is 8, meaning that the number is 800. So now, since you have to find 1/10 of the value, you have to divid it by 10, giving you 80. Now, looking at the answers, you have to find the number with 8 in the tens place, which is D.

Answer:

y = -2/3x - 1

Step-by-step explanation:

Answer:

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

Step-by-step explanation:

Equation of line in point slope form is given as

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

Here

m=-2/3 and [tex](x_1, y_1)=(-1, 0)[/tex]

Equation of the line passing through the point (-1, 0) with slope -2/3 is

[tex]y-0=-\frac{2}{3} (x-(-1))[/tex]

[tex]y =-\frac{2}{3} (x+1)[/tex]

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

The worth of the car in 2 years is £1767.2

The given parameters are:

Value, a = £20000

Depreciation rate, r = 6%

The value of the car in t years is represented as:

f(t) = a *(1 - r)^t

This gives

f(t) = 2000 * (1 - 6%)^t

In 2 years, t = 2

So, we have:

f(2) = 2000 * (1 - 6%)^2

Evaluate

f(2) = 1767.2

Hence, the worth of the car in 2 years is £1767.2
