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)

Answer:

The answer is "Option C".

Step-by-step explanation:

The census is meant to count a whole population of a nation and the place, where everyone normally lives. It is a statistical method, which analyses all groups or components of its community used then for a specific particular population so not all representatives with this population. It try to collect data from everybody in the community and we're doing a census.

Answer:

[tex]y=-2x+3[/tex]

Step-by-step explanation:

Equation of straight line in slope intercept form is given as

[tex]y=mx+b[/tex]

Here

Slope of line m=-2 (for every one step on x-axis line going down 2 step on y-axis)

y-intercept b=3

[tex]y=-2x+3[/tex]

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]

Answer:

(a+b)(2x−ab+a−b)+x(a−b)+x²

Step-by-step explanation:

I can't make a good explanation, so here's a graph.

Also, this wouldn't be a proportional relationship because of exponents on the last term.

This is really a parabola.

Answer:

it is 31/20 but in mixed form it's

[tex]1 \times \frac{11}{20} [/tex]

Answer:= 87.50m

Step-by-step explanation: base × height ÷2

                                                25 ×  7     ÷    2

                                                175      ÷ 2  

                                              =   87.50

Answer:

Speed of Puck is 18 m/s

Step-by-step explanation:

Mathematically;

speed = distance/ time

The puck traveled a distance of 27 m in 1.5 seconds

The speed of the puck is thus;

27/1.5 = 18 m/s

15 pairs of combinations

Answer:

y=-1/3x+10

Step-by-step explanation:

y=3x+1

The line perpendicular would have a negative reciprocal of the slope of 3 which means that you would add a negative sign and then flip 3/1 into 1/3 resulting in -1/3 as the slope.

To find the line that passes through the point (6,8) you would plug the values into the equation y=mx+b

m=-1/3x as found above

6 is the x-value and 8 is the y-value

8=(-1/3)(6)+b

8=-2+b

Add 2 on both sides and you get b to equal 10  

Answer:

The length of rectangle is 78 and width is 46

Step-by-step explanation:

Let l be the length of rectangle and w be the width of rectangle

Then according to given statement

"The length and width of a rectangle  added together is 124"

[tex]l+w = 124[/tex]  Eqn 1

And

[tex]l-w = 32[/tex]    Eqn 2

The equation form a system of linear equation in two variables. We can use different methods to solve he system.

We will use the elimination method

Adding equation 1 and equation 2

[tex]l+w+l-w = 124+32\\2l = 156\\\frac{2l}{2} = \frac{156}{2}\\l = 78[/tex]

Putting l = 78 in equation 1

[tex]78+w = 124\\w = 124-78\\w = 46[/tex]

Hence,

The length of rectangle is 78 and width is 46

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:

[tex]3(x + 4) = 27 \\ (x + 4) = \frac{27}{3} \\ (x + 4) = 9 \\ x = (9 - 4) \\ \boxed{x = 5}✓[/tex]

Answer:

the answer is 5 because when you do PEMDAS 5+4 is 9 and then when you do 3×9 you get 27.
