Answer:
[tex] y = \frac{3}{10} x[/tex]
Step-by-step explanation:
[tex]y - 3 = \frac{3}{10} (x - 10) \\ \\ y - 3 = \frac{3}{10} x - \frac{3}{10} \times 10 \\ \\y - 3 = \frac{3}{10} x - 3 \\ \\y = \frac{3}{10} x - 3 + 3 \\ \\ y = \frac{3}{10} x + 0 \\ \\ \purple{ \bold{ y = \frac{3}{10} x}} \\ is \: the \: required \: equation[/tex]

Solve 3(x+4) =27
What is x?
Answer:
[tex]3(x + 4) = 27 \\ (x + 4) = \frac{27}{3} \\ (x + 4) = 9 \\ x = (9 - 4) \\ \boxed{x = 5}✓[/tex]
x=5 is the right answer.Answer:
the answer is 5 because when you do PEMDAS 5+4 is 9 and then when you do 3×9 you get 27.
Step-by-step explanation:
x=5

What is algebra?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.

When we take a census, we attempt to collect data from (a) a stratified random sample. (b) every individual selected in an SRS. (c) every individual in the population. (d) a voluntary response sample. (e) a convenience sample.
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.
the graph for the equation y=2x+4 is shown below if another poisonous graph so that the system has one solution which equation could that be? y=2x-4 y=2(x+2) y=2(x-4( y=x+4)
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:
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.

Write the standard form of the equation of the line through the given point with the given slope. Simplify as much as possible.
Point: (−1,0)
Slope: −2/3
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]

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:
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)
