The table below shows a proportional relationship between s and t . Which equation represents the relationship between s and t?

Answers

Answer:

[tex] s = 7t [/tex]

Step-by-step explanation:

The table given shows that both variables are directly proportional to each other. That is, as s variable increases, y variable also increases.

Equation to represent this direct proportion would be:

[tex] s = kt [/tex],

where, k = constant of proportionality.

Let's find k from the table given.

Let's use any pair values of of s and t given in the table. Say, s = 21, t = 3

[tex] s = kt [/tex]

[tex] 21 = k3 [/tex]

Divide both sides by 3

[tex] \frac{21}{3} = \frac{k3}{3} [/tex]

[tex] 7 = k [/tex]

[tex] k = 7 [/tex]

Plug in k = 3 into [tex] s = kt [/tex]:

[tex] s = 7t [/tex]

For a function j(x), the difference quotient is 3x2 + 3xh + h2. What is the average rate of change of j(x) over the interval [–1, 6]?

15

31

Answers

Answer:

31 is correct guys

Step-by-step explanation:

Since the data is incomplete, for the given question the required average rate of change is given by 15 + 3h.

Given that,
For a function j(x), the difference quotient is 3x2 + 3xh + h2.

The average rate of change of j(x) over the interval [–1, 6] is to be determined.

What are functions?

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is independent while Y is the dependent variable.

Here, the average rate of change = f(6) - f(-1) / (6 + 1)
So,
f(6) = 108 + 18h + h²
f(-1) = 3 - 3h + h²

Now,
average rate of change = [(108 + 18h + h²) - (3 - 3h + h²)]/(7)
                                        = [105 + 21 h ] / 7
                                         =   15 + 3h

Thus,  the required average rate of change is given by 15 + 3h.

Step-by-step explanation:

Kelsey graphed the equation y = 3x + 1 as shown below.

On a coordinate plane, a line goes through points (negative 3, 0) and (0, 3).

Which describes Kelsey’s error?
Kelsey graphed the y-intercept on the x-axis.
Kelsey graphed –3 instead of 3 as the y-intercept.
Kelsey graphed the slope as up 1 right 1 instead of up 1 left 1.
Kelsey graphed the slope as the y-intercept and the y-intercept as the slope.

Answers

Answer:

D. Kelsey graphed the slope as the y-intercept and the y-intercept as the slope.

Step-by-step explanation:

The equation to graph was : y= 3x + 1 where the slope is 3 and the y-intercept is 1

However, Kelsey graph line passes through points (-3, 0)and (0, 3).From these points the equation of the line is;

m=Δy/Δx  where

m=the slope of the graph

Δy= 3-0 =3

Δx= 0--3 =3

m=3/3 = 1

The equation of the line should be;

m=Δy/Δx

1=y-3/x-0

1x= y-3

3+1x= y

y= 1x + 3 ----------where the slope is 1 and y-intercept is 3

So you can see here that in the original equation, the slope m is 3 and y-intercept is 1 as shown in the first attached graph.

While in the Kelsey's graph, the slope is 1 and the y-intercept is 3 as in the second attached graph.

Thus, the correct answer is D : Kelsey graphed the slope,3 as the y-intercept and the y-intercept,1, as the slope.

Answer choice A is incorrect because Kelsey didnot graph the y-intercept, 1 on the x-axis but graphed point (-3,0) on the x-axis.

Answer choice B is incorrect because on Kelsey's equation the y-intercept is 3 and not -3. i.e. y=1x + 3

Answer choice C is incorrect because Kelsey graphed the slope as up 1 right 1 which is okay per the equation , y=1x+3.However, this incorrect because the correct graph has a slope of 3.

Mary Jo takes her son to get a haircut at the barbershop. The total cost of the haircut is $12.60, including a 20% tip. How much was the haircut before the tip?

Answers

Based on the total cost of the haircut with the tip included, the cost of the haircut before the tip was $10.50

How to find the cost of the haircut?

The cost of the haircut give of $12.60 is merely the cost of the haircut including the 20% tip.

To find the cost of the haircut before the tip was included, assume that it is x. The relevant expression would then be:

Total cost including tip = x × (1 + tip percentage)

Solving for the haircut cost before the tip gives:

12.60 = x ( 1 + 20%)

12.60 = 1.20x

x = 12.60 / 1.20

x = $10.50

How is this math I don’t understand

3x square - 6x + 3=0

Answers

Answer: 1

Step-by-step explanation:

First you need to multiply 3 x 3 (9), because that's all 3 squared means.

Now the equation should be 9x-6x+3=0

Next we need to combine like terms. Do 9x - 6x which should give you 3x

Now your equations should be 3x+3=0

Now for the somewhat harder part...

Under the three (the one without the x) write -3 and under the zero write the same thing.  the +3-3 cancels out so just put a line or something across it.

0-3= -3

so now you should have...

3x=-3    ignore the 3x, at this point it's useless in getting the answer because it would cancel out.

-3 divided by -3  is 1 because a negative (-)  divided by a negative (-) equals a positive (+).

The answer should be  x = 1

After the data are input as​ 1, 2,​ 3, or​ 4 the data still be qualitative.

Match each part of this algebraic expression with its appropriate description 12.1x - 4.7y + 6x + 1/6

Answers

Answer:Terms, like terms, constant(s),Variable (s),Coefficient(s)

Step-by-step explanation: 18.1x,4.7 and 1/6=Terms

The matched part with the respective appropriate description:

1) x and y → Variable(s)

2) 1/6 →  Constant(s)

3) 12.1, 4.7, and 6 →  Coefficient(s)

4) 12.1x and 6x →  Like Terms

5) 12.1x, 4.7y, and 1/6 →  Terms

What is an expression?

One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.

We have the algebraic expression,

12.1x - 4.7y + 6x + 1/6.

From the definition,

x and y are the two variables.

And 12.1, 6 and -4.7 are the numbers in front of the variables.

So, 12.1, 6 and -4.7 are the coefficients.

And 1/6 is the constant.

So, 1) x and y → Variable(s)

2) 1/6 →  Constant(s)

3) 12.1, 4.7, and 6 →  Coefficient(s)

4) 12.1x and 6x →  Like Terms

5) 12.1x, 4.7y, and 1/6 →  Terms

Therefore, each part of the algebraic expression matched with its appropriate description.
