What can you infer about the constant of proportionality and the unit rate? Pls help me, it’s just 7th grade math work. And yes, I will mark as Brainliest.

Step-by-step explanation:

using the graph, we can see that the line goes through points

(0, 5) and (3, -1)

this is all we need

[tex]y = mx + b\\ m = \frac{y_2-y_1}{x_2-x_1} = \frac{5-(-1)}{0-3} = -2[/tex]

[tex]y = mx + b\\5 = -2(0) + b\\b = 5\\y = -2x + 5[/tex]

Answer:

-4+2x

Step-by-step explanation:

-7+3=-4

6x-4x=2x

Answer:

-4 + 2x

Step-by-step explanation:

-7 + (+3) = -4, which is why i included a -4 in the expression

6x - 4x = 2x, which is why i included a 2x in the expression

8800

Step-by-step explanation:

Divide 3520 by 2 to get 1760

Then you multiply 5 by 1760 to get 8800

Explicación paso a paso:

Workdone = Fuerza * distancia movida en la dirección de la fuerza

Dado

Fuerza f = 40N

Distancia = 6 m

El trabajo realizado por la fuerza F es:

Trabajo hecho = 40 * 6

Trabajo terminado = 240 Nm

El trabajo realizado por la fuerza de la gravedad es el trabajo realizado por el cuerpo de 2 kg:

W = mg

W = 2 * 10

W = 20N

Trabajo realizado = 20 * 6

Trabajo terminado = 120 Nm

Answer:

A.4

Step-by-step explanation:

start at the y-intercept and work down

The answer is B) y= 7/4x

This is because when you graph it you would go up 7 and over 4- you just had to find the rise over run. I also just made sure it was correct on edmentum!

Caroline is planting her first 7 flowers in 4 minutes and then past 12 minutes, she plants 21 different flowers. That suggests that she is planting the flowers following the given equation  y=(7/4)x.

The dependent variable is defined as the variable whose evaluation of the independent variable determines the quality of the dependent variable. That is, it is consistently claimed that the word variable's estimate depends on the mathematical condition's free variable.

Let Caroline plant y flowers in x minutes.

By using the unitary method we can observe that

4 minutes  → 7 flowers

⇒ 1 minute → 7/4 flowers

⇒ x minutes → (7/4)x flowers

Hence, Caroline is planting y=(7/4)x flowers in x minutes. And y=(7/4)x this equation represents the variation perfectly.

NOTE: We took the number of flowers planted as y because it is a dependent variable. The number of flowers depends on the time elapsed.

Answer:

it is ether B or D cuz

Step-by-step explanation:

4+2+1=7  marbles

(4/1)+(2/1)+(1/1)=7/21

divide 21 by 7 that would = 3

Answer:

The slope would be 1.

Step-by-step explanation:

The slope would be one becuase the equation would be y=1x+5.

Answer:

the equation would be y=x+5

so the slope is 1

Answer:

1284 gallons

Step-by-step explanation:

The swimming pool already contained 486 gallons.

Then, Jaxson filled the pool for 95 minutes, so, the total amount of water in the pool at the end of 95 minutes = 486 + filled amount in 95 minutes.

The rate of filling water is 8.4 gallons per minute. i.e

In 1 minute, the amount of water filled = 8.4 gallons.

So, by using the elementary method, in 95 minutes, the amount of water filled = 8.4 x 95 = 798 gallons.

So, the total amount of water in the pool at the end of 95 minutes

=486 + 798 = 1284 gallons.

Answer:

The actual ages of all runners are needed to decide.

Answer:

First:

Convert any mixed numbers to fractions.

Then your initial equation becomes:

−3/8÷−11/4

Applying the fractions formula for division,

=−3×4 / 8×−11

=−12/88

Simplifying -12/-88, the answer is

=3/22

Answer: The third side of the triangle must be greater than the sum of sides 11 and 16.

Step-by-step explanation: "Triangle Inequality Theorem." This theorem states that any side of a triangle must be shorter than the other two sides added together.

Answer:

Step-by-step explanation:

The set up will form a right  angles triangle:

First we need to get the angle of elevation of the first ladder using SOH, CAH, TOA

The length of the ladder will be the hypotenuse = 10foot

The opposite will be the height of the building = 8ft

Using Sin(theta) = opposite/hyp

sin Theta = 8/10

theta = sin^{-1}0.8

theta = 53.13°

If the length of the ladder is now 25 foot, the height of the building will be calculated as shown;

sin Theta = h/25

sin53.13 = h/25

h = 25sin53.13

h = 19.99feet

Hence the height of the building will be 19.99feet

Answer:

10.8 units

Step-by-step explanation:

Step-by-step explanation:

To find the distance between two points, use the distance formula.

Answer:

a + 112 + 33 = 180 ( sum of interior angles of tria

or a + 145 = 180 - ngle is 180 degrees)

or a = 180 - 145

or a = 35 .

similarily,

c + 43 + 71 = 180

or c + 114 = 180

or c = 180 - 114

or c = 66 .

and ,

a + 71 + b = 180 ( sum of angles in straight line is or, 35 +71 + b = 180 180 degrees)

or , b + 106 = 180

or, b = 180 - 106

or, b = 74 .

Answer: 1/2

Step-by-step explanation:

1. Find the least common denominator (14) and multiply the numerator as much as the denominator

4/14 + 3/14

2. Add the 2 fractions together

4/14 + 3/14 = 7/14

3. Simplify

7/14 divided by 7 = 1/2

The answer is 1/2

;Answer:

The answer is below

Step-by-step explanation:

The PTA is trying to raise money for an end of the year carnival for a local

school. They are selling t-shirts, s, for fundraisers. Their revenue equation is

represented by the equation below. As a reminder, the revenue equation

describes how much money is brought in during the fundraiser: r(s) = - .1552 +30s

Their expenses equation is represented by: e(s) = 3s + 200.

A. Find the value of r(s) = e(s)

I

B. Explain what this means in the context of the problem.

Solution:

The revenue is the amount of money gotten by selling goods and products while expenses is the amount of money spent to produce the goods or products.

The revenue is given as:

r(s) = - 0.1552 +30s

While the expenses is given as:

e(s) = 3s + 200.

Since r(s) = e(s), therefore:

3s + 200 = -0.1552 + 30s

30s - 3s = 200 + 0.1552

27s = 200.1552

s = 7.4

s ≈ 7

At break even the expenses and revenue are equal to each other.

This means that if 7 t shirts are produced then the PTA would be at break even.

-23

Step-by-step explanation:

x2−x+6=0

Step 1: Find discriminant with a=1, b=-1, c=6.

b2−4ac

=(−1)2−4(1)(6)

=−23

Answer:

−23

Answer:

no solution

Step-by-step explanation

[tex]x^{2}-x+6=(x^{2}-2.\frac{1}{2}x+\frac{1}{4})+6-\frac{1}{4}=(x-\frac{1}{2})^{2}+\frac{23}{4}[/tex]

see : [tex](x-\frac{1}{2})^{2}\geq 0 => (x-\frac{1}{2})^{2}+\frac{23}{4}\geq 0+\frac{23}{4}>0[/tex]

but x² - x + 6 =0

=> it is unreasonable

Answer:

14 - (y x 15)

Step-by-step explanation:

This is the number because:

1) 14 minus means 14 subtracted from the product of a number and 15

2) The product of a number and 15 is a variable multiplied with 15

3) Finally, if we put these together, we get 14 - (y x 15)

Hope this helps!
