Answer:

B. 5 m/s

Step-by-step explanation:

Formula for constant velocity

[tex]v=\frac{\Delta x}{\Delta t}[/tex]

plug in the values you have:

[tex]v = \frac{400}{80} = 5\frac{m}{s}[/tex]

so B. 5 m/s

Answer:

p = - 5, p = - 1

Step-by-step explanation:

Given

[tex]\frac{3p}{p-5}[/tex] - [tex]\frac{2}{p+3}[/tex] = [tex]\frac{p}{p+3}[/tex]

Multiply through by the LCM of (p - 5)(p + 3)

3p(p + 3) - 2(p - 5) = p(p - 5) ← distribute parenthesis

3p² + 9p - 2p + 10 = p² - 5p

3p² + 7p + 10 = p² - 5p ( subtract p² - 5p from both sides )

2p² + 12p + 10 = 0 ← divide through by 2

p² + 6p + 5 = 0 ← in standard form

(p + 1)(p + 5) = 0 ← in factored form

Equate each factor to zero and solve for p

p + 1 = 0 ⇒ p = - 1

p + 5 = 0 ⇒ p = - 5

Answer:

The number of links in a chain

Step-by-step explanation:

An independent variable is any variable whose value or identity does not in any way affect the event of another variable in the system. A dependent variable is a variable whose value or identity depends on one or more variables in the system.

From the information given:

The length of the chain is an independent variable while the number of links that depends on the length of the chain is the dependent variable.

Answer:

y-intercept = 3

Step-by-step explanation:

The given equation is :

6x-5y=-15

We can rewrite it ib slope-intercept form as follows :

Dividing both sides by 5

[tex]\dfrac{6x}{5}-y=\dfrac{-15}{5}\\\\\dfrac{6x}{5}-y=-3\\\\\dfrac{6x}{5}+3=y[/tex] .....(1)

The general equation of slope-intercept form is:

y = mx +c  ....(2)

On comparing equation (1) and (2) we get :

m = 6/5

c = 3

Hence, the y intercept of the graph of the equation is 3.

Equality Properties

Step-by-step explanation:

Step 1: Define equation

2(5x + 6) = 4(2x + 5)

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 52 does indeed equal 52.

∴ x = 4 is a solution of the equation.

Answer:

I can`t really see the question that well, but if I understand correctly here`s the first few.

1. Subtraction

2. Addition

3. Addition

4. Subtraction

5. Addition

6. Subtraction

It looks like its asking what is happening in those situations (is the number being added or subtracted). Sorry if that`s not much help

-10x+28

first you must distribute -3

then you combine like terms and you end up with -10×+28

Answer:

infinite

Step-by-step explanation:

Answer:

A single cheeseburger order cost $1.23

A single fries order cost $1.28

Step-by-step explanation:

Let the cost of cheeseburgers be c and the cost of fries be f

Mathematically;

4c + 3f = 10.75 ••••(i)

Secondly;

5c + 2f = 11.2 ••••(ii)

We have two equations to solve simultaneously;

Multiply i by 2 and ii by 3

8c + 6f = 21.5

15c + 6f = 33.6

Subtract ii from i

-7c = -12.1

c = 1.73

Recall;

5c + 2f = 11.2

5(1.73) + 2f = 11.2

2f = 11.2-8.65

2f = 2.55

f = 2.55/2

f = 1.28

Answer:

Step 2 is incoreect.

Step-by-step explanation:

Cost of Naty's dress = $24.95

Cost of Naty's skirt = $14.95

The sales clerk said the total cost including 9.5% sale tax was $49.40.

Step 1 is correct i.e. 24.95 + 14.95 = 39.90

In step 2, he added 39.90 and 9.5. This is the wrong step. He directly added 9.5 but he have to add 9.5% i.e. 0.095.

Cost = 39.90 + 0.095

C = $39.995

Step 2 is incorrect.

Answer:

The line goes the through the origin

The line is sloping upward

The x-intercept is 0

Step-by-step explanation:

step 1

Find the equation of the line in point slope form

we have

substitute

step 2

Convert to slope intercept form

isolate the variable y

Applying the distributive property right side

The line represent a direct variation (the line passes though the origin)

step 3

Verify each statement

case a) The line is horizontal

The statement is false

Because a horizontal line has a slope equal to zero and this line has slope equal to m=3/4

case b) The line goes the through the origin

The statement is true

Because the line represent a direct variation

case c) The point (3,4) lies on the line

The statement is false

Because the ordered pair not satisfy the equation

Verify

For x=3, y=4

substitute in the equation

----> is not true

so

the ordered pair not satisfy the equation

therefore

The ordered pair not lies on the line

case d) The line is sloping upward

The statement is true

Because the slope is positive (is an increasing function)

case e) The x-intercept is 0

The statement is true

Because in a proportional relationship the x-intercept and the y-intercept are equal to zero
