What dose the slope mean in ableger

1 answer:

8 0

In the equation of a straight line (when the equation is written as "y = mx + b"), theslope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis).

PLEASE HELP!!!Which statement is true? Select all that apply.

Fittoniya [83]

Answer:

"The relationship is proportional."

"The equation of the line is y = -3x"

Step-by-step explanation:

First, a proportional relationship can be written as:

y = k*x

where k is called the constant of proportionality. (or the slope)

You can see that if we take x = 0, we have

y = k*0 = 0

Then this type of line always passes through the point (0, 0).

And in the graph you can see that this line does that, then:

"The relationship is proportional." is true.

We also can see that as x increases, the value of y decreases, this must imply that k is a negative number, then:

"The slope is negative." is true.

To find the value of the slope, we can take two points that belong to the line.

I will choose:

(0, 0) and (2, -6)

For the slope, we just take the quotient between:

Δy = -6 - 0 = -6 (the difference in the y-components)

Δx = 2 - 0 = 2 (the difference in the x-components)

the slope is:

k = Δy/Δx = -6/2 = -3

Then the slope is -3, and we can write the equation as:

y = -3*x

Then:

"The equation of the line is y = -3x" is true.

If f(x) = -x^2 +5z and g (x) = 2x-4 find

ValentinkaMS [17]

Answer:

1) x=√−y+5z or x=−√−y+5z

2) g=2x-4/x

Step-by-step explanation:

explanation for first problem:

Let's solve for x.

y=−x^2+5z

Step 1: Flip the equation.

−x^2+5z=y

Step 2: Add -5z to both sides.

−x^2+5z+−5z=y+−5z

−x^2=y−5z

Step 3: Divide both sides by -1.

−x^2

−1

y−5z

−1

x2=−y+5z

Step 4: Take square root.

x=√−y+5z or x=−√−y+5z

explanation for problem 2:

Let's solve for g.

gx=2x−4

Step 1: Divide both sides by x.

gx/x = 2x-4/x

g=2x-4/x

Pls help me with this question

k0ka [10]

Answer:

height = 12 feet

Step-by-step explanation:

r (radius of circle) = 7 ft

pi = 3.14 (in this context)

v = 1/3 * $πr^{2}$ (or pi * radius squared) * h

r squared = 49 ft

v = 1/3 3.14 * 49 * h

v = 1/3 153.86 * h

3v = 153.86 * h

v = 196π

v = 615.44

3v = 1,846.32

1,846.32 = 153.86 * h

h = 12 ft.

(5+4) +10=5+(4+10) A. True B. False

Studentka2010 [4]

Answer:

A. True

Step-by-step explanation:

One of the ways to check this is solving each side of the equation.

(5+4)+10=5+(4+10)

Remember PEMDAS.

Parenthesis first.

(9)+10=5+(14)

Now, you can drop the parenthesis and add the numbers together.

9+10=19

5+14=19

19=19

This is a true statement.

Hope this helps!

If not, I am sorry.

Below is data about the labor market in the state of Northwoods. Wage Quantity Demanded Quantity Supplied $10 80,000 120,000 $9

Mars2501 [29]

Answer:

So the number of people who would be unemployed is 111111.

Step-by-step explanation:

We calculate the total number of people and how much money they will need:

$200000\cdot 10\$=2000000\$\\\\200000\cdot 9\$=1800000\$\\\\200000\cdot 8\$=1600000\$\\\\200000\cdot 7\$=1400000\$\\\\200000\cdot 6\$=1200000\$\\$

So the total number of people receiving a salary is 1000000.

A total of $ 8000000 is required for their salaries.

If the minimum wage is $ 9, we get:

$8000000:9=888888.8\\\\\\1000000-888888.8=111111.2\\$

So the number of people who would be unemployed is 111111.
