To figure out if a graph is a function, we will use the vertical line test below

The vertical line test is a graphical method of determining whether a curve in the plane represents the graph of a function by visually examining the number of intersections of the curve with vertical lines.

From the first graph we can see that the vertical line cuts the points at on intersection

The Second graph is given below as

Its has two intersections on both sides of the graph

The third graph is given below as

It has two intersections on the ride hand side of the graph

The Fourth graph ios given below as

Its has two intersection on the right hand side of the graph

In conclusion,

A graph is said to be a function if one value of x has a separate value of y

Therefore,

The final answer is

The FIRST OPTION is the correct answer

Given

We are to add them together to know the total

The final answer

we have the points

(-2,6) and (-3,-7)

step 1

Find out the slope

m=(-7-6)/(-3+2)

m=-13/-1

m=13

step 2

Find out the equation in slope-intercept form

y=mx+b

we have

m=13

point (-2,6)

substitute and solve for b

6=13(-2)+b

6=-26+b

b=32

therefore

y=13x+32

step 3

Convert to standard form

AX+By=C

y=13x+32

13x-y=-32 -------> is equivalent to -13x+y=32

therefore

The length of the line segment from a to b is 6.08 units or [tex]\sqrt{37}[/tex] units.

The length is described as the distance between the two points in a line. The coordinate usually refers to the dimensions of the point with respect to the two dimension graph.

Relation between the coordinates and length:  [tex]\sqrt{(x_{1} -x_{2}) ^{2} +(y_{1} -y_{2} )^{2} }[/tex]

Now let point a be ([tex]x_{1},y_{1}[/tex]) and point b be ([tex]x_{2},y_{2}[/tex])

Thus putting values,

length = [tex]\sqrt{(3-(-3))^{2}+(4-3)^{2} }[/tex]

length = [tex]\sqrt{36+1}[/tex]    

length = [tex]\sqrt{37}[/tex]

Hence the length of ab is [tex]\sqrt{37}[/tex] or 6.08 units.

Answer: 503,000

Step-by-step explanation:

The best way to understand the concept is to look at a round to the nearest thousand example: what is 52437 rounded to the nearest thousand?

As the hundredth digit is 4, which is less than 5, the number should be rounded down to 52000. As for 52678, as the hundredth digit is 6, which is larger than 4, it will be rounded up to 53000.

From the image, we have the equation:

3x - 6 = -2x + 4

Let's solve for x:

3x - 6 = -2x + 4

Add 2x to both sides of the equation:

3x - 6 + 2x = -2x + 2x + 4

3x + 2x - 6 = 4

5x - 6 = 4

Add 6 to both sides:

5x - 6 + 6 = 4 + 6

5x = 10

Divide both sides by 5:

The probability that the sample mean will differ from the population mean by more than 1.8 mm = 0.9949

Given,

In the question:

According to the given problem the mean diameter μ= 149 mm (population mean) and the standard deviation is σ = 8mm

random sample size, n= 50 steel bolts is selected

Let the random variable that represents the diameter of steel bolts be denoted by x and from the problem we have x = 3.3mm

Let z = (x-μ) / (σ/√n ) ....(1)

using formula (1) and when the sample mean differs from the population mean by more than 1.8mm

z = (3.3 - 149) /(8/√50 )

⇒z = -2.575

The probability that the sample mean will differ from the population mean by more than 1.8 mm

P( z > -2575) = 1 - P(z< -2.575) = 1 - 0.0051 = 0.9949

Hence, The probability that the sample mean will differ from the population mean by more than 1.8 mm = 0.9949.

To solve this problem, we can use the compound interest formula

Where A represents the accrued value, P represents the invested value, r represents the interest(in decimals), n represents the amount of times the interest is compounded per unit 't' and t represents the time.

Since the unit of the time 't' is years, and the interest is compounded yearly, n = 1.

To write a percentage as a decimal, we just have to divide the percentage value by 100.

To find the amount of time t, we just have to subtract the year the money was invested from the year we want to know the money accrued.

Then, using those values on the formula, we have

The accrued value in the year 2029 will be $16,073.18.

Now, we use the point-slope formula to find the equation.

Now, we solve for y to express it in slope-intercept form.

The number of acres that are not federally owned = 3089.98 million

Land or other assets that are legally owned by the government or a government agency are referred to as government-owned property.

Federal, state, or local governments may be the owners of government-owned land, which may or may not be open to the general public without restriction.

If 14% of the land is federally owned, then 100 -14  = 86% of the land is not federally owned.

(14 *3593 ) / 100

50302 / 100 = 503.02

Federal owned land is 503.02 million acres of land.

3593 - 503.02 = 3089.98 =  (86× 3593) ÷ 100

Land not owned by Federal Government = 3089.98 million acres of land.

Answer: g(f(5)) = 352

Step-by-step explanation:

The question being asked is the same as finding g(f(5)).

What this means is to find f(5), and then plug that value into g(x) as x and solve.

f(5) = 4(5) + 1 = 20 + 1 = 21

g(f(5)) = g(21) = 21^2 - 4(21) - 5 = 441 - 84 - 5 = 357 - 5 = 352

Note: You could also find g(f(x)), and then plug 5 in as x and solve.

Start by plugging f(x) into g(x) such that you get g(x = f(x))

g(f(x)) = (4x + 1)^2 - 4(4x + 1) - 5

Now, replace x with 5 and solve to get g(f(5)).

g(f(5)) = (4(5) + 1)^2 - 4(4(5) + 1) - 5 = 352

What is an equation?

Algebra is concerned with two types of equations: polynomial equations and the particular case of linear equations. Polynomial equations have the form P(x) = 0, where P is a polynomial, while linear equations have the form ax + b = 0, where a and b are parameters, when there is only one variable. To solve equations from either family, algorithmic or geometric approaches derived from linear algebra or mathematical analysis are used. Algebra also investigates Diophantine equations with integer coefficients and solutions. The approaches employed are unique and derive from number theory. In general, these equations are complex; one frequently searches just for the existence or lack of a solution, and, if they exist, the number of solutions.

This problem is related to the linear equation and the required cost of the dryer is $425.

What is a linear equation?

If a variable's maximum power is always 1, an equation is said to be a linear equation. As a one-degree equation, it also goes by that name.

Let a washer costs be [tex]w[/tex] and a dryer costs be [tex]d[/tex].

Since the total cost of a washer and a dryer is $765, it follows:

[tex]w+d=765[/tex]                ... (1)

Further, it is given that the washer costs $85 less than the dryer, it means that:

[tex]w=d-85[/tex]                 ... (2)

Using the two linear equations (1) and (2), it follows:

[tex]d-85+d=765\\2d-85=765\\2d=765+85\\2d=850\\d=\frac{850}{2}=425[/tex]

Answer:

Step-by-step explanation:

You want the intercepts of the equation -6x +9y = -18.

There are several ways to find the intercepts. In each case, the x-intercept is the value of x that satisfies the equation when y=0, and vice versa.

For y = 0, we find the x-intercept to be ...

  -6x + 0 = -18

  x = -18/-6 = 3

The x-intercept is 3; the point at that intercept is (3, 0).

For x = 0, we find the y-intercept to be ...

  0 +9y = -18

  y = -18/9 = -2

The y-intercept is -2; the point at that intercept is (0, -2).

The intercept form of the equation for a line is ...

  x/a +y/b = 1

where 'a' is the x-intercept, and 'b' is the y-intercept.

We can get this form by dividing the original equation by -18.

  -6x/-18 +9y/-18 = 1

  x/3 +y/(-2) = 1

The x-intercept is 3; the y-intercept is -2.

Additional comment

When asked for the intercepts, it is sometimes not clear whether you are being asked for the value where the curve crosses the axis, or whether you are being asked for the coordinates of the point there.

Your previous "wrong" answer was given as point coordinates. Apparently, just the value at the axis crossing is required.

You have to have some understanding of your answer-entry and answer-checking software to tell the required form of the answer (or you can ask your teacher).

What to do?

Graph each equation on the same set of axis.

Determine the mass that makes the spring the same length.

Determine the length of that mass.

Write a sentence comparing the two springs.

Given:

f(m) = 18 + 0.4m and g(m) = 11.2 + 0.54m

Step 1

Find the x and y-intercept of both function.

f(m) = 18 + 0.4m

f(0) = 18+0.4(0) = 18

0 = 18 + 0.4m

0.4m = -18

m=-45

The x and y -intercept of the function f(m) are (0, 18) and (-45, 0) respectively.

g(m) = 11.2 + 0.54m

g(0) = 11.2 + 0.54(0)

g(0) = 11.2

0 = 11.2+ 0.54m

0.54m = -11.2

m=20.7

The x and y - intercepts are (0, 11.2) and (20.7, 0).
