Does the graph represent a function? Choose the correct descriptor.

Answer:

y=16, x=24

Step-by-step explanation:

First simplify: x-(1/2x+4)=8

Isolate x for 1/2x-4=8

Add 4 to both sides:

1/2-4+4=8+4

Simplify :1/2=12

Multiply both sides by 2:

2*1/2x=12*2

Simplify:

x=24

Substitute x=24:

y=1/2*24+4

1/2*24+4=16

1/2*24=12

12+4

Add the numbers: 12+4=16

y=16

The solutions to the systems of equations are:

y=16,x=24

Answer:

It is important because they are the basics of algebra. Almost every algebraic problem you will ever solve is based on these fundamental properties. In equations, we almost never know every part of it so we will need variables to substitute the unknown amount in an equation. Variables are used for basically every equation/problem in algebra. Inequalities are not as important as variables but are still really important. Inequalities are basically comparing numbers. And in algebra when they add variables into an inequality, the inequality will help lower the number of possible values of said variable. And exponents are just a basic operation in algebra. Just like learning addition and subtraction. It is like a quicker and less complicated way of multiplying numbers.

Answer:

60

Step-by-step explanation:

90 divided by 30 is 3, so you would multiply 20 by 3 to get your answer of 60.

Hope this helps :)

Answer:

560

Step-by-step Explanation

Since, 476 students make 85%.

Therefore, let x students will make 100%.

[tex] \frac{476}{85} = \frac{x}{100} \\ \\ x = \frac{476 \times 100}{85} \\ \\ x = \frac{47600}{85} \\ \\ x = {560} [/tex]

Answer:

W = 16.5 meters

Step-by-step explanation:

let w be the width and then the length is w+2

Perimeter = 70 = 2w + 2(w+2)

70 = 2w + 2w + 4

4w = 66

w = 16.5 meters

Answer:

A line segment has two endpoints. It contains these endpoints and all the points of the line between them. A segment is named by its two endpoints. A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray.

Answer: 14

Step-by-step explanation:

1.75x -2 + 1.75x -2 + 1.75x -2 =67.5

5.25x-6= 67.5

5.25x =73 .5

X = 14

Answer:

1.75x-2= -3.14

-3.14 x 1.75= -5.495 -2= -7.495

x=3.14

Answer:

25 + x = 44

Step-by-step explanation:

Substitute the words with the math symbols.

25 more than a number x is the same as 44

more than means to +

is the same as means =

25 more than a number x is the same as 44

25          +                       x       =  44    

25 + x = 44

Answer:

System has equal number of unknowns and equations.

Manipulation easily yielded expressions for 4 of the 7 unknowns.

However it seems that the remaining 3 unknowns x,y,z are not fixed by the equations. Different combinations (x0,y0,z0) seem possible without violating the system equations.

Is this possible, or did I most probably make a mistake in counting degrees of freedom?

Answer:

2550.5

Step-by-step explanation:

We have a circle and are asked to find the area.

We know the diameter already, but the formula to find area requires a raidus, which is unknown to us yet.

To find radius, all you need to do is follow [tex]\frac{d}{2}[/tex]. D being diameter.

D = 57.

[tex]\frac{57}{2}= 28.5[/tex]

The radius is 28.5, now do the formula of area.

[tex]A = \pi *r^2[/tex]

[tex]A = \pi *28.5^2[/tex]

[tex]28.5^2[/tex]

[tex]812.25[/tex]

[tex]A=\pi *812.25[/tex]

[tex]A=3.14 * 812.25[/tex]

[tex]A = 2550.465[/tex]

Now we need to round to the nearest tenths, since 6 is the knowledge that we round up, round up.

[tex]2550.5[/tex]
