Answer:

The relation is a function

Step-by-step explanation:

Given

[tex](1, 2), (2, -1), (3,0), (4, 1),\ and\ (5, 1)[/tex]

Required

Determine if the points is a function or not

A relation can be expressed as: [tex](x_1,y_1), (x_2,y_2),(x_3,y_3)......(x_n,y_n)[/tex]

Where

[tex]x = domain[/tex]

[tex]y = range[/tex]

When any domain element occurs more than once, then the relation is not a function.

The domain of the above points are:

[tex]x = \{1,2,3,4,5\}[/tex]

In this case, no domain occur more than once; in other words, no x value occur more than once

Hence, the relation is a function

Answer:

[tex]\frac{6x-4}{x}[/tex]

Step-by-step explanation:

(5 x 6)(3x - 2) = 15xn

30(3x - 2) = 15xn

[tex]\frac{2}{1}[/tex] * (3x - 2) = ([tex]\frac{1}{2}[/tex]xn) * [tex]\frac{2}{1}[/tex]

6x - 4 = xn

n = [tex]\frac{6x-4}{x}[/tex]

You can't cross the 'x' out of the numerator or denominator because of the - 4 in the numerator.

Answer:

a

Step-by-step explanation:

the answer is a because every week it shows (shows on the graph) that he is earning 6 dollars.

Answer:

A

Step-by-step explanation:

The formula for slope is [ y2-y1/x2-x1 ] and we can use the points (0, 0) and (5, 30) to solve.

30-0/5-0

30/5

6/1

6

Now that we know what the slope is, we can eliminate C and D.

This means that he saves around $6 per week. With this being said, we can eliminate B as well.

Best of Luck!

Answer:

X= 43/3

Step-by-step explanation:

-1/4 x 5 = 3/4x - 12

-5/4=3/4x -12

-5=3x - 48

-3x-5 = -48

-3x = -48 + 5

-3x= -43

-3 x= -43

X= 43/3

Answer:

It would be B

Step-by-step explanation:

8/3=2.66666666667

meaning x=8/3

Answer:

x² + (y + 5)² = 100

Step-by-step explanation:

If the center of the circle is 5 units below the origin, its x coordinate is 0 and its y-coordinate is -5. So, the center of the circle is at (0, -5).

Using the equation of a circle with center (h, k)

(x - h)² + (y - k)² = r² where r = radius of the circle.

Given that r = 10 units, and substituting the values of the other variables into the equation, we have

(x - h)² + (y - k)² = r²

(x - 0)² + (y - (-5))² = 10²

x² + (y + 5)² = 100

which is the equation of the circle.

Answer:(c)

Step-by-step explanation:

Given

the radius of circle=10 units

The center is 5 units below the origin i.e. (0,-5) is the center

The general equation of a circle is

[tex](x-a)^2+(y-b)^2=r^2\quad [\text{Where, (a,b) is the center of the circle and r is radius}][/tex]

Putting values

[tex](x-0)^2+(y-(-5))^2=10^2\\(x)^2+(y+5)^2=100[/tex]

Second last option is correct

Answer:

125πkm

Step-by-step explanation:

The figure shown is a cylinder :

Volume of a cylinder is obtained using tbe relation :

V = πr²h

Where ; r = Radius ; h = height

r = 5km ; height = 5km

Hence,

V = π * 5² * 5

V = 25 * 5 * π

V = 125πkm

Answer:

490km

Step-by-step explanation:

70km/hrs for 7hrs

so if the pigeon flies 70km in one hour we just have to multiply 70 by 7 to get 7hours.

70x7=490km

That means the pigeon flies 490km in 7hrs

Answer:

1,420 milligrams

Step-by-step explanation:

We know there are 100 centigrams in 1 gram, and there are 10 milligrams in a centigrams. That would mean there are 1,000 milligrams in 1 gram (100 * 10 = 1000).

As a result, all you need to do is multiply 1.42 by 1000 to get the amount of milligrams.

1.42 * 1000

Alternatively, to make 1.42 a whole number first, multiply by 100, then add a zero. (That's the other 10!)

(1.42 * 100) * 10

142 * 10

There are 1,420 milligrams in 1.42 grams.

Answer: L = 2m+3

Step-by-step explanation: The area of a rectangle is found using the formula A=L*W. The area A=12m+18. The width is W=6. The length will be the expression where 6 times it gives 12m+18. The expression is 2m+3 since 6(2m+3) = 12m+18.

Answer:

C) 0.57÷5=0.114

Step-by-step explanation:

Which quotient shows the decimal placed correctly?

Solving for each of the option

A) we are told that:6÷0.5=1.2

Hence: 6/0.5

= 12

Option A is wrong

B) we are told that: 0.64÷2=3.2

Hence: 0.64/2

= 0.32

Option B is wrong

C) we are told that: 0.57÷5=0.114

Hence: 0.57/5

= 0.114

Option C is correct

D) we are told that: 1.08÷0.3=0.36

Hence = 1.08/0.3

= 3.6

Option D is wrong

Therefore, option C is the only correct Option where the quotient shows the decimal placed correctly

Answer:

y=-x+8

Step-by-step explanation:

Plug in (7,1)

Step-by-step explanation:

Imagine lying out 2 sticks with lengths 9 and 12

on the ground. The maximum length you can

get is by putting them in a straight line. (9 + 12 = 21)

However, 21 is less than 24, which is

supposed to be the 3rd side of the triangle.

Hence the set 9, 12, 24 cannot form a triangle.
