For what value(s) of k will the relation not be a function?
1.B={(k^2-5k,10),(k+7,4)}
2.R={(k^3-5k^2+3k,-5),(-k,4)}
3.S={(|k+1|+2,4),(8,7)}
Solving any helps, but if you can solve all of them I would be so grateful and I will mark brainliest.

Answer:

The answer is 2

Step-by-step explanation:

Multiply the numerator and denominator by the conjugate.

Answer:

3

Step-by-step explanation:

29-2=27

27/3=3

Answer:

Each costs $3.

Step-by-step explanation:

To find out how much Brody spent on the beakers in general, you need to subtract the original amount with the new amount. So, you would do 29-2 or $27. Now that you know how much he spent, you need to know how much each costs. Of course each beaker has to cost the same so you would divide. You would do 27/9 and would come up with $3 as your answer. Hope this helped! :)

Answer:

C.

Step-by-step explanation:

The question states that a LINE is reflected, just with this information we know that A. is incorrect because it is curved.

At first, when looking at B., it seems as though it could work, until you notice that it starts somewhere, but doesn't end, thus it is not a LINE. So, we can count B as incorrect as well.

When looking at C, it it a straight line, and has a beginning and and end, which means that so far, it is the most likely the line.

Then, we look at D. When looking at D, we can tell that it is a straight line, however, it has no beginning and no end, thus it can't be the answer.

Now, we know that C is the only possible answer for this question.

Step-by-step explanation:

Surface area = perimeter * height

Answer:

y = -1x - 4

Step-by-step explanation:

In the slope intercept form, the m is the slope and the b is the y-intercept.

y=2x+5-2x+5

y=x+0

y=+2.5

y=2.5

y=2.5

hope this helps!!

Answer:

Step-by-step explanation:

y = 4x + 5

It is in y = mx + c form

Slope (m) = 4

2y = 8x + 15             {Divide both sides by 2}

[tex]\frac{2y}{2}=\frac{8}{2}x+\frac{15}{2}\\\\y = 4x +\frac{15}{2}[/tex]

Slope = 4

If two lines have same slope, then they are parallel lines.

As you know, parallel lines have never intersect, this system of linear equations have no solution.

Answer:

12

Step-by-step explanation:

[tex]\sqrt[3]{1728} = 12[/tex]

12 x 12 x 12 = 1728

Answer:

576

Step-by-step explanation:

1728/3

17-15= 2

bring down the "2" and you get 22

Then you do 22-21= 1

bring down the "8"

Then you have 18-18=0

576

Answer:

18.58 cm

Step-by-step explanation:

8^2 - 6^2 = sqrt 28

sqrt 28 = 5.29

8 + 5.29 + 5.29 = 18.58

Answer:

195.6 inches squared

Step-by-step explanation:

First we find the value of one of the big triangles.

(14*8*0.5)

56

Next, we find the value of the three of them combined.

56+56+56 or 56*3

168

Now, we find the value of the smaller triangle.

(6.9*8*0.5)

27.6

Because we only have one small triangle, we don't need to do what we did with the other one now.

The last step is to add the area of the three triangles with the smaller triangle.

168+27.6

195.6

The surface area of the (shape...?) is going to be 195.6 in. squared.

Answer:

by dividing 325 by 48.

The answer comes out to 6.77

But since the number of buses must be a whole number, we will need 7 buses to carry the 325 students and teachers on a field trip.

so the answer is 7 buses

Answer:

the width is 2 kilometers

Step-by-step explanation:

total area: 3/2 (kilometers^2)

length: 3/4 (kilometers)

in a rectangle the area is the length multiplied by the width/height

so:

divide 3/4 from both sides to isolate the width:

[tex]\frac{\frac{3}{2}}{\frac{3}{4}} = \frac{\frac{3}{4}w}{\frac{3}{4}}[/tex]

[tex]2=w[/tex]   which is the same as:   [tex]w=2[/tex]

then just add the units on the end and you're done!

Answer:

10

Step-by-step explanation:

20-(5×2)

5×2=10

20-10=10

Answer:

a = -5

Step-by-step explanation:

a = 1/2(-10) + 3^2 - (-1) - 10

a = -5 + 3^2 - (-1) -10

a = -5 + 9 - (-1) - 10

a = 4 - (-1) - 10

a = 4 + 1 - 10

a = 5 - 10

a = -5

x = -1y = 3

z = -10

a = -5

Answer:

years 1–4: 62.4 bass per year

years 5–8: 67.6 bass per year

Step-by-step explanation:

If the population in year n is ...

 p(n) = 3000·1.02^n

then the average rate of change from year 1 to year 4 is ...

 (p(4) -p(1))/(4 -1) = 3000(1.02^4 -1.02^1)/3 = 1020·(1.02^3 -1) ≈ 62.4

The average rate of change for years 1–4 is 62.4 bass per year.

___

For years 5–8, the rate of change is similarly computed:

 (p(8) -p(5))/(8 -5) = 3000(1.02^8 -1.02^5)/3 = 1000·1.02^5·(1.02^3 -1) ≈ 67.6

The average rate of change for years 5–8 is 67.6 bass per year.
