relationship between x and y.

X | 2 | 4 | 6 | 8 |

_______________

Y | 10 | 20 | 30 | 40 | I tried to make the table

Answer: k = _, y =

Answer:

The answer to this problem is -24/5.

Answer:

x=-9

Step-by-step explanation:

6x=-54

Divide both sides by 6.

-54/6 = -9

x=-9

Answer:

If she puts 0 in the box she would have a direct variation.

Step-by-step explanation:

 Given : Lydia writes the equation y = 5x - __ with a missing value.

She puts a value in the box and says that the equation represents a direct variation.We have to choose the correct option from the given options that explain that  the equation could represent a direct variation.When two variables are such that one is a constant multiple of other, we said they are in Direct variation.

That is in form of y = ax , here y and x are in direct variation.Consider the given equation y = 5x  - __

For the equation to be in direct variation the value of missing term has to be 0.

then equation becomes,y = 5x

Thus, If she puts 0 in the box she would have a direct variation.

Option (a) is correct.

Answer:

4,10

Step-by-step explanation:

We want where they both overlap

X must be greater than 0

We cannot have parts of figures so we must have whole numbers

(6,9) is too large

Answer:

A

Step-by-step explanation:

The solution set is the purple region. The intersection lies at (4,10)

The region is towards left of x=4 so it can't be D

x and y have to be non-negatve integers. So it can't be B or C

Answer:

80

Step-by-step explanation:

if 1=40

2 = x

1*x=2*40

x=80

Answer:

80 ounces

Step-by-step explanation:

Let x ounces of gas is needed for 3 ounces of oil.

[tex] \therefore \: \frac{40}{1} = \frac{x}{2} \\ \therefore \: x = 40 \times 2 \\ \huge \purple{ \boxed{\therefore \: x = 80 \: ounces}} \: [/tex]

Answer:

yes, (2,3) is a solution to both equations

Step-by-step explanation:

1. since both expressions are equal to [tex]y[/tex], set [tex]x+1[/tex] and [tex]-x+5[/tex] equal to each other

[tex]x+1=-x+5[/tex]

2. solve

[tex]x=-x+4[/tex]

[tex]2x=4[/tex]

[tex]x=2[/tex]

3. substitute the value of x into the equations

[tex]y=2+1[/tex]

[tex]y=-2+5[/tex]

4. solve

[tex]3=5\\3=5[/tex]

Answer:

The other two numbers depend on what type of triangle it is.

Step-by-step explanation:

if if it is isosceles and may vary however if it is scalene the measures of the other two angles can vary greatly and it will not likely be 45 degrees to 45 degrees.

Unimodal means one hump; symmetric means there's a central axis of symmetry, here at x=4.  

Answer: B. Unimodal symmetric

Answer:

123

Step-by-step explanation:

to find the current value of one share just do this

23/100*100=23 so just add 23 on 100 and you will get 123 which is the current value of one share.

Answer:

Tim's box volume is 27 times greater than Emmy's.

Step-by-step explanation:

The volume of a cube is given by the following expression:

volume = l³

Since Emmy's cube have a 3 centimeters long edge, then it's volume is:

volume1 = 3³ = 27 cm³

On the other hand Tim's cube has an edge that is 3 times as long as Emmy's, so it's 9 centimeters long. Therefore it's volume is:

volume2 = 9³ = 729 cm³

The relation between the volume is given by:

ratio = volume2/volume1 = 729/27 = 27

Tim's box volume is 27 times greater than Emmy's.

Answer:

I'm pretty sure it's 14 not sure but positive

Answer:

None of them can be a solution

Step-by-step explanation:

Work Shown:

a = first term = 1

r = 0.8 = common ratio

We know the common ratio is 0.8 because we multiply this common ratio by each term to get the next term. The easiest to spot this is going from term1 to term2. Put another way, term2/term1 = 0.8/1 = 0.8 is our common ratio.

The general form of the nth term of a geometric sequence is [tex]a(r)^{n-1}[/tex] and because the last term has an exponent of 19, this means n-1 = 19 solves to n = 20. Therefore, we are summing exactly n = 20 terms here.

Use the formula below to take a shortcut rather than painstakingly find all 20 terms and then summing them.

[tex]S = \frac{a*(1-r^n)}{1-r}\\\\S = \frac{1*(1-0.8^20)}{1-0.8}\\\\S \approx \frac{1*(1-0.01152921504607)}{1-0.8}\\\\S \approx \frac{1*(0.98847078495393)}{0.2}\\\\S \approx \frac{0.98847078495393}{0.2}\\\\S \approx 4.94235392476964\\\\[/tex]

This value is approximate.

To check your answer, you could type the following into your calculator

1+0.8+0.8^2+0.8^3+0.8^4+0.8^5+0.8^6+0.8^7+0.8^8+0.8^9+0.8^10+0.8^11+0.8^12+0.8^13+0.8^14+0.8^15+0.8^16+0.8^17+0.8^18+0.8^19

Though as you can see, this is very tedious to type in. This is why the formula in the previous section above is preferred.

Step-by-step explanation: The dots are closest to the line instead of being more scattered like the other answers, therefore the answer is x.

Answer:

m<ABE = 115.5°

m<DBE= 25.5°

Step-by-step explanation:

m<DBC= 90°

m<DBE + m<EBC= 90°

m<DBE +64.5°= 90°

m<DBE = 90°-64.5°

m<DBE = 25.5°

m<ABE = m<ABD + m<DBE = 90°+25.5° = 115.5°
