Which representation shows a proportional relationship between x and y?

Answer:

b= 200 is not an example of a perfect square

Answer:

5 in

Step-by-step explanation:

S = 6x² is the formula and S = 150 in²

Therefore we have:

Side of the cube is 5 in

Answer:

Step-by-step explanation:

The problem statements needs to be properly formatted

3.5, -2.1, √ 9, -7/2, and√5.

let us find all square roots given in the list

√ 9= 3

√5= 2.23

hence we have 3.5, -2.1, 3, -7/2, and 2.23.

Also let us convert all fractions to decimal numbers

-7/2= -3.5

3.5, -2.1, 3, -3.5 and 2.23.

from least to greatest we have

-3.5,-2.1,2,2.23,3,3.5

or

3.5, -2.1, √ 9, -7/2, and√5.

-7/2,-2.1,√5, √9, 3.5

Answer:

x=1; y=1

Step-by-step explanation:

Step-by-step explanation:

Given:

y=-5x+6 ----------(1)

y=3x-2 ----------(2)

As L.H.S from equation 1 and 2 are equal R.H.S will also be equal

Therefore

-5x+6=3x-2

-5x-3x=-2-6

-8x=-8

x=1

put x=1 in equation (1)

y=-5×1+6

y=-5+6

y=1

Therefore , x=1 and y=1.

Answer:

d ≈ 5.64 m

Step-by-step explanation:

We are told that the pool is circular and that the area is 25 m².

Now, the longest chord that connects two points in a circle is the diameter.

Thus, the longest distance d will be the diameter

Area of circle is given by the formula;

A = πr²

Thus;

25 = πr²

r² = 25/π

r = √(25/π)

r = 5/√π

Diameter is twice the radius. Thus;

d = 2 × 5/√π

d = 10/√π

d ≈ 5.64 m

Answer:

-5x/12y

Step-by-step explanation:

Answer:

x=-6

For PA:  78-29=49

For AQ:  48+3=51

Step-by-step explanation:

The line is from left to right PAQ

It says PQ is 100 which is the whole line

PA +AQ is PQ so that means:

-13x-29-8x+3=100

-21x-26=100

-21x=126

x=-6

Plug in the x values to PA and AQ

For PA:  78-29=49

For AQ:  48+3=51

Answer:-

a ∨ ( b ∨ c )    ⇔ (a ∨ b )∨ c ⇔ (a∧b)∨c ⇔(a∧b)→c

Step-by-step explanation:

Explanation :-

we know that   b→ c ⇔ b∨c

Replacing b→ c ⇔ b ∨ c , we get

               a → b ∨ c ,

By the same rule b→ c ⇔ b∨c

                     ⇒   a ∨ ( b ∨ c )

Now

 a ∨ ( b ∨ c )    ⇔ (a ∨ b )∨ c ⇔ (a∧b)∨c ⇔(a∧b)→c

Answer:

1.   [tex]TV = 68[/tex]

2.  [tex]x = 7[/tex]

3.   [tex]x = 21[/tex]

4.    [tex]CD = 8[/tex]

Step-by-step explanation:

Solving (1):

Given

[tex]RT = 63[/tex]

[tex]RV = 131[/tex]

Required

Determine TV

To solve TV, we make use of the following formula;

[tex]RV = RT + TV[/tex]

Substitute values for RT and RV

[tex]131 = 63 + TV[/tex]

Make TV the subject of formula

[tex]TV = 131 - 63[/tex]

[tex]TV = 68[/tex]

Solving (2):

Given

[tex]MN = 26[/tex]

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

[tex]PN = 2x + 1[/tex]

Required

FInd x

To solve x, we make use of the following formula;

[tex]MN = MP + PN[/tex]

Substitute values for MP, MN and NP

[tex]26 =x + 4 + 2x + 1[/tex]

Collect Like Terms

[tex]2x + x = 26 - 4 -1[/tex]

[tex]3x = 21[/tex]

Divide both sides by 3

[tex]x = 7[/tex]

Solving (3):

Given

[tex]HM = 4x - 12[/tex]

[tex]MJ = 3x + 9[/tex]

Required

Find x

Since M is the midpoint;

[tex]HM = MJ[/tex]

This gives

[tex]4x - 12 = 3x + 9[/tex]

Collect Like Terms

[tex]4x - 3x = 12 + 9[/tex]

[tex]x = 21[/tex]

Solving (4):

Given

[tex]CE = 6x + 2[/tex]

[tex]DE = 2x + 4[/tex]

Required

FInd CD

Since D is the midpoint;

[tex]CD= DE[/tex]

and

[tex]CE = CD + DE[/tex]

Substitute CD for DE

[tex]CE = DE + DE[/tex]

[tex]CE = 2DE[/tex]

Substitute values for CE and DE

[tex]6x + 2 = 2(2x + 4)[/tex]

Open Bracket

[tex]6x + 2 = 4x + 8[/tex]

Collect Like Terms

[tex]6x - 4x = 8 - 2[/tex]

[tex]2x = 6[/tex]

Divide both sides by 2

[tex]x = 3[/tex]

Recall that;

[tex]CD= DE[/tex]

So;

[tex]CD = 2x + 4[/tex]

Substitute 2 for x

[tex]CD = 2 * 2 + 4[/tex]

[tex]CD = 4 + 4[/tex]

[tex]CD = 8[/tex]

Answer:

x=1

Step-by-step explanation:

So when it's h(5)= whatever equation you all the x in the equation to 5 and solve. When it says h(x)=0, it's asking you to find x for the equation to equal 0.

It's easy! all you have to do is set the equation to 0

so 4x-4=0

add 4 from both sides

4x = 4

divide

Answer:

k = 500 - a

Step-by-step explanation:

[tex]k + a = 500[/tex]

As we need "k" alone in one side of eqn. , we need to substract "a" on both the sides of the eqn. so that we can cancel "a" which on the left side.

[tex]k + a - a = 500 - a[/tex]

[tex] = > k = 500 - a[/tex]

Answer:

12 boxes an hour

Step-by-step explanation:

If Adsila made 9 boxes an hour for 6 hours,she made 54 boxes (9*6=54). Take how many she made away from the total (126-54=72). If Carlos made 72 boxes in 6 hours, divide 72 by 6 to get 12 (72/6=12). Carlos made 12 boxes an hour.

Answer:

Step-by-step explanation:

For sales of 's', Alan's earnings will be ...

  320 +0.05s

He wants that to be at least 600, so the inequality is ...

  320 +0.05s ≥ 600

__

Its solution is found by subtracting 320 and dividing by 0.05.

  0.05s ≥ 280

  s ≥ 5600

Alan's weekly sales must be at least $5600 for his earnings to cover his expenses.

Answer: 15/32

Step-by-step explanation:

The data that we have is:

5/8 of the vegetable sold where green.

of theses 5/8, 3/4 were string beans.

Then the 3/4 is applied to the 5/8 of green vegetables.

Then the fraction (of the total number of vegetables) that were string beans was:

F  = (3/4)*(5/8) = (3*5)/(4*8) = 15/32

Answer:

The answer is D.

Step-by-step explanation:

We have to apply Discriminant Law. When a quadratic equation, ax² + bx + c = 0 has equal roots so the discriminant will be 0. Then, you have to substitute the values into the formula :

[tex]D = {b}^{2} - 4ac[/tex]

[tex]let \: D = 0 ,a = 2,b = k,c = k[/tex]

[tex]0 = {k}^{2} - 4(2)(k)[/tex]

[tex] {k}^{2} - 8k = 0[/tex]

[tex]k(k - 8) = 0[/tex]

[tex]k = 0[/tex]

[tex]k - 8 = 0[/tex]

[tex]k = 8[/tex]

The difference between tax credit and a tax deduction is that- a tax credit reduces the amount of money you must pay, while a tax deduction reduces your taxable income.

A financial charge that is imposed on a taxpayer in order to fund government spending and public expenditures is called tax. It is imposed by a governmental organization. It is a compulsory charge.

Given is tax credit and a tax deduction.

Tax credits and a tax deductions are same in a way that they will decrease what you pay in taxes. However, the method in which each of them work is quite different. Tax deductions lower your taxable income and will reduce what you'll pay in taxes, while tax credits reduce your tax bill dollar for dollar and may even increase your refund.

Therefore, the difference between tax credit and a tax deduction is that- a tax credit reduces the amount of money you must pay, while a tax deduction reduces your taxable income.
