Answer:

D

Step-by-step explanation:

There is no equation which have no solution.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

1. 1/(x - 31) = 5

1 = 5 · (x - 31)

1 = 5 · x - 155

5 · x = 156

x = 31.2

2. 12 · x - 11 = 0

12 · x = 11

x = 11/12

3. 15 - 3 · x = - 8

3 · x = 23

x = 23/3

4. - x + 91 = 0

x = 91

Answer:

[tex]-27 a^3 b^6 + 8 a^9 b^{12} [/tex]

Step-by-step explanation:

In the picture attached, the problem is shown.

A polynomial in the form x³ + y³ is called a sum of cubes

If we take the expression:

[tex]-27 a^3 b^6 + 8 a^9 b^{12} [/tex]

and take cubic root to each term, we get:

[tex] x = \sqrt[3]{-27 a^3 b^6} [/tex]

[tex] x =\sqrt[3]{-27} \sqrt[3]{a^3} \sqrt[3]{b^6}[/tex]

[tex] x = -3 a b^2[/tex]

[tex]y = \sqrt[3]{8 a^9 b^{12}} [/tex]

[tex] y =\sqrt[3]{8} \sqrt[3]{a^9} \sqrt[3]{b^{12}}[/tex]

[tex] y =2 a^3 b^4[/tex]

The other options are not sum of cubes because 9, -9, b^10 and b^8 are not a perfect cubes.

Answer: 12.6 years

Step-by-step explanation:

Hi, to answer this question we have to apply the compounded interest formula:  

A = P (1 + r/n) nt  

Where:  

A = Future value of investment (principal + interest)  

P = Principal Amount  

r = Nominal Interest Rate (decimal form, 4/100= 0.04)

n= number of compounding periods in each year (1)

t = years

Replacing with the values given  

8200= 5000(1+ 0.04/1)^1(t)

Solving for t

8200 =5000 (1.04)^t

8200/5000 =(1.04)^t

1.64 =(1.04)^t

log 1.64 =log (1.04)^t

log 1.64 = t log (1.04)

log 1.64/ log (1.04) =t

t = 12.6 years

Answer:

6 hours

Step-by-step explanation:

Let's say that the number of hours that Yumi picked litter for is y.

You know that since Yumi picked litter for 2 hours more than Juan, y=x+2.

y=3m

x=2m

Subtract the second equation from the first:

y-x=m

Substitute:

x+2-x=m

2=m

This means that it takes 2 hours per mile of litter. Multiplying this by the 3 miles that Yumi walked makes a total of 6 hours. Hope this helps!

     560 + 140 = 700

I hope this helps <3

Answer:

700 passengers

Step-by-step explanation:

let total be x

560= 4/5 of total

therefore=

equating

560=4/5x

560*5/4=x

700=x

therefore answer is 700 passengers

Answer:

50 songs at $35

Step-by-step explanation:

Answer:

x = 50, y = 35

Step-by-step explanation:

Solve this system of linear equations by using substitution.  Equate the two equations to one another, thus eliminating y:

0.4x + 15 = 0.2x + 25

subtract 0.2x from both sides, obtaining:  0.2x + 15 = 25, or, after combining the constants, 0.2x = 10.

Finally we divide both sides by 0.2, which results in x = 50.

Use the first equation to find y:  y = 0.4(50) + 15 = 20 + 15 = 35

Answer:

1. y+5=4x-40

2.y=4x-45

Step-by-step explanation:

To get the slope of a line you do y₂-y₁/x₂-x₁ so we plug in the values -9+5/9-10 and we get -4

Point-slope form states y-y₁=m(x-x₁) where m is the slope so plug in the values we get y+5=4(x-10) and you get y+5=4x-40 then turn this equation into y=mx+b and get y= 4x-45

Answer:

Step-by-step explanation:

(x +13) + (4x + 2 ) = 180

5x + 15 = 180

Subtract 15 from both sides

5x = 180 - 15

5x = 165

Divide both sides by 5

x = 165/5

x = 33

Check

x + 13 = 33 +13  = 46

And

4x + 2 = 4*33 + 2 = 132 + 2 = 134

Answer:

Bag 1: 20

Bag 2: 40

Step-by-step explanation:

Let x be the amount taken out of bag 2

Then the amount left in each bag can be written as:

Bag 1: 50-3x

Bag 2: 50-x

Since we know that half of bag 2 is bag 1, that gives us:

50-3x = 1/2(50-x)

-> 50-3x = 25-x/2

Now lets isolate x and solve:

25 = 5x/2

-> 50 = 5x

-> x = 10

So plug x bag in for the original equations:

Bag 1: 50-3x = 50-3(10) = 20

Bag 2: 50-x = 50-10 = 40

Answer:

3) The function's leading coefficient is negative.

Explanation:

(1) Is not the answer because when x = 3, f(x) = 0.

(2) Is not the answer because when f(x) = -3,

x = 0.

(4) Is also not the answer because the y-values on both sides of (1, -4) are mirroring each other.

Therefore,

(3) is the answer, by elimination, but also because there is not proof of the leading coefficient being negative, as we don't see the original equation.

Step-by-step explanation:

Use Pythagorean Theorum for this question, a^2+b^2=c^2

If you put the numbers into the equation you get 6.3^2+5.1^2=c^2.

Simplify and get 65.7=c^2

To get rid of the square, you square root both sides, which will get you 8.106=c (since the answer wants round to 3 numbers behind the decimal point)

Therefore the missing length is 8.106cm. (For estimation just write a random number you think it would be before actually solving the problem.
