What is the slope of y = -x+7?

Answer:

26.85

Step-by-step explanation:

Given:

The equation is

[tex](-a-b)x=3a+3b[/tex]

To find:

The value of x.

Solution:

We have,

[tex](-a-b)x=3a+3b[/tex]

It can be written as

[tex]x=\dfrac{3a+3b}{(-a-b)}[/tex]

[tex]x=\dfrac{3(a+b)}{-(a+b)}[/tex]

Cancel out the common factors.

[tex]x=\dfrac{3}{-1}[/tex]

[tex]x=-3[/tex]

Therefore, the value of x is -3.

Answer: What is a factor?

A factor is a  a divisor of an integer n, also called a factor of n, is an integer m that may be multiplied by some integer to produce n. In this case, one also says that n is a multiple of m. An integer n is divisible by another integer m if m is a divisor of n; this implies dividing n by m leaves no remainder.

Step-by-step explanation: Why can’t certain expressions be factored?

Because there are no common factors other than 1 the constants cannot be factored. And, because there is no x in the second term (10), we cannot factor an x out of the two terms.

I'm not sure if this dividing,multiplying,subtracting or adding but for adding i got 6 as my answer.I don't know if this the correct answer but its better than having no answer right?

Answer:

It depends... look at the bottom of my explanation

Step-by-step explanation:

[tex]5\frac{1}{3}=\frac{31}{3}[/tex]   — I converted this to an improper fraction to make this easier; the 30 added to the 1 in the numerator comes from multiplying 5 by the denominator, 3, to create an equivalent number.

³¹/₃ ÷ ²/₃  — Now we divide the two fractions.

³¹/₃ × ³/₂  — Dividing by one fraction is the same as multiplying by its reciprocal

³¹/₁ × ¹/₂  — One fraction has a 3 in its numerator, the other in its denominator. These two "3" values cancel out

31 ÷ 2  — simplifying the resulting expression

³¹/₂ = 15.5  — two other ways to rewrite it; 15.5 comes from dividing 31 by 2

Now, she can't make part of a batch... could she? If she can, it's 15.5. If she can't, she can make 16 or 15 batches depending on how you round.

That's a judgment call. But I hope you understand this better! Have a great day!

Answer:

After 4 weeks, he will have $57

After 20 weeks, he will have $105

Step-by-step explanation:

6(5v - k) / 2

6(5(5) - 8) / 2

6(17) / 2

102/2 = 51

Answer: below

Step-by-step explanation:

Part A)  After 4 week he will have saved ... (45+3x4= $57)... 57 dollars

Part B) After 20 weeks... (45+3x20= 105)... i dont know if he can buy the skate board bc you never said how much the skateboard cost.

2. 6(5v-k)/ 2

6(25-8)/2

150-48/2

102/2 = 51

Answer:

2 he needs to add 2 to keep the ratio the same, the total would be 12

Step-by-step explanation:

before he adds the book the ratio is 2:1 (fiction to non-fiction) and he add 4 to the fiction so he needs to add 2 non-fiction books because this ration means fiction/2 = non-fiction so 4/2 = 2

Answer:

The answer is 65

Step-by-step explanation:

3-2 = 1

4^3 = 64

64+1 = 65

Hope this helps.

Answer:

[tex]65[/tex]

Step-by-step explanation:

Firstly, you have to Simplify what's inside the parentheses.

and that is 3-2 = 1.

[tex] {4}^{3} + 1[/tex]

Secondly, you have to Simplify 4³ to 64. 4 to the power of 3 is 64.

[tex]64 + 1[/tex]

And lastly, you have to simplify 64 + 1. which is.

[tex]65[/tex]

Therefor, the answer is, 65.

Answer:

y = 4/6x - 4

Step-by-step explanation:

y = mx + b, m = slope and b = y intercept

Rise over run

Rise = +4

Run = +6

This means the slope is 4/6.

The y intercept is at -4.

Now, plug in the numbers for y = mx + b

y = 4/6x - 4

The correct answer is

2 cents.

Answer:

the answer is 0.0800320128 or in simplified form 0.08

Step-by-step explanation:

First you divide 12 ÷ 5.88 = 2.04081632653. Then you divide 20 ÷ 10.20 = 1.96078431373. Lastly you subtract 2.04081632653 - 1.96078431373 =  0.0800320128 or 0.08

Step-by-step explanation:

The value of x from the logarithmic equation is x = 3

The power to which a number must be increased in order to obtain another number is known as the logarithm. A power is the opposite of a logarithm. In other words, if we subtract an exponentiation from a number by taking its logarithm

The properties of Logarithm are :

log A + log B = log AB

log A − log B = log A/B

log Aⁿ = n log A

Given data ,

Let the logarithmic equation be represented as A

Now , the value of A is

log₃ ( x + 12 ) = log₃ ( 5x )

Now , the bases of the logarithm are equal

So , the value of ( x + 12 ) = 5x

On simplifying , we get

x + 12 = 5x

Subtracting x on both sides , we get

4x = 12

Divide by 4 on both sides , we get

x = 3

Therefore , the value of x = 3

Hence , the logarithm equation is solved

2. b. $0.08 per square inch

3. f. $10

4. m. $8

5. h. 79 in²

6. j. 113 in²

Step-by-step explanation:

1. A = πr²

  r = diameter ÷ 2 = 10 ÷ 2 = 5

  A = π(5)² = 25π in² ≈ 78.53981

  $8.00/25π = $0.10 per square inch

2. A = πr²

  r = diameter ÷ 2 = 12 ÷ 2 = 6

  A = π(6)² = 36π in² ≈ 113.0973355

Answer:

440

Step-by-step explanation:

330 divided by 3 times 4 is 440 and thats your answer.

====================================================

Work Shown:

330 pages = 3/4 hour

4*(330 pages) = 4*(3/4 hour)  ........ multiply both sides by 4

1320 pages = 3 hours

1320/3 pages = 3/3 hours ...... divide both sides by 3

440 pages = 1 hour

Ethan's rate is 440 pages per hour.
