Answer:

Step-by-step explanation:

Answer:

This expression is not factorable with rational numbers.

Step-by-step explanation:

The way factoring works, you just want to get it to its smallest form possible. To do that you would divide the entire problem by the Least Common Multiple.

This problem does not have a least common multiple. The LCM of 16 and 64 is 16 but x^2 does not have a number in front. 16k and 64 can be factored but in order to factor the entire problem, x^2 would need to have a number in front that made it divisible by a common multiple of 16 and 64.

Say if the problem was 2x^2+16k+64, you could divide the entire problem by 2. Your answer would be:

It is important to note that when you are factoring, never divide any exponents.

The way to check your work when factoring is to distribute the number outside of the parentheses. So in the example I just gave, you'd multiply everything in the parentheses, except the exponent, by 2. Which will give you the original 2x^2+16k+64.

Whatever number you factor out and end up putting outside your parentheses, should multiply back into the parentheses to give you the original problem. If it doesn't, then the factoring was done incorrectly.

Your answer should include parentheses.

Answer:

x = -5/4

Step-by-step explanation:

3x= 5+7x    (subtract 7x from both sides)

3x - 7x = 5

-4x = 5    (divide both sides by -4)

x = 5/(-4)

x = -5/4

The vertex form of an equation of the parabola with vertex (-1,-3) is:

where a  could be any number, also -2,

Step-by-step explanation:

The vertex form of an equation of the parabola:  

                                                        y = a(x - h)² + k

vertex is (-1, -3)  so  h = -1,  k = -3

so:

   y = a(x - (-1))² + (-3)

   y = a(x + 1)² - 3

Answer:

Trinomial: (2x² – 5x) + (4x – 10)

GCF: x (2x – 5) + 2 (2x – 5)

Step-by-step explanation:

2x² – x – 10

The equation above can be factorised as follow:

2x² – x – 10

Multiply the first term (i.e 2x²) and the last term (i.e –10) together.

2x² × (–10) = –20x²

Find two factors of –20x² such that when we add them together, it will result to the 2nd term in the equation (i.e –x).

The factors are 4x and –5x.

Next, replace –x in the equation above with 4x and –5x. This is illustrated below:

2x² – x – 10

2x² – 5x + 4x – 10

Next, factorise

2x² – 5x + 4x – 10

Trinomial: (2x² – 5x) + (4x – 10)

GCF: x (2x – 5) + 2 (2x – 5)

Step-by-step explanation: grape :3 (hi Kadee)

Answer:

Mai

Step-by-step explanation:

To find the rate, you must determine who is going faster per minute. To do this, you must divide the total number of miles by the total number of minutes.

Mai: 5 miles / 15 minutes = 1/3 miles per minute

Jada: 4 miles / 14 minutes = 2/7 miles per minute

Then, use a common denominator to make calculations easier:

Mai: 1/3 * 7/7

Jada: 2/7 * 3/3

You should get:

Mai: 7/21 miles per minute

Jada: 6/21 miles per minute

By looking at this, you can see that Mai is traveling slightly faster, going more miles than Jada per minute.

The population of town A is 4.5 times greater than the population of town B.

The power of a number describes how many times a number is multiplied by itself.

Given are the population of two towns A and B.

Town A has a population of 1.26×10⁵ and the population of town B is 2.8×10⁴.

To find how many times greater is the population of Town A than the population of Town B we have divide the population of town A by the population of town B which is,

= ( 1.26×10⁵)/(2.8×10⁴) times greater.

= (12.6)/(2.8).                                       ( 10⁵ divided by 10⁴ is 10¹ which is 10)

= 4.5 times greater.

Answer:

y = -5x-19

Step-by-step explanation:

Use the point-slope formula to plug in the x1 and y1 and the slope -5 to get the equation y = -5x-19.

Formula: y-y1 = m(x-x1)

m = slope

x1 = x-value

y1 = y-value

Answer:

y=-5x-15

Step-by-step explanation:

starts off in point-slope form:

y+4=-5(x+3)

distribute the 5:

y+4=-5x-15

subtract 4 from each side:

y=-5x-20

^that answer is in slope intercept form.

Answer:

The decimal point.

Explanation:

in 484.5 the 5 is behind the decimal point. Meaning that it isn't quite a full number.

In 635.82 the 5 is in front of the decimal point. Meaning that this is a whole number.

In digit 484.5, 5 represents the 5 tenth and in digit 635.82, 5 presents 5 ones.

Place value is the estimation of a digit's value based on where it appears in a number

For instance, in digit 27, there are, 2 tens, and 7 ones.

The given digits are 484.5 and 635.82,

In the digit  484.5 the place value of 5 is 0.5 or 5 tenth,

In the digit 635.82 the place value of 5 is 5 or 5 ones.

Therefore, in digit 484.5, 5 represents the 5 tenth and in digit 635.82, 5 presents 5 ones.

Answer:

[tex]c=\frac{82}{3}-\frac{4}{3}d[/tex]

Step-by-step explanation:

1) Set up an equation

Let c be the number of CDs Nakisa bought.

Let d be the number of DVDs Nakisa bought.

[tex]328=12c+16d[/tex]

Explanation: Each CD costs $12 and each DVD costs $16. Nakisa spent $328 altogether, which means $12c+$16d is equal to $328.

The question is asking for the number of CDs that Nakisa bought, so our goal is to isolate c in the equation above.

2) Isolate c

[tex]328=12c+16d[/tex]

Subtract both sides by 16d

[tex]328-16d=12c+16d-16d\\328-16d=12c[/tex]

Divide both sides by 12

[tex]\frac{328-16d}{12}=\frac{12c}{12} \\\frac{82}{3}-\frac{4}{3}d=c[/tex]

[tex]c=\frac{82}{3}-\frac{4}{3}d[/tex]
