Step-by-step explanation:

This is Finite Math, I got this hehe :)

To find the answer, first you need to understand what R means.

It stands for "row". So R1 means "Row 1".

So: -3R1 + R3 means that you need to multiply -3 by all of the numbers in row 1 and then add all of the numbers in row 3

[0   3   1   -1   l  6]

[0  1   -1   -7  l  0]

[3  0  -2   2   l  12]

[4  1    5   3   l   7]

Then use ^^THAT^^ and apply the next set of instructions.

-4R1 + R4 means that you multiply -4 by all of the numbers in row 1 and then add all of the numbers in row 4:

[4  -11    1   7   l  -17]

[0  1   -1   -7  l  0]

[3  0  -2   2   l  12]

[4   1   5   3   l   7]

Answer:

C

Step-by-step explanation:

The value 500 represent the option C. The amount of money for Julian's initial deposit.

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given that, Julian opened a college savings account.

The amount of money in his account can be calculated using the function,

C(t) = 500 (1.03)^t.

Here t is the time in years since the initial deposit.

When t = 0,

C(0) = 500 (1.03)^0

       = 500 × 1    (since any number x⁰ = 1)

       = 500

So the deposit at t = 0 means the initial deposit.

So 500 is the initial deposit.

Hence 500 represents the initial deposit amount.

If we express  [tex]3x^2-6x-2[/tex] in the form  [tex]a(x-h)^2+k[/tex], then a + h + k = -1

The given quadratic expression is:

[tex]3x^2-6x-2[/tex]

To express [tex]3x^2-6x-2[/tex] in the form [tex]a(x-h)^2+k[/tex], follow the steps below

Rewrite [tex]3x^2-6x-2[/tex] as  [tex]3x^2-6x+3-5[/tex]

Factorize common terms

[tex]3(x^2-2x+1)-5[/tex]

This can be further simplified as:

[tex]3(x-1)^2-5[/tex]

Therefore, the vertex form of the equation  [tex]3x^2-6x-2[/tex] is [tex]3(x-1)^2-5[/tex]

Compare [tex]3(x-1)^2-5[/tex] with  [tex]a(x-h)^2+k[/tex]

a = 3, h = 1, k = -5

a  +  h  +  k  =  3  +  1 - 5

a  +  h  +  k  =  -1

Therefore if we express  [tex]3x^2-6x-2[/tex] in the form  [tex]a(x-h)^2+k[/tex], then a + h + k = -1

Answer:

230/p = 23/100 You would need 1,000 g of snack mix.

Step-by-step explanation:

There are 1000 snack mix would be needed to get 230g of almonds.

Given that;

23% of a snack mix is almonds.

And, there are 230g of almonds.

Let us assume that;

The number of snacks = x

Hence, it can be written as,

23% of x = 230

23/100 × x = 230

23x = 23000

x = 23000/23

x = 1000

Therefore, The number of snacks = 1000 g

Step-by-step explanation:

They all expand back to 16x + 20.

Answer:

8%???????????????????????

I will show you how calculate the Percent Change from 24 to 32.

Basically, we are trying to find the change from 24 to 32 in terms of percent. We do this in three steps:

1) Find the difference between 24 and 32 as a number.

2) Divide the result from Step 1 by the starting number 24.

3) Multiply the result from Step 2 by 100 to get it in terms of percent.

The three steps above can be made into a formula. So, to find the percent change from 24 to 32, we use this formula:

((Y-X)/X)*100 = Percent Change

X is the starting number 24, and Y is the ending number 32 that it changed to. When we enter these numbers into the formula, we get:

((32-24)/24)*100 = 33.33%

So, the answer to the question "What is the Percent Change from 24 to 32?" is:

33.33%

Note: All percent answers are rounded to the nearest two decimals if necessary.

[tex]1x+0.2x\\1.2x[/tex]

You can also work it out by multiplying by 1.2 as stated in answer C. If his haircut costs $10, adding a 20% tip of $2 is the same as multiplying by 1.2.

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

Explanation:

Let's find the LCM of 4 and 5, which are the first two items of the list.

The smallest item in each list is 20, so the LCM of 4 and 5 is 20.

We can replace the "4,5" in the list "4,5,12,15" with "20". So our new list would be "20,12,15".

We then repeat the process of finding the LCM of the first two items

LCM of 20 and 12 is 60.

The list "20,12,15" condenses to "60,15".

Repeat this process of finding the LCM once more and you'll find the overall LCM is 60.

Therefore, the LCM of the entire set {4,5,12,15} is 60. This is the smallest multiple shared by all four values. Interestingly enough, the outer values pair up to multiply to 60, and so do the inner values.

4*15 = 60

5*12 = 60

Answer:

Step-by-step explanation:

when it says altogether most of the time you're supposed to add.

When you add fractions you need to have both denominator (number below the line) be the same. and sense 1/2 and 4/8 are equal we will replace it.

you add the numerators (top numbers) and keep the denominator (bottom number)

[tex]\frac{4}{8} + \frac{5}{8} = \frac{9}{8} =1\frac{1}{8}[/tex]

Sense the numerator is bigger you subtract the bottom number from the top number and put a 1 in front of the fraction.

Answer:

A

Step-by-step explanation:

81 - 1 1/5x [tex]\leq[/tex] 55

Subtract 81 from  both sides

- 1 1/5x [tex]\leq[/tex] -26

Turn - 1 1/5 into the improper fraction -6/5

-6/5x [tex]\leq[/tex] -26

Divide by sides by -6/5 by multiplying by the reciprocal. This also changes the direction of the sign.
