Answer:

Javier's equation is not correct because the variable "a" should be multiplied by  only and then added to

Step-by-step explanation:

Let

a------>is the tree’s age in years

we have that

-------> Javier's equation

we know that

The equation that represent the situation is equal to

Solve for a

Multiply by  both sides

Javier's equation is not correct because the variable "a" should be multiplied by  only and then added to

Given:

The degree of polynomial = 9

Leading coefficient is negative.

To find:

The end behavior of the polynomial.

Solution:

Let the polynomial be P(x).

We have,

Degree of polynomial = 9, which is odd.

Leading coefficient is negative.

If the degree of a polynomial is odd and leading coefficient is negative, then

[tex]P(x)\to \infty\text{ as }x\to -\infty[/tex]

[tex]P(x)\to -\infty\text{ as }x\to \infty[/tex]

Therefore, the end behavior of the given polynomial is [tex]P(x)\to \infty\text{ as }x\to -\infty,P(x)\to -\infty\text{ as }x\to \infty[/tex].

Answer:

the third one

Step-by-step explanation:

The inequality says X is less than 1200, this means the arrow needs to be pointing to the left. Because X cannot equal 1200, the circle on 1200 should not be filled in. It is only filled in if it is included.

Answer:

8 hours and 54 minuter

Step-by-step explanation:

1 hour is equal to 60 minutes

we have 8 hours and 0.9 hours

0.9*60=54 minutes

we have 8 hours and 54 minuter

Answer:

The last one

Step-by-step explanation:

First you need to figure out how many minutes are in 0.1 hours

you can do this by dividing 60 minutes by 10

you get 6

multiply 6 and 9 so that you can find out how many minutes 0.9 hours are

this leaves you with 54 minutes

so your answer is 8 hours and 54 minutes

Answer:

interest: $60

Payment: $360

Step-by-step explanation:

I = Prt

Interest for four years = 300 * 0.05 * 4 = 60

P = P₁ + I = 300 + 60 = 360

Final Answer: [tex]3x + 12[/tex]

Steps/Reasons/Explanation:

Question: Simplify the expression [tex]5x + 6(x - 2) - 8(x - 3)[/tex].

Step 1: Expand by distributing terms.

[tex]5x + 6x - 12 - 8(x - 3)[/tex]

Step 2: Expand by distributing terms.

[tex]5x + 6x - 12 - (8x - 24)[/tex]

Step 3: Remove parentheses.

[tex]5x + 6x - 12 - 8x + 24[/tex]

Step 4: Collect like terms.

[tex](5x + 6x - 8x) + (-12 + 24)[/tex]

Step 5: Simplify.

[tex]3x + 12[/tex]

~I hope I helped you :)~

I hate math

First thing's first, PEMDAS. There's nothing to solve in the parenthesis, and there are no exponents, so use multiplication next. 6 • (x-2) and -8 • (x-3)

Your equation after should be

5x + 6x - 12 - 8x + 24

Next would be addition, don't forget it's always left to right.

11x - 12 - 8x + 24

Subtract twelve from the total (or in this case just from 24, and then add the remaining values (that are possible).

11x - 8x + 12

Next, subtract the two remaining x values.

3x + 12

And there you have it. Easy peasy.

If the case is trying to find x, just solve it like this.

3x = -12

x = 4

Answer:

x = 36

Step-by-step explanation:

(3x + 10) + 62 = 180

3x = 180 - 62 - 10 = 108

x = 36

Answer:

Step-by-step explanation:

Answer:

Undetermined x=x

Step-by-step explanation:

First, you need to simplify each side by combining like terms:

(5x - 7x)(+3-4) = (2x - 4x) +1

-2x - 1 = -2x + 1 is your simplified expression.

After adding 1 to both sides, you're left with: -2x = -2x

You can divide both sides by -2, you'd get: x = x

Therefore, it's undetermined. Meaning, there are no possible solutions or there's infinite solutions. In this case, there's infinite solutions.

Answer:

Cassie bought 0.375 pounds of peanuts and 0.250 pounds of cashews, that is, she bought 50% more peanuts than cashews.

Step-by-step explanation:

Since Cassie bought 3/8 of a pound of peanuts and 1/4 of a pound of cashews, to determine the comparison between both nuts the following calculation must be performed:

3/8 = pounds of peanuts

0.375 = pounds of peanuts

1/4 = pounds of cashews

0.250 = pounds of cashews

Therefore, Cassie bought 0.375 pounds of peanuts and 0.250 pounds of cashews, that is, she bought 50% more peanuts than cashews.

Answer:

15

Step-by-step explanation:

First you would replace the x and y's with 1/2 and 3.

So it would look like: (1/2) (3) + 3 1/2 + 20 (1/2)

Next, you go by PEMDAS (parenthesis, exponents, multiplications, division, addition, subtraction)

So you would first multiply and the parenthesis that I added mean multiplication.

1.5 + 3.5 + 10

So then all that is left to do is add because I multiplied everything out.

So it is 5 + 10 which is 15
