Answer:

-7.5

Step-by-step explanation:

Whole numbers are natural numbers from 0 to infinity. This does not include decimals or fractions. For example, these numbers are 0, 1, 2, 3, 4...

Integers are whole numbers, but they include negative numbers. So, from negative infinity to positive infinity. This does not include decimals or fractions. For example, these numbers are ... -3, -2, -1, 0, 1, 2, 3 ...

A rational number is any number that can be expressed as a fraction. So, this includes -7.5, as -7.5 can be expressed as - $\frac{15}{2}$ .

Therefore the answer is -7.5.

dexar [7]

You gotta remember that $(f-g)(x)$ means $f(x) - g(x)$ .

So, in this case, f(x) is [4x - 3], g(x) is [x^3 + 2x].
So that : f(x)-g(x) = [4x-3] - [x^3+ 2x] = -x^3 + 4x - 2x - 3 = -x^3 + 2x - 3

Solve for x in the equation C = 8.5x + 6y. Show all work.

8_murik_8 [283]

First we move 6y to the other side. To do this, you subtract 6y on both sides

C - 6y = 8.5x + 6y - 6y

C - 6y = 8.5x

No divide both sides by 8.5 to isolate x

$\frac{C-6y}{8.5} = \frac{8.5}{8.5} x =\frac{C-6y}{8.5} =x$

If AABC ~ ADEF, what is the length of DE?<br><br> NEED HELP ASAP please and thanks In advance

chubhunter [2.5K]

Answer:

DE = 21

Step-by-step explanation:

Recall: the ratio of the corresponding side lengths of similar triangles are equal

Given that ∆ABC ~ ∆DEF, therefore,

AB/DE = BC/EF = AC/DF

AB = 8.4

DE = x

BC = 10

EF = 25

AC = 16.5

DF = 41.25

Let's find DE using AB/DE = BC/EF. Thus:

8.4/x = 10/25

Cross multiply

x*10 = 25*8.4

10x = 210

Divide both sides by 10

x = 210/10

x = 21

DE = x = 21
