Answer:

Whole number= n

n= a²- b²= (a+b)(a-b)

There are infinitely many numbers satisfying this condition. Providing some examples:

a=50, b= 13 ⇒ n= (50+13)(50-13)= 2331
a= 8, b=4 ⇒ n= (8+4)(8-4)= 48
a= 15, b= 12 ⇒ n= (15+12)(15-12)= 81
a= 6, b= 1 ⇒ n= (6+1)(6-1)= 35
a= 70, b= 20 ⇒ n= (70+20)(70-20)= 4500

What is 5/10 + 8/100

Greeley [361]

Answer:

$\frac{29}{50}$

Step-by-step explanation:

We have two fractions and are being asked to add them both.

5/10 and 8/100 don't have the fractions, but 5/10 can be simplified to 1/2, meaning that to make the same denominator, we have to find the half of 100, which would be 50. Now turn the fraction into 50/100.

50/100 + 8/100

58/100

This can be simplifed :

$\frac{58/2}{100/2}$

$\frac{29}{50}$

How would the domain and range of the function<br> 1<br> y = -x-6 be determined? Explain.

FrozenT [24]

Answer:

$- x - 6 = y \\ - x = y + 6 \\ \frac{ - x}{ - 1} = \frac{y + 6}{ - 1} \\ x = \frac{y + 6}{ - 1 } \\ x = - (y + 6)$

I NEED HELP ASAP MARK THEM WITH DOTS!!!

rosijanka [135]

Given data:

$$1 \frac{4}{9} \text { and } 2 \frac{1}{3}$

Plot the points $1 \frac{4}{9} \text { and } 2 \frac{1}{3}$ on the number line.

Let us plot the first point $1\frac{4}{9}$ .

1 unit is completed. So count after 1 (indicated) in the number line.

point after 1 is $1\frac{1}{9}$

point after $1\frac{1}{9}$ is $1\frac{2}{9}$

point after $1\frac{2}{9}$ is $1\frac{3}{9}$

point after $1\frac{3}{9}$ is $1\frac{4}{9}$ .

So, move 4 points after 1 in the number line is $1\frac{4}{9}$ .

Now plot the point $2\frac{1}{3}$ .

To make the denominator 9, multiply and divide numerator and denominator by 3.

$$2 \frac{1}{3}=2 \frac{3}{9}$

2 unit is completed. So count after 2 (indicated) in the number line.

point after 2 is $2\frac{1}{9}$

point after $2\frac{1}{9}$ is $2\frac{2}{9}$

point after $2\frac{2}{9}$ is $2\frac{3}{9}=2\frac{1}{3}$

So, move 3 points after 2 in the number line is $2\frac{1}{9}$ .

The number line is attached below.
