Prove: If C⊂A and D⊂B then D−A⊂B−C

nalin [4]

Let $x\in D\setminus A$ , so that $x\in D$ but $x\not\in A$ . Since $D\subset B$ , it follows that $x\in B$ , and since $C\subset A$ , it follows that $x\not\in C$ , which means $x\in B\setminus C$ .

Answer:

- 9 1/4 or the 2 option

Step-by-step explanation:

First, make them into improper fractions.

Next, start subtracting.

Then, you make your answer into a mixed number.

The negative sign should still be in the answer.

Suppose line segment AB has one endpoint at A(0, 0). What are the coordinates of B if (5, 3) is 1/3 of the way from A to B?

Bumek [7]

Given:

Line segment AB has one endpoint at A(0,0).

(5, 3) is 1/3 of the way from A to B.

To find:

The coordinates of point B.

Solution:

Let the coordinates of point B are (a,b).

Suppose point P(5, 3) is 1/3 of the way from A to B.

$\dfrac{AP}{AB}=\dfrac{1}{3}$

$\dfrac{AP}{PB}=\dfrac{AP}{AB-AP}=\dfrac{1}{3-1}=\dfrac{1}{2}$

It means, point P(5, 3) divides the segment AB in 1:2.

Section formula:

If a point divides a line segment in m:n, then

$Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)$

Point P(5, 3) divides the segment AB in 1:2. Using section formula, we get

$P=\left(\dfrac{1(a)+2(0)}{1+2},\dfrac{1(b)+2(0)}{1+2}\right)$

$(5, 3)=\left(\dfrac{a}{3},\dfrac{b}{3}\right)$

On comparing both sides, we get

$\dfrac{a}{3}=5$

$a=15$

$\dfrac{b}{3}=3$

$b=9$

Therefore, the coordinates of point B are (15,9).

Lesson 18: Representing Situations with

Ivenika [448]

Answer:

1. 1.99x ≤ 25

2. 2.49x ≤ 25

3. cx ≤ 25

Step-by-step explanation:

1. The budget of Han to buy Grape is $25.

Now, if he buys x pounds of grapes at the rate of $1.99 per pound, then the inequality that represents the number of pounds of grapes that Han can buy will be given by

1.99x ≤ 25 (Answer)

2. The budget of Han to buy Grape is $25.

Now, if he buys x pounds of grapes at the rate of $2.49 per pound, then the inequality that represents the number of pounds of grapes that Han can buy will be given by

2.49x ≤ 25 (Answer)

3. The budget of Han to buy Grape is $25.

Now, if he buys x pounds of grapes at the rate of $c per pound, then the inequality that represents the number of pounds of grapes that Han can buy will be given by

cx ≤ 25 (Answer)

Write this ratio as a fraction in simplest form without any units. 8 yards to 21 feet

Deffense [45]

8/7. You must turn yards into feet. There are three feet in a yard, so 24 overall. You then divide both 21 and 24 by 3 because it's the smallest common factor.
