Equation R: y = -2x + 10
Equation S: y = 3x - 20

What is the solution ( , )

Step-by-step explanation:

3x -20= -2x +10

or,5x=30

or,X=30/5

or,X=6

Y= -2×6 + 10

= -2

therefore solution is (6, -2)

Part 1: x ≥ 17/9

Part 2: x is greater than or equal to seventeen ninths.

Part 3: using x= 3 and 4 respectively, the solution was verified

The complete statement related to this found on (ID: 2020133) is stated below:

Use the inequality to answer Parts 1-3.

-3(x - 2) ≤ one third

Part 1: Solve the inequality. Leave answer in terms of a whole number or reduced improper fraction.

Part 2: Write a verbal statement describing the solution to the inequality.

Part 3: Verify your solution to the inequality using two elements of the solution set.

Use a word processing program or handwrite your responses to Parts 1-3. Turn in all three responses.

Step-by-step explanation:

Part 1) The inequality: -3(x - 2) ≤ one third

-3(x - 2) ≤ ⅓

Multiply through by 3

-3(3)(x-2) ≤ 3(⅓)

-9(x-2) ≤ 1

Expand the bracket

-9x + 18 ≤ 1

Collect like terms

-9x ≤ 1-18

-9x ≤ -17

Divide through by coefficient of x (-9)

-9x/-9 ≤ -17/-9

When you divide an expression in inequality by a negative sign, the inequality sign changes

x ≥ 17/9

Part 2) the verbal statement of the solution:

x is greater than or equal to seventeen ninths.

Part 3) We would verify the solution to the inequality using two elements of the solution set greater than 17/9.

17/9 = 1.89

Let's use x= 3 and x = 4. As they are greater than 17/9

-3(x - 2) ≤ ⅓

When x= 3

-3(3 - 2) ≤ ⅓

-3(1) ≤ ⅓

-3 ≤ ⅓

This satisfies the solution of the inequality

When x= 4

-3(4 - 2) ≤ ⅓

-3(2) ≤ ⅓

-6 ≤ ⅓

This satisfies the solution of the inequality
