Arrange the steps to solve this system of linear equations in the correct sequence.

Mathematics
1 answer:
Gwar [14]3 years ago
7 0

Answer:

x=-3

y=1

Step-by-step explanation:

x+y=-2...(1)

2x-3y=-9...(2)

In equation (1) make x the subject of formula by subtracting y from both sides

x=-2-y...(3)

Substitute (3) into (2)

2(-2-y)-3y=-9

Open the bracket

-4-2y-3y=-9

Collect like terms

-2y-3y=-9+4

-5y=-5

Divide both sides by-5

y=1

Substitute y=1 into(3)

x=-2-1

x=-3

Therefore,x=-3,y=1

Choose the correct description of the graph of the inequality x - 3 >= 5.
lions [1.4K]

The <em><u>correct answer</u></em> is:

D) Closed circle on 8, shading to the right.

Explanation:

First we must solve the inequality:

x - 3 ≥ 5

Add 3 to each side:

x - 3 + 3 ≥ 5 + 3

x ≥ 8

To graph this, we want a circle on 8 Since it is "greater than or equal to," 8 is included in the solution set. This means the circle will be closed.

Since it is "greater than," we want the numbers to the right of 8 on the number line.

This means the inequality will be a closed circle and shaded to the right.

A members-only speaker series allows people to join for $28 and then pay $4 for every event attended. What is the total cost for
wariber [46]

Given:

Joining fee = $28

Fee of each event = $4

To find:

Total cost for someone to attend 4 events.

Solution:

Let the number of events be x and total fee be y.

Fee for 1 event = $4

Fee for x events = $4x

Joining fee remains constant. So, the total fee is

y=28+4x

Substitute x=4 in this equation.

y=28+4(4)

y=28+16

y=44

Therefore, total cost of 4 events is $44.
