You can "plug in" the value for y from the top eq in the bottom one:

3(-2x+6) - x + 3 = 0

Simplify:

-6x + 18 - x + 3 = 0

-7x + 21 = 0

-7x = -21

x = 3

y = -2*3+6 = 0

To solve a system of inequalities graphically, you just need to graph each inequality and see which points are in the overlap of
Neporo4naja [7]

Consider a system of inequalities

Consider inequality in  two variable

1.  a x + b y ≤ c

2 .  p x + q y ≥ r   3. x ≥ 0  4. y≥ 0

By drawing the graph ,You can find the region bounded by inequality 1, then reason bounded by inequality 2 , and then you can find the region common to both the inequality.

Consider the given  inequality

x + y ≤2

x + y ≥1,

x≥ 0, y≥0.

You can find the solution below.

So, the Statement, To solve a system of inequalities graphically, you just need to graph each inequality and see which points are in the overlap of the graphs is True.

S'y afin buys 12 cookies .He gives 3.1 of the cookies to his mother. He gives 6.1 of the cookies to his brother. a)How many cook
Hunter-Best [27]

Answer:

To represent parts of whole numbers, we use fractions.

So if 4 kids are sharing 3 cookies, what happens?

First, we divide one cookie into four equal parts, and give one part to each kid. Then we do the same with the second cookie, and then with the third one.

In the end, each kid will have three pieces. Each piece is a whole cookie divided into four equal parts.

So we represent this amount as

3 (Number of parts) & 4 (How many equal parts the whole is divided into)

3

4

as a fraction

A fraction is made of two numbers :
