Write an inequality for the given graph.
Gekata [30.6K]

Answer:

y

Step-by-step explanation:

<em>Find the equation of the dashed line</em>

The line pass through the points

A(0,-3) -----> is the y-intercept of the line

B(6,0)

Find the slope of the line m

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{0+3}{6-0}=0.5

Remember that

The equation of the line into slope intercept form is equal to

y=mx+b

we have

m=0.5

b=-3  

substitute

y=0.5x-3

<em>Find the inequality</em>

we know that

The solution of the inequality is the shaded area below the dashed line

so

y

This system of equations has an infinite number of solutions. Define the solutions algebraically, and allow z to represent all r
Soloha48 [4]

Answer:

x = 12z + 1  and y = 10z - 1

Step-by-step explanation:

To solve the system of equations, we can use the substitution method

If we call

3x - 4y + 4z = 7 I

x - y - 2z = 2 II

2x - 3y + 6z = 5 III

Clearing II  x = 2 + y + 2z

Now, replacing II in III

2(2 + y + 2z) - 3y +6z = 5

4 + 2y + 4z - 3y + 6z = 5

10z - y = 1 from here y = 10z - 1

Finally, replacing y in I

3x - 4(10z - 1) + 4z = 7

3x -40z + 4 + 4z = 7

3x - 36z = 3

3x = 36z + 3

x = 12z + 1

Done
