20+3x=-25 shown step by step

enot [183]

Question:

20 + 3x = -25

Steps

1. Subtract 20 from both sides

20 - 20 + 3x = -25 - 20

2. Simplify,

3x = -45

3. Divide both sides by 3

3x/3 = -45/3

4. Simplify,

x = -15

Choose the graph that represents the following system of inequalities: y ≥ −3x + 1 y ≤ 1 over 2x + 3 In each graph, the area for

svet-max [94.6K]

Answer:

Correct graph is C

Step-by-step explanation:

Given two inequalities are:

1. $y\leq -3x+1$

2. $y\leq x+3$

Step1 : Remove the inequalities

1. $y=-3x+1$

2. $y=x+3$

Step2 : Finding intersection points of equations

By solving linear equation

$y=-3x+1=x+3$

$-3x+x+3$

$x=-0.5$

Replacing value of x in any equations

we get,

$y=x+3\\$

$y=-0.5+3$

$y=2.5$

Therefore, Point of intersection is (-0.5,2.5)

Step3: Test of origin (0,0)

Here, If inequalities holds true for origin then, shades the graph towards the origin.

For equation 1.

$y\leq -3x+1$

$0\leq -3(0)+1$

$0\leq +1$

True, Shade graph towards origin.

For equation 2.

$y\leq x+3$

$0\leq 0+3$

$0\leq 3$

True, Shade graph towards origin.

Thus, Correct graph is C
