What is the graph of the inequality 3x+2y>-5

Doss [256]

Answer:

The graph with solution is shown below.

Step-by-step explanation:

We need to find the $x-intercept$ and $y-intercept$ for given equation.

For $x-intercept$ , substitute $y=0$

Considering inequality sign as equality and simplifying,

$3x+2y=-5\\3x+0=-5\\x=-\frac{5}{3}$ , point is $(-\frac{5}{3} ,0)$

Similarly,

For $y-intercept$ , substitute $x=0$

We get,

$3x+2y=-5\\0+2y=-5\\y=-5/2$ , point is $(0,-\frac{5}{2})$

We locate this two points on the graph now and join them.

The joining line will be dotted as the inequality has just 'greater than' symbol. The region above the dotted line is the solution to graph.

The triangle below has a total perimeter of 450 cm:

Korvikt [17]

Equation: 450 = 128 + 150 + n

work:

1st step:
128+150 = 278

2nd step:
450-278 = 172

answer: 172

3rd step (checking) :
450 = 128 + 150 + 172
450 = 278 + 172
450 = 450

Solve the rational equation: x/x+1 = 2/x+1

Tju [1.3M]

Answer:

x = 2

Step-by-step explanation:

$\frac{x}{x+1} =\frac{2}{x+1}$

x ≠ 0

x ≠ - 2

x ≠ - 1

$\frac{x}{x+1}(x+1) =\frac{2}{x+1}(x+1)$

x = 2

What is 3/2m-m=4+1/2m

Annette [7]

Answer:

answer is 08

Step-by-step explanation:

3/2m-m=4+1/2*m

3m/2-m=4+1/2*m

3m/2-m=4+1/2m

3m/2-m=4+1m/2

3m/2-m=4+m/2

2(3m/2-m)=2(4+m/2)

m=m+8
