In two or more complete sentences, describe how you would draw the graph of the solution set for the following inequality. -3m+1

Marat540 [252]

First find the value of m by solving the inequality.

Solving the inequality we get value of m: m>-4

Now, for drawing the graph, a dotted line will be on -4, as values greater than -4 are included in the graph. and all the portion on right side of -4 is included in the graph.

Step-by-step explanation:

We need to draw the graph of the solution set for the following inequality. $-3m+18 < 30$

First we will solve the inequality and find value of m

$-3m+18 < 30$

Adding -18 on both sides

$-3m+18-18 < 30-18\\-3m$

Dividing both sides by -3 and reversing the inequality i.e < is changed into >

$\frac{-3m}{-3}-4$

So, value of m is: m>-4

So. for drawing the graph, a dotted line will be on -4, as values greater than -4 are included in the graph. and all the portion on right side of -4 is included in the graph.

The graph is shown in figure attached.

Find the area of the figure

Artyom0805 [142]

Answer:

12 $cm^2$

Step-by-step explanation:

The area of a triangle is $\frac{bh}{2}$ . Here, b = 8, h = 3. So 8*3/2 = 12. The units is $cm^2$ .

So the answer is 12 $cm^2$ .

Anna35 [415]

Answer:

Given,

$\sqrt{ {x}^{2} + 4x + 4} - 3 = 0 \\ = > \sqrt{ {x}^{2} + 4x + 4} = 3 \\ = > {( \sqrt{ {x}^{2} + 4x + 4} })^{2} = {3}^{2} \\ = > {x}^{2} + 4x + 4 = 9 \\ = > {x}^{2} + 4x + 4 - 9 = 0 \\ = > {x}^{2} + 4x - 5 = 0 \\ = > {x}^{2} + 5x - x - 5 = 0 \\ = > x(x + 5) - 1(x + 5) = 0 \\ = > (x - 1)(x + 5) = 0 \\ \\ \sf \: either \: x - 1 = 0 \: \: \: \: \\ = > x = 1 \: \: \\ \\ \sf \: or \\ x + 5 = 0 \\ = > x = - 5 \\ \\ \green{ \boxed{ \bf \: \: \: \: \: x = 1 \: \: or \: - 5}}$

But if we put the value of x = 5 then it doesn’t satisfy the equation.

So,

X = 1
