Graphing inequalities

1 answer:

8 0

There are three steps:
1.)Rearrange the equation so "y" is on the left and everything else on the right.

2.)Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)

3.)Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).

Iteration - Maths Question attached

Answer:

7.8

Step-by-step explanation:

First I will try 50. I got 127,550, so that was way too big.

Let me try a smaller number. How about 5. I got 155, so that was a bit too small.

Now I'll try 20. I got 8420. Looks like the number is between 5 and 20.

How about 7. I got 399.

Let me try 8. I got 584! That's really close. It's just a little too big.

I tried 7.5, and got 485.624. So close! Just a little higher.

Putting in 7.8 yields 543.192! That's our answer.

How can you solve real-world and mathematical problems with numerical and algebraic equations and inequalities?

Oliga [24]

You can solve real-world and mathematical problems with numerical and algebraic equations and inequalities. Algebra can be applied to the temperature in different places that both change, height of a growing child over time, the speed of a car that changes over time (mph), and the age of people that increases over year. Algebra is used in parts of our everyday life, we just don’t realize it.

Solve each system by elimination. substitution by multiplication

umka2103 [35]

M = 135/19 and n = -5/19

You have to give them like terms so that when you eliminate they cancel out and you can solve. The easiest way to do so is by multiplying the top equation by -4 and the bottom by 3.

Find the value of x in the diagram shown below.

koban [17]

Answer:

a) ∡ADC = 270°

b) ∠DAE = 38°

Step-by-step explanation:

Using Inscribed Angle Theorem :

∡ADC = 2 x ∠ABC
∡ADC = 2 x 135°
∡ADC = 270°

Similarly :

∠DAE = 1/2 x ∡DE
∠DAE = 1/2 x 76°
∠DAE = 38°
