In two or more complete sentences, describe how you would draw the graph of the solution set for the following inequality.
2 answers:
Answer:
-To draw the inequality graph, we draw a number line with value ranging from 0 to -4 towards the left side of the line
-Then we draw a line towards the right of the number line starting from -4 digit on the number line. We draw towards the right because the resulting inequality sign is greater than.
Explanations:
Given the inequality function
-3m+18<30
Before we can draw the graph, we need to find the value of m.
First we bring 18 to the other sides
-3m<30-18
-3m < 12
Dividing both sides by -3 we have;
-3m/-3>12/-3 (dividing both sides of an inequality with a negative sign changes the sense of the inequality sign)
m>-4.

Answer:
"To the nearest year, it would be about 9 years"
Step-by-step explanation:
11c)
This is compound growth problem. It goes by the formula:
Where
F is the future amount
P is the present (initial) amount
r is the rate of growth, in decimal
t is the time in years
Given,
P = 20,000
r = 8% = 8/100 = 0.08
F = double of initial amount = 2 * 20,000 = 40,000
We need to find t:
To solve exponentials, we can take Natural Log (Ln) of both sides:
Using the rule shown below we can simplify and solve:
We can write:
To the nearest year, that would be about 9 years
Angles 1, 2, and 3 are all 90°.
10x = 90
.. x = 9
x +y = 90
.. y = 81
5z = 90
.. z = 18
The values of (x, y, z) are (9, 81, 18).
10x = 90
.. x = 9
x +y = 90
.. y = 81
5z = 90
.. z = 18
The values of (x, y, z) are (9, 81, 18).
Answer:
X= 8
Y= 130
(8, 130)

I used a graphing calculator to see where the two equations intersected.
Hope this helped :)
