2 negatives can be converted to a plus sign. -(-x) can be +x or just x.
-54--23
-54+23
<u>23-54=-31</u>
78--4
<u>78+4=82</u>
-48/-6
Now let's pause fer a sec. When a negative is being divided by another negative, the quotient(answer to division problem) becomes a positive.
<u>-48/-6=8</u>

<u>50*-4=-200</u>

Answer:
In terms of pi: 164.5pi cm squared
Substituting pi for 3.14: 516.53 cm squared
Step-by-step explanation:
3.5^2 = 12.25pi
12.25*2 = 24.5pi
7pi*20 = 140pi
140 + 24.5 = 164.5pi
164.5*3.14 = 516.53
Answer: 130
Step-by-step explanation: multiply 4 and 28 first because of PEMDAS. After you get 112, add 18 and you get 130.
Given:
The dotted boundary line passes through the points (-3,-8), (1,-2) and (9,10).
Above line is shaded.
To find:
The inequality for the given graph.
Solution:
Consider any two points on the line. Let the two points are (1,-2) and (9,10). So, the equation of the line is:





Multiply both sides by 2.




Above line is shaded and the boundary line is a dotted line. So, the sign of inequality must be >.

This inequality is not in the equations. So, multiply both sides by -1 and change the inequality sign.


Therefore, the correct option is D.
