Combine like terms:
3x-2>5x+10 becomes -12 > 2x
Dividing both sides by 2, we obtain x < -6
We know all the side lengths so can use law of cosines. a=90, b=55, and c=50.
2500=8100+3025-2(90)(55)cos(C)
cos(C)=.8712
C=arccos(.8712)=29.4 degrees
There is no x value as there is no solution. I plugged into desmos cause it didnt make sense at first then it showed me that it has no solution.
Step 1: Draw the mapping diagram for the given relation.
Step 2: A relation is a function if each element in the domain is paired with one and only one element in the range.
<span>Step 3: From the mapping diagram, it can be observed that the given relation is not a function as '3' in the domain is paired with two elements - 1 and - 2 in the range and '6' is paired with - 1 and - 2.
Domain Range
3 | -1

6 | -2</span>
Answer:
M = 60
Step-by-step explanation:
First, use the distributive property:
12(m + 15) = 900
12 x m = 12m
12 x 15 = 180
We get the equation 12m + 180 = 900
Subtract 180 from both sides.
12m + 180 - 180 = 900 - 180
We get the equation 12m = 720
Divide by 12 on both sides.
12m/12 = 720/12
We get m = 60
