Answer:
answer = -12
Step-by-step explanation:
substitute y as -3 and z as 4
3(-3) - 2(4) + 5
-9-8+5
-17+5
-12
There are to be exact only 2 ways to answer this equation because of the way math was made.
The correct option is : 2
<u><em>Explanation</em></u>
For finding the mean number of working TV sets, we need to <u>divide the total number of TV sets by the total frequency</u>.
Now for finding the total number of TV sets, first we will <u>multiply each number of TV sets by it's frequency and then sum up all the results</u>.
So, the total number of TV sets

and total frequency 
Thus, the mean number of working TV sets 
95 F = 35 C
5 degrees below 40 degrees Celsius
Answer:
-2
Step-by-step explanation:
Isolate the variable y. Note the equal sign, what you do to one side, you do to the other. Divide 3 from both sides:
(3y)/3 = (15 - 6x)/3
y = (15 - 6x)/3
y = 5 - 2x
Note the equation:
y = mx + b
m = slope
b = y-intercept
x & y = the point (x , y)
Note that the slope is directly next to x. -2 is your answer.
