The answer is 13.
To solve this question, you need to determine the slope of the function. if howl is y and the temperature is x of the graph, the slope would be:
9-5/(40-70)= 4/-30= -2/15
Using one of the point and the slope, you can find the number of howl
-2/15= 9-y/40-(-20)
9-y= -2/15 * 60
9-y= -4
y= 9+4= 13

Answer:
$544
Step-by-step explanation:
To determine the original price of the DVD player considering that you know that it had a 75% reduction, you can use a rule of three as the price of $136 represents 25% of the original price and with this you can calculate the price that represents 100%:
$136 → 25%
x ← 100%
x=(136*100)/25=$544
According to this, the answer is that the original price of the DVD player was $544.
64+(2x)=35(x-1)
expand
64+2x=35x-35
minus 2x from both sides
64=33x-35
add 35 to both sides
99=33x
divide both sides by 33
3=x
the number is 3
