Answer:
y=10x+50
Explanation:
The line starts at point (0,50) which is the y intercept (how much he gets paid to visit house).The line crosses points (10,150) and (20,250) and the slope of these points are 100/10 which when simplified equals 10x which is how much money he gets paid by the hour(x=hours) so y=10x plus the y intercept y=10x+50

Step-by-step explanation:
we know that
The domain of x is equal to the interval--------> ![(-2,3]](https://tex.z-dn.net/?f=%28-2%2C3%5D)

All real numbers greater than

so
The range of the function is the interval--------> ![(-9,16]](https://tex.z-dn.net/?f=%28-9%2C16%5D)
Answer:
x = 5
Step-by-step explanation:
To find the value of x make sure to get it on one side
First subtract 3x from each side. This makes the equation now
3x + 2 = -8 + 25
Now see what 25 subtract by 8 is (17)
3x + 2 = 17
Next subtract 2 from both sides
3x = 15
Lastly, divide 15 by 3, making x equal 5
x = 5
