Answer:
13.5 hours
Step-by-step explanation:
9hrs= 2 painting
9 divided by 2= 4.5
9+4.5= 13.5
Answer:This is a linear equation.
y = mx+b
y is the total cost.
The slope m is the rate: that's 9 dollars per hour.
x is the number of hours.
b is the initial value: that's 16 dollars.
y = 9x+16
The problem states that the cost was 79 dollars.
Substitute that for y and solve for x.
79 = 9x+16
63 = 9x
x = 7 hour

This is a division problem.
637.2 kg / 9 = 70.8
Answer: 70.8 kg
Answer:
-8,-7,-6,-5
Step-by-step explanation:
to start pick 4 variables lets say x, y, z, and a then remember that consecutive means one after another so x = x ,y = x + 1, z = x + 2, and a = x + 3. x + y + z + a = -26 so x + x + 1 + x + 2 + x + 3 = 26 then solve for x. finally go back and solve for the other variables.
Answer:
y intercept = 3
--- slope
Step-by-step explanation:
Given
The attached graph
Required
Determine the slope and the y intercept
The is at the point where .
From the graph:
Hence,
y intercept = 3
Next, we calculate the slope using:
Where:
So, we have:
