Answer: See explanation
Step-by-step explanation:
Your question isn't complete but let me help out. The equation that will be used to calculate the amount earned for the hours used will be:
= 15 + (5×h)
= 15 + 5h
Let's assume that Sue works for 6 hours, the amount that she'll earn will be:
= 15 + 5h
= 15 + 5(6)
= 15 + 30
= $45
Answer: y=1/3x-2
Step-by-step explanation:
To find the equation of the line, we need the slope and y-intercept. To find the slope, we can take any two points on the graph and use the formula
. To find the y-intercept, we find the point that crosses the y-axis. The two points on the graph are (0,-2) and (3,-1).

Now, we know the slope is 1/3.
The graph crosses the y-axis at (0,-2). Therefore the y-intercept is -2. This tells us that the equation is y=1/3x-2.
Answer:
The point (0,4) doesn't make either equation true.
Step-by-step explanation:
Consider the equations.
and 
We need to determine the point (0,4) make either equation true.
Substitute x=0 and y=4 in
Which is false.
Substitute x=0 and y=4 in 


Which is false.
Hence, the point (0,4) doesn't make either equation true.
f(x) = 3x² + 2
3x² + 2 = 0
3x² = -2
3² + 2 = -2/3
F (-2/3) = 3 (-2/3) cross out the three + 2
= -2 + 2 = 0
Hope this helps a bit...
<span>Given a function, if you suspect a root lies near a specific point on the number line, you can evaluate the function at several nearby values and see whether the evaluation is positive or negative. Using a calculator, you should find two real numbers that are at distance 0.01 from one another, such that one real number evaluates positive, and the other evaluates negative. Then the interval between these values contains a root.</span>
