Answer:
6e+52
Step-by-step explanation:
cAlCuLaToR
It should be 620
because the fee is $50, if you subtract that from one hour of work you get 95 that is how much it is per hour. You multiply 95 by 6 to get how much it would cost for the hours of work and then add the $50 back on for the initial fee
We need to check the ordered pairs for x = -2, x=5, x= 2/3 and x = 0.75.
1. For the first function: y = 9-4x
x=-2
The ordered pair is (-2,17).
x = 5
The ordered pair is (5,-11).
x = 2/3
The ordered pair is (2/3, 19/3)
x = 0.75
Answer:
Her mistake was not multiplying both sides of the equation by 0.5
Step-by-step explanation:
The mistake is in Step 1--Tiffany was correct in multiplying the left side (h / 0.5) by 0.5 but made an error on the right side by dividing the 7 by 0.5 instead of multiplying.
<em>Thus, h= 3.5</em>
The zero of a function is the x-value where the function crosses the x-axis. With a graph, it is easier often to just look at where the function crosses the x-axis instead of calculating it mathematically.
