Answer:
b=30
Step-by-step explanation:
it hits the y axis at 30.
<span>12x +3y = 12
y = -4x +5
We can convert the first equation to the same form as the second (y=mx+b, or slope-intercept).
12x +3y = 12
3y = -12x +12
y = -4x +4
Comparing the simplified first equation y = -4x +4 to the second equation y = -4x + 5, we see that both have the same slope (m = -4), but different y-intercepts (b = 4, b = 5). This means they are parallel lines, or an inconsistent system. There are no solutions.</span>
The number of units produced by the worker during t hours of work can be modelled by the following function:

To find the number of units produced during first 3 hours, we can substitute 3 for t. This will give us the number of units produced by the worker during first 3 hours.

Thus the worker will produce 67 units during the first 3 hours of the work.
Answer:
trinomial.
Step-by-step explanation:
it has 3 terms. an expression with three terms is a trinomial.
