ANSWER
The correct answer is B
<u>EXPLANATION</u>
The first function is
We make y the subject to obtain;
Let us quickly write this in the vertex form.
Since the 
is negative, the graph opens up.
The vertex is at 
The y-intercept is 
The x-intercept is found by equating the function to zero.
With these information we can quickly sketch the graph as shown in the attachment(the red graph).
For the second function,
we again make y the subject to obtain,
This is a basic quadratic function that can be graphed easily. Note that it is also a maximum graph.
From the graph the solution to the two functions is
Answer:
26.3 hours
Step-by-step explanation:
We need to divide 250 by 9.50, therefore we get the answer ≈ 26.3
For this question, set up an equation. 60 times what decimal is 27?
60x=60
x=0.45
Convert this decimal to a percentage by multiplying it by 100:
45%
For this question, set up an equation. 55% (or 0.55) times what number equals 22?
0.55x=22
<em>*Divide both sides by 0.55*</em>
x=40
Hope this helps!!
Answer:
It would be x < 4.
Step-by-step explanation:
Your answer would be x < 4. This is because with this inequality, x would always be less than 4.
Know This:
<em>If it was less than or equal to 4 feet, it would of been x ≤ 4.</em>
Tips:
<em>Less or equal to: x ≤ 4</em>
<em>Less than: x < 4</em>
<em>More or equal to: x ≥ 4</em>
<em>More than: x > 4</em>
