Answer:
<em><u>D.</u></em>
Step-by-step explanation:
<em>First Quartile = </em><em>52</em>
<em>Second Quartile = </em><em>58</em>
<em>Third Quartile = </em><em>62</em>
f(x) = 250(2^x)
f(12) = 250 (2^12)
Calculate f(12) = 250 (2^12) and you should have the answer. Just remember that f(12) stays the same since it is a function.
Answer:
B
Step-by-step explanation:
Reminder: slope-intercept form is y=mx+b where m is the slope and b is the y intercept
There are two points given on the line: (-1, 2) and (1, -4)
First, find the slope
Reminder: slope is y2-y1/x2-x1
Substituting the numbers into the equation gives -4-(-2)/1-(-1) which would make m=-3
Now that the slope is found, we can use slope point form
Reminder: slope point form is y-y1=m(x-x1)
Substituting the numbers would give this equation:
y-2=-3(x-(-1))
Simplifying the equation would give y=-3x-1.
The slope of the line is 1/4.
Answer: x < 3
<u>Step-by-step explanation:</u>
4(x + 3) < 3(x + 5)
4x + 12 < 3x + 15 <em> Distributed</em>
x + 12 < 15 <em>Subtracted 3x from both sides</em>
x < 3 <em>Subtracted 12 from both sides</em>
