I know the parabola will open downward because the leading coefficient of the equation, being -5, is negative/less than zero.
Answer:
Cohort study
Step-by-step explanation:
The study described above is closely related to a cohort study in that Cohort studies mainly observes the participants who might or might not have been exposed to a particular effect or drug, in this case the oral contraceptive and bacteriuria development. The effect of exposure is observed for a certain period time usually called the follow-up period. Conversely, experimental study will require that participants are divided into groups with one group being exposed to the treatment while the other will be the placebo.This isn't the case in the study described above, hence, it is closely related to a cohort study.
<span>y < x
means
the value of y is less than the value of x
the values in your coordinates are (x,y)
so plug them in
option C is correct
0 < 1</span>
So, givens: total lesson cost of $260, total lessons taken are 6, and the first lesson costs 1.5 (or 3/2) as much as the additional lessons.
First thing to do is to figure out how many additional lessons are in that, which are 5.
Then you can make a 1 variable equation with the information you have. I’m using x as my variable.
260= 3/2x + 5x
Combine like terms.
260 = 13/2x
Divide both sides by 13/2 (treat it as a fraction, and if your calculator cannot make fractions, then decimal might help for this. 13/2=6.5)
X=40
Answer:
6m + 4
Step-by-step explanation:
6 x m + 4 =?
6 x m = 6m
6m + 4 is your end result. It cannot be simplified any more.
