Answer:
x=10
Step-by-step explanation:
Answer: The number of ceral boxes per day.
Because the slope will be [rise of the grah of the model function] / [run of the graph of the model function].
rise = [increase in the number of cereal boxes sold]
run = [days elapsed ]
rise / run = number of cereal boxes sold per day
Answer:
There are 200 students in the seventh grade.
Step-by-step explanation:
For equations like these, you have to use the is/of formula, which is:
Percent/100 = is/of.
Since you are trying to find how many students are in the seventh grade, this means that 52 <u><em>is</em></u> 26% of the total amount of students in the seventh grade. So, the formula would look like so:
26/100 = 52/n.
Next, you have to cross multiply, which means you would multiply 26 by n, and 52 by 100.
Then, you are going to have this left over from the cross multiplying:
5200 = 26n.
Divide 26 on both sides, leaving you with:
1n = 200, or n = 200.
Answer:
8, 10, 3
Step-by-step explanation:
For finding real solutions to cubic equations and those of higher degree, I find a graphing calculator to be useful. The problem can be cast in the form ...
f(x) = 0
where f(x) is the difference between the product of the integers and 240:
f(x) = x(x +2)(x -5) -240
Then all we need to do is ask the calculator to show the x-intercept. It is x=8.
So, the three integers are ...
4 I think is the right answer but I’m not sure so sorry if u get this wrong
