Answer:
(x+2)(3x+1) are the factors
You haven't told me what the question is. But I put the mouse
to my forehead, closed my eyes, took a deep breath, and I could
see it shimmering in my mind's eye. It was quite fuzzy, but I think
the question is
"What score does Andrew need on the next test
in order to raise his average to 72% ?"
The whole experience drew an incredible amount of energy
out of me, and the mouse is a total wreck. So we'll just go ahead
and answer that one. I hope it's the correct question.
The average score on 4 tests is
(1/4) (the sum of all the scores) .
In order for Andrew to have a 72% average on 4 tests,
the sum of the 4 scores must be
(4) x (72%) = 288% .
Out of that total that he needs, he already has
(64% + 69% + 73%) = 206%
on the first three tests.
So in order to average 72% for all 4 tests,
he'll need to score
(288% - 206%) = 82%
on the fourth one.
Answer:
f(-3) = 21
g(3) = 69
Step-by-step explanation:
We have been given the following functions;
f(x) = –6x + 3
g(x) = 3x + 21x–3.
To find f(-3) , we simply substitute x = -3 in the function of f(x);
f(-3) = -6(-3) + 3
= 21
To find g(3) , substitute x = 3 in the function of g(x);
g(3) = 3(3) +21(3) - 3
= 69
Answer:
The correct answer is the equation stands as 4x =40 where x is the number of pages Naomi would require and the value of this x is 10.
Step-by-step explanation:
Number of countries that competed in 1900 summer Olympic games is 28.
Number of countries that competed in 1904 summer Olympic games is 12.
Total number of countries competed in total is 40.
Each page of Naomi's report contains information about 4 of the countries that competed each year.
Let Naomi need x number of pages to incorporate the whole report.
Thus the equation now stands as 4 × x = 40.
⇒ x = 10.
Thus Naomi would require 10 pages to complete her report.
