Answer:
the answer is 7!
Step-by-step explanation:
divide 21 and 3 and you get 7
Step-by-step explanation:
5x 3 1/2 = 3 x 5 1/2 is false
The numbers 1, 2, 3, 4, 5, 6, 7 average 4. (have a mean of 4)
Explanation:
1+2+3+4+5+6+7=28
28/7=4
Therefore the numbers have a mean of 4.
Answer:
f(x)=x^2+9x-10
Step-by-step explanation:
<u>Standard Form of Quadratic Function</u>
The standard form of a quadratic function is:

where a,b, and c are constants.
The factored form of a quadratic equation is:

Where
and
are the roots or zeros of f, and a is constant.
We know the zeros of the function are 1 and -10. The function is:


Operating:

Joining like terms:

Since we are not given any more restrictions, we can choose the value of a=1, thus. the required function is:
