Answer:
f(5) = 22
f(9) = 34
Step-by-step explanation:
Plug in 5 and 9 separately for the equation of the x values. Multiply them each and add 7 to get these values 22 and 34.
Answer D
...........................................
3.5 pound = 3 5/10 pounds = 3 1/2 pounds
Now, 1 pound = 16 ounces, so 1/2 pound = 16*1/2 = 8 oz
<span>So the answer is 3 pounds and 8 oz.</span>
Answer:
Both are rational.
Step-by-step explanation:
As a rational number can be written in the form p/q where p,q are co-prime integers, let a=p1/q1 b=p2/q2.
And we know the product of two integers is an integer
p1q2, p2q1 are integers. And the sum or difference of two integers is rational, rather being specific, it is an integer.
Thus a+b and a-b is rational.
You have a good response. The only critique I can think of is to reduce the size of that massive decimal number. It doesn't have to be huge as long as it's a random string of digits. For example, e = 2.71828182846... is irrational since it has no pattern in the decimal portion. The decimal portion also goes on forever.
