33. 15x10=150x9
the answer is b
34. a
#5 is very nicely and correctly done.
#7 says: "No matter what X may be, this function of it is always 9 more than 1/2 of X .".
That's a very powerful statement. Now you know that if X is ever 2, the function will be 1/2(2)+9 which is 10.
If X is ever zero, the function will be 1/2(0)+9 which is 9. If X is ever a cow, the function will be 1/2 of a cow, plus the number 9. Which makes no sense, but that's what the function says.
So, when X is -8, the function is 1/2 of -8, plus 9. Which is 5 ... the 'f' of -8.
Whatever X happens to be at the moment, just write that number in place of X in the function, and it'll show you the function of what X is.
f(a bazillion) = 1/2(a bazillion) + 9 .
f(a-28) = 1/2(a-28) + 9 (but simplify it)
Answer:
After 4 days, the number of people attending both conferences be the same.
Step-by-step explanation:
We are given the following in the question:
Maths conference:
Number of people already signed = 7
Number of people who sign up each day = 2
Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:
History conference:
Number of people already signed =11
Number of people who sign up each day = 1
Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:
Both conference will have same number of people when
Thus, after 4 days, the number of people attending both conferences be the same.
Answer:
$56.70 all together
Step-by-step explanation:
$22.14 for the jeans
$34.56 for the jacket
$56.7 all together
Take your tax and move the decimal over to the left by 2 spaces
8. becomes .08
take .08 and multiply it by the price so
20.50 x .08= 1.64
and
32 x .08=2.56
the number you get is how much the tax is, $1.64 is 8% of $20.15
take that number and add it to your price
$1.64+$20.50= $22.14
