I’m pretty sure it is C. h(x)= 3x -10.5
<h3>Answer: 5x-3</h3>
=======================================================
Explanation:
Think of x as a placeholder for a number. For me, I tend to think of it as a box. It's handy that the letter x is part of box, to help make that connection better. We have some box and inside the box goes a number.
If we multiply 5 by whatever is in the box, we can write it like
Then let's say we fill that box with the value 7. We would then have
If we put 3 in the box instead we'll have and so on
Unfortunately the box symbol isn't something we could easily write on a keyboard, so we go with x instead to make life simpler.
--------------------------
So far we've shown that "5 times a number" turns into 5*x or just 5x.
From here we subtract off 3 to get 5x-3 as the final answer. Whatever the result of 5x is, we subtract off 3.
The answer would not be 3-5x since this means "subtract 5x from 3". The order of subtraction matters. In general, A-B is not the same as B-A.
Answer:
Step-by-step explanation:
73/2 : 117/4
=73/2 . 4/117
=146/117
=1.247
Answer:
y^8
Step-by-step explanation:
y^4^2
We know a^b^c = a^(b*c)
y^4^2 = y^(4*2) = y^8
