Answer:
I will just show you how to substitute.
Step-by-step explanation:
all you have to do is just plug f(x) into the number you want. So if you see any x's, all you gotta do is plug that number after f for x.
So an example of an equation for one of your number is:
you then want to plug the number after f for the x's. (I'm doing f(-3).
You then should get the equation above.
after that you solve.
just follow these steps and you should be fine :))
Answer:
6 less a number y can be represented by the expression 6 - y
You just multiply 1.5x10^3 by 4.3x10^2. 1.5x10^3 is equal to 1500 (move the decimal to the right as many spaces as the exponent gives) and 4.3x10^2 is equal to 430. 1500*430=645000. To get that back down to scientific notation, we would have to move the decimal back to between the 6 and 4 to get 6.45 (Zeros aren't included in scientific notation) We moved the decimal to the left five spaces do the exponent is 10^5. We are left with 6.45x10^5
Let multiply by 35 both sides of the equation
35b+35*3/7=35*2/5
35b+15=14
There are all false
