I'm not sure if that's the correct method of finding that (it could be, I was just never shown that kind of method). What I did was multiply everything out, that way you have two numbers vs two equations. Then add those two numbers and turn that into scientific notation.
Answer:
-5.55-4.2c
Step-by-step explanation:
-5.55-8.55c+4.35c
-8.55c and 4.35c are like terms so you have to combine them.
-8.55c+4.35c=-4.2c
-5.55 is NOT a like term so it is on its own.
final answer -> -5.55-4.2c
*** don't forget -5.55 is negitive ***
hope this helped negative:)
This is how to solve the problem: "What is the transformations of f(x)=(x-2)^2-4"
Looking at the quadratic equation given,
f(x) = (x-2)^2 - 4
It's like seeing product of sum and difference of two squares.
(x-2)^2 - 4
[ (x-2) - 2 ] [ (x-2) + 2 ]
[ x - 2 - 2 ] [ x - 2 + 2 ]
[ x - 4 ] [ x ]
[ x^2 - 4x ]
So the final transformation of f(x) = (x-2)^2 -4 is f(x) = (x^2 - 4x).
In this way, we are able to show how a complicated equation to simple yet equal equation in quadratic form.
Answer : 7 pound 4 ounces
1 pound = 16 ounces
x pound = 116 ounces
16x = 116(1) , x= 7.25
116-(7x16) = 4
