Answer:
16
Step-by-step explanation:
Okey dokey my dude, here's the deal. All you have to do to answer this is use order of operations (parentheses exponents multiplication division addition subtraction).
8÷2(<u>2+2</u>)=?
//parenthesis first
8÷2(4)
//Ok here's where people will mess up. They just look at the problem and assume that you should multiply the 2 and (4) first because the 4 is in parenthesis. That's understandable, but wrong. What the equation should really look like is 8÷2·4. So you should do 8÷2 first.
<u>8÷2</u>·4=?
4·4=?
<u>16=16</u>

Y= 3X-9
Step-by-step explanation:
Answer:
2 x² - 6x -5
Step-by-step explanation:
<u><em>Expansion:-</em></u>
Given that the expression
(8x²-7x-2)-(6x²-x+3)
= 8x² - 6x² - 7x +x -2 -3
= 2 x² - 6x -5
<h3>Explain why it is helpful to know the basic function shapes and discuss some ways to remember them. </h3>
- Knowing the basic function shapes and discuss some ways to remember them is helpful because this is useful tools in the creation of mathematical models because we constantly make theories about the relationships between variables in nature and society. Functions in school mathematics are typically defined by an algebraic expression and have numerical inputs and outputs.
Answer:
-3x²-5xeˣ-eˣ
-3eˣx²-11eˣx-6eˣ
Step-by-step explanation:
I'm going to go by the picture and not what you wrote in your title.
To find the derivative of this we have to apply the product rule
(a*b)'=
a'*b+a*b'
We plug in our numbers and get
(-3x²+x-2)'*eˣ+(-3x²+x-2)*eˣ'
Now we can evaluate the derivatives and simplify
(-3x²+x-2)'= -6x+1
eˣ'=eˣ
which means we have
(-6x+1)*eˣ+(-3x²+x-2)*eˣ
Simplify
-6xeˣ+eˣ-3x²eˣ+xeˣ-2eˣ
Combine like terms
-3x²eˣ-5xeˣ-eˣ
Now we just need to find the derivative of this
We can apply the same product rule as we did before
(-3x²eˣ)'
Let's start by factoring out the -3 to get
-3(x²eˣ)'
which is equal to
-3(x²eˣ'+x²'eˣ)
Compute this and get
-3(x²eˣ+2xeˣ)= -3x²eˣ-6xeˣ
Now let's find the derivative of the second part
(-5xeˣ)'
-5(x'eˣ+xeˣ')
-5(eˣ+xeˣ)
-5eˣ-5xeˣ
Which means we have
(-3x²eˣ-6xeˣ)+(-5eˣ-5xeˣ)-eˣ
Combine like terms and get
-3eˣx²-11eˣx-6eˣ
