Answer:
Step-by-step explanation:
Given
Required
Determine
Open bracket
Equate the equation to 0
Express 3 as 1 + 1 + 1
Collect like terms
Group each terms
Factorize (starting with the first bracket)
Express 0 as 0 + 0 + 0
By comparison
Solving for
Take square root of both sides
Add 1 to both sides
Solving for
Take square root of both sides
Subtract 1 from both sides
Solving for
Take square root of both sides
Subtract 1 from both sides
Substitute the values of a, b and c in
4500 * 0.0725 = 326.25
750 + 326.25 = 1076.25
Hope this helped though I'm not rally sure
27 is the answer to this question
Answer: -72a^3 +108a^2
Collect like terms
(2a)(6a)(2a-8a+9)= (2a)(6a)(-6a+9)=12a^2(-6a+9)
= -72a^3 +108a^2
Your slope would be -1/4x. If you look at the y-intercept on your graph, which is -2, you would start to count up one box and over 4 boxes to the left. We call this rise/run. So knowing what the slope is now, your entire equation would be y= -1/4x - 2. (Also, if the line is going up towards the left it is a negative slope, if it's to the right it is positive.) I hope this helps love! :)
