(-0.75, 3.5)
Step-by-step explanation:
See below for graph, please!
Hope this helped!
Brainliest of I helped : )
Here: Remember f(x) is the same thing as y.
Quadratic functions are y=x^2.
So you could literally add anything to it and make it another function. E.g. f(x)=x^2 + 1
You could just keep adding another value to the second term like x^2 + 2.
But if you want functions here you go:
x^2 -3x -4
x^2 +9x +8
x^2
x^2 +1
x^2 -3x -10
x^2 + 2x
2x^2
3x^2
4x^2
How do you graph them? Easy just choose an x value, like 0 or 1 or 7 or -5, and plug it into the equation. If you had f(x)=x^2 then it's just 5^2, 25. So when x is 5, f(x) [y is f(x)] is 25. Likewise you would plug it into 2x^2 and get 2 (5^2). When x is 5, f(x) is 50.... 2(25)= 50
Hello Bubbleshi !
The first step you need to do is get everything in like terms.
- 1/6 and - 7 /4
Look at the denominator (number on the bottom)
6 and 4 go into 12, so lets check that out.
-1/6 , how can we get 12 from the denominator? Multiply it by 2.
So you multiply both the numerator (number on the top) and the denominator.
-1/6 becomes -2/12.
With -7/4, you want to get the 4 as a 12 (like terms!) so once again you multiply it by 3, and multiply the numerator as well.
-7/4 becomes -21/12.
-2/12 + (-21/12) is your final form of the problem.
You add -2 and -21 in the numerator, which is -23.
So its -23/12 which is your final answer.

Answer:
<h2>
64π</h2>
Step-by-step explanation:
A = π r2
diameter : 2 = r
16 : 2 = 8
A = 8²π
A = 64π
Answer:
52.48
Step-by-step explanation:
find the cross sectional area which is the triangle
triangle = 1/2 x 8.2 x 6.4 = 26.24
then, use the area to multiply by the extended length of 2
26.24 x 2 = 52.48
