Answer:
x=4
Step-by-step explanation:
tangent lines from the same point to a circle are congruent in length, so we can say that
5x+8 = 8x-4
5x -5x +8 = 8x - 5x -4
8 = 3x - 4
8+4 = 3x -4 + 4
3x = 12
3x/3 = 12/3
x=4
I'm going to rewrite f(x) and g(x) so that I don't get confused.
Based on your description:
f(x) = (2x)
+ x - 1 simplified to 4x
+ x - 1
g(x) = x
+ 3x - 3
Now we handle parts A-D.
A. f(x) + g(x)
We combine like terms.
4x
+ 5x
+ x + 3x - 1 - 3 = 5x
+ 4x - 4
B. f(x) - g(x)
Again combine like terms like normal except this time subtracting.
4x
- x
+ x - 3x - 1 - (- 3) = 3x
- 2x + 2
C. 2f(x) + 2g(x)
Multiply, then again CLT
2f(x) = 8x
+ 2x - 2
2g(x) = 2x
+ 6x - 6
Combine like terms to get 10x
+ 8x - 8
D. 2f(x) - 2g(x)
Use the same 2f(x) and 2g(x) terms and this time just subtract.
You get 6x
- 4x + 4
Answer:
what terms,,?
Step-by-step explanation:
For this case, the first thing we must do is define variables.
We have then:
x: cost of each bag of popcorn
y: cost of each drink
writing the system of equations we have:
9x + 9y = 117
x + 3y = 23
Solving the system of equations we have:
x = 8 $
y = 5 $
Answer:
a system of equations that can be used to find the price of one bag of popcorn and the price of one drink is:
9x + 9y = 117
x + 3y = 23
The price of a bag of popcorn is $ 8.
Yes it is a even number because the numbers that add up may equal the equal number if that answer is correct
