x = 2(x+2) + 3(x-1) = 3x + 7
2x + 4 + 3x -3 = 3x + 7
2x + 3x - 3x = 7 - 4 + 3
2x = 6
x = 3
Answer:
Hello,
First equation is false
Second equation is true
Step-by-step explanation:
1)
(4,-3) is a point of the line y=4x-19 since
-3=?4*4-19
-3=-3
2)
(4,-3) is not a point of the line y=1/4x-2 since
-3=? 1/4*4-2
-3=? 1-2
-3≠-1
I have written that because it is difficult for me to understand
"the negative reciprocal of the slope of the first"
the negative reciprocal of 4 should be -1/4.
Equation y=1/4x-2 is false.
The primitive function for
is given by it's indefinite integral.
To calculate it, recall:


Let's begin


To find the costant, we just need to use the fact that 

Therefore,

Answer:
22 peaches
Step-by-step explanation:
I hope this help! :)
I've actually just learned this. We would set up the proportion as X/9=36/X so after we cross multiply we get x^2=324. Then we find the square root of both sides to simplify. And using my calculator the square root of x^2 is just x. And the square root of 324 is 18. So the final answer is x=18 or the geometric mean is 18.
