5x - 3y = 15
5x - <u>5x</u> -3y = <u>- 5x</u> + 15
<u>-3y</u> = <u>-5x</u> + 15
3y = 5x - 15
divide all of them by 3...
y = 5/3 - 5
The system of equations don't have any solutions due to the exact same x-terms.
For this both system of equations, the answer is A.
The x-terms are the same for the equation to be false.
The constant, however, is indeed different as shown in the equation.
Answer: Set your trinomial equal to 160(360), then solve for "x". I think from your instructions that this is what it is asking you to do. But, there is a simpler way.
Step-by-step explanation:
Answer:
Step-by-step explanation:
a) 8.23 x 10^5 move the decimal over 5 places, 319000000 is 319 million move the decimal over until there is one number on the left side --> 3.19 x 10^8
b) 3.19 x 10^8 / 8.23 x 10^5 = 387.61 roughly 388 times larger
Try this explanation+solution:
1. According to the given graph it is possible to define A - amplitude and B - frequency of this function, then to substitute them to its equation.
2. A=5 (max. and min. values for vertical); B=2 (two periods in the length 2π).
3. answer: y=5sin2x.
