Answer:
x = 21
Step-by-step explanation:
3x + 18 + 4x + 15 = 180
7x + 33 = 180
7x = 147
x = 21
Amplitude is equal to 2 and the maximum output is 2 for t=pi/2+2kpi. k is an integer value.
Solve for x: 2x - y = 3 x + y = 3?
? can someone explain this for me plz

Hi,
For this question, we are given the following system of equations:
2x - y = 3
x + y = 3
Let's make the first equation in the form of y = mx + b as shown below:
y = 2x - 3
x + y = 3
Now, substitute the first equation into the second to get:
x + 2x - 3 = 3
Combine similar terms to get:
3x = 6
x = 2
We now know that x = 2 and can plug this value into one of the given equations to get:
2 + y = 3
y = 1
FINAL ANSWER: x = 2 ; y = 1
I hope that helps you out!

Answer:
Diverges; no sum
Step-by-step explanation:
This is comparable to:
where:
r is the common ratio and
is the first term.
The series converges to:
![\text{First term}\cdot \frac{1}{1-\text{common ratio}}](https://tex.z-dn.net/?f=%5Ctext%7BFirst%20term%7D%5Ccdot%20%5Cfrac%7B1%7D%7B1-%5Ctext%7Bcommon%20ratio%7D%7D)
if the ratio's absolute value is less than 1.
This is a geometric series.
The common ration is -1.04 .
The first term in the series is 0.001.
Since the absolute value of -1.04 is 1.04>1, the series diverges.
