Answer:
We need to find a relationship between the equations.
Let's solve for one variable.
2x + 2y = 15
2y = 15 - 2x
We know what 2y is in relation to x. Now we can solve.
2x + 15-2x = 15
15 = 15
Unless there are more equations, this is your answer. For it to be simultaneous you need more than one equation.
Answer:
1) proportional
2) not proportional
3) not proportional
4) have

Answer:
Step-by-step explanation:
2x - 7 + 2x - 5 + 2x - 3 + 2x - 1 + 2x + 3 + 2x + 5 + 2x + 7 Combine like terms
16x / 8 = 48
2x = 48
x = 24
The range is defined as the largest number - the smallest number
The range is between 2x - 7 and 2x + 7
x = 24
The smallest number is 48 - 7 = 41
The largest number is 48 + 7 = 55
The range = 55 - 41 = 14
Why was the 2 in front of the x needed? It was to make sure that I could create an odd number.
Why did I subtract an odd number? That was to make sure that I could create odd numbers.
Why did I start with 2x - 7 and end up 8 terms later at 2x + 7?
So the numbers would cancel and I'd only be left with x's.

Hi there!

To find the indefinite integral, we must integrate by parts.
Let "u" be the expression most easily differentiated, and "dv" the remaining expression. Take the derivative of "u" and the integral of "dv":
u = 4x
du = 4
dv = cos(2 - 3x)
v = 1/3sin(2 - 3x)
Write into the format:
∫udv = uv - ∫vdu
Thus, utilize the solved for expressions above:
4x · (-1/3sin(2 - 3x)) -∫ 4(1/3sin(2 - 3x))dx
Simplify:
-4x/3 sin(2 - 3x) - ∫ 4/3sin(2 - 3x)dx
Integrate the integral:
∫4/3(sin(2 - 3x)dx
u = 2 - 3x
du = -3dx ⇒ -1/3du = dx
-1/3∫ 4/3(sin(2 - 3x)dx ⇒ -4/9cos(2 - 3x) + C
Combine:
