Answer:
the correct answer is b (4,2)
Answer:
C
Step-by-step explanation:
- Reform the first graph: -3x + 3y = 12; 3y = 12 + 3x; y = 4 + x; y = x + 4
- Compare y = x + 4 and y = x + 4: they are equal, thus the same slope (1) and the same y-intercept (4)
When the leading coefficient is 1,
If the constant ( c term) is a perfect square and the b term is 2* the square root of the c term.
Ex.
x*2 + 10x + 25
2*5 = 10 5*5=25
Ex.
x^2 - 12x + 36
2 * -6 = -12 6*6=36
For #30 I ended up doing a lot of adding & if I’m correct it would take about 3 to 3 & 1/2 years for Marshall & Jim to end up with the same salary. So if I’m correct the equation would be the salary + the raise. So it would be something like s + r =x. X equals the total amount of the salary + the raise put together.
For #32 I wrote it down multiple times to make sure I get it right. I ended coming up with 46<-8x8<-6x. I tried figuring out the answer to that but I didn’t understand so I went on Socratic & it said there was no solution. Yeah
Sorry I couldn’t help with the other 2. I tried my best here.
Answer:
x'-5x=0, or x''-25x=0, or x'''-125x=0
Step-by-step explanation:
The function
is infinitely differentiable, so it satisfies a infinite number of differential equations. The required answer depends on your previous part, so I will describe a general procedure to obtain the equations.
Using rules of differentiation, we obtain that
. Differentiate again to obtain,
. Repeating this process,
.
This can repeated infinitely, so it is possible to obtain a differential equation of order n. The key is to differentiate the required number of times and write the equation in terms of x.
