Evaluate the integral. (Assume a ≠ b. Remember to use absolute values where appropriate. Use C for the constant of integration.)

Bess [88]

Answer:

F(x)= 5*[ $\frac{x^{3} }{3}$ + (a*b)* $\frac{x^{2} }{2}$ + a*b*x + C.

Step-by-step explanation:

First step we aplicate distributive property to the function.

5*(x+a)*(x+b)= 5*[ $x^{2}$ +x*b+a*x+a*b]

5*[ $x^{2}$ +x*(b+a)+a*b]= f(x), where a, b are constant and a≠b

integrating we find ⇒∫f(x)*dx= F(x) + C, where C= integration´s constant

∫^5*[ $x^{2}$ +x*(a+b)+a*b]*dx, apply integral´s property

5*[∫ $x^{2}$ dx+∫(a*b)*x*dx + ∫a*b*dx], resolving the integrals

5*[ $\frac{x^{3} }{3}$ + (a*b)* $\frac{x^{2} }{2}$ + a*b*x

Finally we can write the function F(x)

F(x)= 5*[ $\frac{x^{3} }{3}$ + (a*b)* $\frac{x^{2} }{2}$ + a*b*x ]+ C.

Fill in the missing numbers to complete the pattern 615,605,595

Sophie [7]

We are given pattern 615,605,595.

Let us check differences of second term - first term and

Third term - second term

Second term - first term = 605 - 615 = -10.

Third term - second term = 595 - 605 = -10.

So, each time 10 is being subtracted from previous term.

So, the sequnace would be

Classify the system of equations and identify the number of solutions.

mestny [16]

Answer:

x = all real numbers

Step-by-step explanation:

first you need to solve the first equation to figure out what y is.

4x - y = 2

add y to both sides of the equation

4x = 2 + y

subtract 2 from both sides of the equation

4x - 2 = y

now that you know what y is, you can substitute it in the next equation.

3y = 12x - 6

3(4x - 2) = 12x - 6

open the parenthesis

12x - 6 = 12x - 6

subtract 12x from both sides of the equation

-6 = -6

regardless of what x is, -6 will always equal -6.

so, the answer is all real numbers.
