Help me with both questions <br>plz read carefully so you can help me

Scrat [10]

Answer:

2. Both

3. e = 3, f = -5, g = 2

Step-by-step explanation:

2. Order doesn't affect product

3. You get e • f = -15, e • g = 6, f • g = -10 from the problem.

e = -15/f (solve for e)

(-15/f) • g = 6 (plug into second equation)

(-15g/f) = 6 (multiply)

-15g = 6f (multiply)

(-5g/2) = f (divide)

(-5g/2) • g = -10 (plug into last equation)

(-5g^2)/2 = -10 (multiply)

-5g^2 = -20 (mulitply)

g^2 = 4 (divide)

g = 2 (square root)

e • g = 6 (plug in for g, solve for e)

e • 2 = 6

e = 3

f • g = -10 (plug in for g, solve for f)

f • 2 = -10

f = -5

I don't know if your teacher made a typo because I tried this multiple times and got the same answer. I don't know how e is negative.

Evaluate this integral. I'm not sure how to evaluate integrals with absolute values.

SOVA2 [1]

Answer:

Step-by-step explanation:

The first step is to understand what the integrand looks like. (See the graph below.)

It is -1 for x < 0 and +1 for x > 0. Thus, the value of this integral is ...

$\int\limits^0_{-1} {-1} \, dx + \int\limits^2_0 {1} \, dx=-1+2=1$

_____

Essentially, you treat the absolute value as a piecewise linear function. This is the same way you treat an absolute value in any equation or inequality.

Here, this means you divide the integral into two parts: one where the integrand is -x/x, and one where it is +x/x.
