Answer is B. (−8, −2)

y − x = 6

y + x = −10
...........................add
2y = -4
y = -4/2
y = -2

y − x = 6
-2 - x = 6
-x = 6 + 2
x = 8
x = -8

√(2x+1)<br> Evaluate the integral<br> 2<br> (2x + 1) In (2x + 1)<br> dx.

Crank

Substitute $y=\ln(2x+1)$ and $dy=\frac2{2x+1}\,dx$ , so that

$\displaystyle \int \frac2{(2x+1) \ln(2x+1)} \, dx = \int \frac{dy}y = \ln|y| + C = \boxed{\ln|\ln(2x+1)| + C}$

The price for the items ordered at lunch was $23.45. How much would the price be after tax and tip if the tax rate is 8% and you

kiruha [24]

Cost of items = $23.45

Tax = 8% of $23.45 = 0.08*23.45 = $1.88
Tip = 20% of $23.45 = 0.2*23.45 = $4.69

Total cost = 23.45 + 1.88 + 4.69 = 30.02

Answer: $30.02
