Solve this equation for x. round your answer to the nearest 0 = ln (x+6)
MissTica

Answer: x=-5

Step-by-step explanation:

To solve this exercise you need to remember the following:

e^{lnx}=e^{lny} → x=y

Therefore, keeping the above on mind, you can solve for x as following:

e^0=e^{ln(x+6)}

e^0=x+6

Remember that, by definition: a^0=1, then you have:

1=x+6

Subtract 6 from both sides of the equation.

Then the value of x is:

1-6=x+6-6\\x=-5

Sara scored 8 goals this season. This is two less than a third of the goals she scored last season.
Charra [1.4K]

Answer:

30 goals last season

Step-by-step explanation:

Goals this season = 8

Goals this season = 1/3 of goals last season - 2

Let Goals scored last season = x

Therefore,

8 = 1/3x - 2

8 = x/3 - 2

8 + 2 = x / 3

10 = x / 3

x = 10 * 3

x = 30

Sara scored 30 goals last season

Evaluate when x = 2<br> -X2 + 5x - 7
Rufina [12.5K]

Answer:

Step-by-step explanation:

f(x)=x²-5x+7

f(2)=2²-5.2+7=4-10+7=11-10=1

f(-1)=(-1)²-5.(-1)+7=1+5+7=13

f(1/3)=(1/3)²-5(1/3)+7=1/9-5/3+7=49/9

∴, f(2)-f(-1)+f(1/3)

=1-13+49/9

=58/9-13

=-59/9
