2. a) this is a system of equations. company a = 2.5x + 20 and company b = 4.5x. by graphing it out you will find the intersection which will give you your answer.

b) plug 14 into the two equations. the lower is the one you should go with

Please please help me to simplify this expression from algebra 2 :(?

We Answered:

4+4+3 ?10+3 ?10=
8+6?10

The square root of 90 can also be written as ?9 x 10 or ?9 x ?10. The square root of 9=3, so it is 3 ?10, then you just add it all together. Also you can factor out a two and get 2(4+3?10)

1.
Let log_b.(?68 / 79) = x

b^x = (?68 / 79)

2.
Let log_3.(1/9) = x

3^x = 1/9
log 3^x = log 1/9
x.log 3 = log 1/9
x = log 1/9 / log 3
x = ?2

3.
Log_2.(3x + 5) = 3

2³ = 3x + 5
2x = 2³ ? 5
x = (2³ ? 5) / 2
x = 1.5

4.
logx.0.05 ? ½

Not really an equation here.

5.
9x.e? = 4

ln 9x.e? = ln 4
ln 9x + ln e? = ln 4
ln 9x + 4 = ln 4
ln 9x = ln 4 ? 4
9x = e^(ln 4 ? 4)
x = e^(ln 4 ? 4) / 9
x = 0.00814
