Answer:

x=\frac{1}{4}

Step-by-step explanation:

81^{x+1}+3^{4x}=246

81=3^4

Rewrite equation: 3^{4\left(x+1\right)}+3^{4x}=246

3^{4\left(x+1\right)}=3^{4x}\times 3^4

3^{4x}\times 3^4+3^{4x}=246

Factor out 3^{4x}:

3^{4x}\left(3^4+1\right)=246

Divide both sides by (3^4+1):

\frac{3^{4x}\left(3^4+1\right)}{3^4+1}=\frac{246}{3^4+1}

3^{4x}=\frac{246}{3^4+1}

3^{4x}=\frac{246}{82}

3^{4x}=3

Anything to the power of 1 is itself. Hence,

4x=1\\

x=\frac{1}{4}

Help me please ASAP
Lina20 [59]

Answer:

m<2 = 70degrees

m<3 = 70degrees

m<4 = 110degrees

m<5 = 110degrees

m<6 = 70degrees

m<7 = 70degrees

m<8 = 110degrees

Step-by-step explanation:

A line has the angles of 180 degrees so if m<1 is 110 then m<2 must be 70degrees. Then m<4 is opposite side of m<1 so it has to be the same number of degrees and the same for m<3 is the opposite side of m<2.

You repeat the process with 5678

An apartment rents for $800 a month the monthly rent is expected to increase $15 each year what will the rent at the end of the
Nataly [62]
To find this you would do 800 + 15x where x is the amount of years. 

For 9 years it would be 800 + 15(9) which is 800 + 135. 

At the end of 9 years, the apartment's rent would be $935. I hope that's utilities included because... yikes...
