Solving exponential equation 8^3x+4 = 4^2x-1

Mathematics
1 answer:
Alekssandra [29.7K]3 years ago
4 0

Answer:

x = -14/5

Step-by-step explanation:

Given: 8^(3x+4) = 4^(2x-1)

Rewrite with same base: (2^3)^(3x+4) = (2^2)^(2x-1)

Use exponent rules: 2^(3(3x+4)) = 2^(2(2x-1))

Eliminate bases: 3(3x+4) = 2(2x-1)

9x+12 = 4x-2

5x+12 = -2

5x = -14

x = -14/5

dusya [7]

Answer:

Mean - 5

Median - 5

Mode - 2

Range - 6

Step-by-step explanation:

Mean-

If you add 2 + 7 + 8 + 4 + 8 + 2+ 5+ 5+ 7 +2= 50

50 divided by 10 (the amount of numbers in the equation) = 5 for the mean

Median-

Put the numbers in order which is

2,2,2,4,5,5,7,7,8,8 and the number is the middle is 5

Mode-

The number that repeats the most is 2

Pens are on sale for 3 pens for $6 Karen bought 3 pens Leo bought 1 pen how much more did Karen spend than Leo
Rasek [7]
If the correlation is correct, then 1 pen would be equal to $2. In this case, karen spent $2 for each pen for a total of 3 pens for $6. If Leo bought 1 pen, he would spend $2. So, $6-$2=$4. Karen spent 4 more dollars than Leo. If this helped, please mark me brainliest, thank you and if you need more help, feel free to message me!

(6y+4) = (3y+37) Find the measurement of angle G in the parallelogram EFGH.
IRINA_888 [86]

Yo sup??

The given figure is a parallelogram therefore opposite angles must be equal

6y+4=3y+37

3y=33

y=11

angle H =3*11+37

=70

angle G=180- angle H. (property of parallelogram)

=180-70

=110

Hope this helps
