PPPLLLLEAASEE HEELLPPP!!
Question 2 (Multiple Choice Worth 2 points)

Solve 8x – 2 = 3

x ≈ 2.52

x ≈ 0.26

x ≈ 2.74

x ≈ 0.40




Question 7 (Multiple Choice Worth 2 points)

Solve 5x + 5 = 9x

x ≈ –3.63

x ≈ –0.28

x ≈ 0.07

x ≈ 13.69

Question 8 (Multiple Choice Worth 2 points)

Solve 6x = 24

x ≈ 30.84

x ≈ 1.77

x ≈ 0.56

x ≈ 0.23

Question 11 (Multiple Choice Worth 2 points)

Solve 7.74x + 3 = 10.2

x ≈ –2.15

x ≈ –0.47

x ≈ 0.03

x ≈ 0.28


Question 15 (Multiple Choice Worth 2 points)

Solve 3x

Answer 1

8x-2 = 3
8x-2+2 = 3+2
8x =5
x = 5/8
x=0.625
meaning there's now right answer in your choices, now do the same for the rest

Answer 2

what?

Answer 3

what exactly does the questions ask coz in all of them, the multiple choices are no where near the right answer!!!

Answer 4

thees pics are the questions but pics of the questions! :P

Answer 5

right we dealing with exponents, are you familiar with logs?

Answer 6

Make sure when theres and exponent, put the ^ sign. Your first question should be 8^(x-2)=3.

Answer 7

I'll do the first one then see if you can follow suite:
\[8^{x-2} =3\]
taking log of both sides:
(x-2)log8 = log3
x-2 = log3/log8
x-2 = 0.528
x= 2.528 do you follow? remember the log is to base 10
