Question

FAN AND MEDAL AND TESTIMONIAL!!

art A: Explain why the x-coordinates of the points where the graphs of the equations y = 8x and y = 2x + 2 intersect are the solutions of the equation 8x = 2x + 2. (4 points)

Part B Make tables to find the solution to 8x = 2x + 2. Take the integer values of x between -3 and 3. (4 points)

Part C: How can you solve the equation 8x = 2x + 2 graphically? (2 points)

Answer 1

@AlexandervonHumboldt2

Answer 2

all x's are exponents...

Answer 3

is part A because they both are y=something so you can equate them together?

Answer 4

solve equation => y=8x and y=2x +2 which gives x= 1/3...
which satisfies the equation 8x = 2x +2

Answer 5

hence the solution

Answer 6

@camerondoherty @dan815

Answer 7

i think u can make the table urself

Answer 8

dan please say you can help explain part A?

Answer 9

@satellite73

Answer 10

they arent linear they are exponents.

Answer 11

ohk den

Answer 12

no problem process still remains the same

Answer 13

i need part A: not the answer

Answer 14

ohk

Answer 15

@dan815 help me please.

Answer 16

because at that point is where the x,y values of both eqations are the same

Answer 17

so that x value when input into both equations yieds the same y

Answer 18

well idk part a

Answer 19

when u equate the two equations => u get this
8^x = 2^x +2
which is same as the equation that u r given ... that is 8^x = 2^x +2 this.
hence solution of the curve satisfies the equation @knightmare6

Answer 20

DUDE I DONT GET WHAT YOU MEAN I JUST NEED PART A TO CONTINUE

Answer 21

dan. can you please explain

Answer 22

@dan815

Answer 23

that is part A @knightmare6

Answer 24

okay now to part B thanks

Answer 25

that cant be because it says something about the x cordinate.

Answer 26

graph 1 => y = 8^x
graph 2 => y = 2^x +2
plug in different x's between -3 and 3 .... and find different y's corresponding to those x's...
when the y's become equal ...
it will be the required solution .... that x is the solution.

Answer 27

i got part A.

Answer 28

@knightmare6 @ part b

Answer 29

i did part B

Answer 30

okay i finished all of it thanks for trying to help me out i just got confused.

Answer 31

:)
