Solve the equation log4(x + 20) = 3
andre [41]

Answer:

x = 44

Step-by-step explanation:

log4(x + 20) = 3

Raise each side to the power of 4

4^ log4(x + 20) = 4^3

x+20 = 4^3

x+20 = 64

Subtract 20 from each side

x+20-20 = 64-20

x = 44

How many solutions does the system have? y=-5x-1 y=-5x+7
vesna_86 [32]

Answer:

Step-by-step explanation:

to do these types of problems, we must compare the slopes and the y int's

in y = mx + b form, the slope will be in the m position and the y int will be in the b position.

y = mx + b

y = -5x - 1......slope here is -5 and y int is -1

y = -5x + 7....slope here is -5 and y int is 7

learn these....it really helps

if the slopes are the same, but the y int different, there is no solution because ur lines are parallel

if the slopes are different and the y int are different, then there will be one solution

if the slopes are the same and the y int are the same, there is infinite solutions because u have the same line.

so the answer to this problem is : NO SOLUTIONS...ur lines are parallel and never cross
