Question 13-18 & 22-27 will all be answered the same way, so i will walk you through question 13: (6,4) y=3x-2
(x,y)=(6,4)
now that we know the first number in the parenthesis is the x value and the second number in the parenthesis is the y value we can plug it into the equation. (x=6,y=4)
4=3x-2 (add two to each side)
4+2=3x
6=3x (divide 3 from each side)
x=2
---------------
y=3(6)-2
y=18-2
y=16
-------------------
answer: (2,16)
now apply the same principles to the other problems!!! hope this helped!!!
Answer:
The equation has no solution
Step-by-step explanation:
Since the last line of her work resulted in
1 = 2 ← meaningless, then
This indicates the equation has no solution
Answer:
x=ln(41)/ln(243)
Step-by-step explanation:
20(3)^5x=820
3^5x=820/20
3^5x=41
5x=ln(41)/ln(3)
x=(1/5)[ln(41)/ln(3)]
x=ln(41)/ln(3^5)
x=ln(41)/ln(243)
Answer:
8n - (2n + 11 - 54) =
Step-by-step explanation:
6n + 43, I used a calculator !
M=-2/3
This is because it’s the slope I got and I don’t know how to explane it
