Answer:
x=13
Step-by-step explanation:
3(x-2)-3=30
3x-6-3=30
3x-9=30
3x=30+9
3x=39
x=39/3
x=13
Answer:
The equation has no solution.
Step-by-step explanation:
Hi there!
First, let´s write the equation:
(√x + 3) + 6 = 3
To solve the equation, let´s subtract 6 to both sides of the equation:
√x + 3 = -3
subtract 3 to both sides of the equation:
√x = -6 (the square root of any number can´t be negative, but let´s solve it anyway and then check the solution).
Square both sides of the equation:
x = 36
Now, let´s check the solution:
(√x + 3) + 6 = 3
x = 36
(√36 + 3) + 6 = 3
(6 + 3) + 6 = 3
9 + 6 = 3
15 ≠ 3
Then, the equation has no solution.
Have a nice day!
Answer:
2.5
Step-by-step explanation:
The equation of the line is y=mx+b
so now you can substitute:
3=1/5(-1)+b
3= -1/5+b
now add 1/5 on both sides
3 1/5=b
so the final equation is
y=1/5x+3 1/5
hope this helps!
