Answer:
1 solution
no solution
infinitely many
1 solution
Step-by-step explanation:
1. 2.3x-7=-7
2.3x=0
x=0
2. 3x=5+3x
0x=5
x=5/0
That’s undefined
3. 40-4x=4(10-x)
40-4x=40-4x
They both are equal no matter what. So, infinitrly many
4. -7+x=-(x+7)
-7+x=-x-7
2x=0
x=0
1 solution I.e 0
Answer:
(x - 7)² + (y - 4)² = 49
Step-by-step explanation:
Given
Equation: x² + y² = 49
Required:
New Equation when translated 7 units right and 4 units up
Taking it one step at a time.
When the equation is translated 7 units right, this implies a negative unit along the x axis.
The equation becomes
(x - 7)² + y² = 49
When the equation is translated 4 units up, this implies a negative unit along the y axis.
(x - 7)² + (y - 4)² = 49
The expression can be further simplified but it's best left in the form of
(x - 7)² + (y - 4)² = 49
Answer:
x=e^2/5
Step-by-step explanation:
log(20 x) - log(4) = 2
Add log(4) to both sides:
log(20 x) = 2 + log(4)
Cancel logarithms by taking exp of both sides:
20 x = 4 e^2
Divide both sides by 20:
And we get Answer:
x = e^2/5
246 divided by 3 should equal 82
