Answer:
X= 7/5
Step-by-step explanation:
Let's solve your equation step-by-step.
12x−15=6−3x
Step 1: Simplify both sides of the equation.
12x−15=6−3x
12x+−15=6+−3x
12x−15=−3x+6
Step 2: Add 3x to both sides.
12x−15+3x=−3x+6+3x
15x−15=6
Step 3: Add 15 to both sides.
15x−15+15=6+15
15x=21
Step 4: Divide both sides by 15.
15x
/15
=
21
/15
X= 7/5
Answer:
the answer is 12 x 10
Step-by-step explanation:
a method for expressing a given quantity as a number having significant digits necessary for a specified degree of accuracy, multiplied by 10 to the appropriate power, as 1385.62 written as 1.386 × 10^3.
- I’m assuming the expression implies the following:
(1-n)/(n^2 - 1)
The steps goes as follows:
= -(n-1)/(n^2-1) (factored a negative out)
= -(n-1)/[(n+1)(n-1)] (Factored denominator into a difference of squares, but don’t just blindly accept the fact, expand it and you should get the original denominator)
At this point, the (n-1) terms cancel, as you should know: a real number, besides 0, over itself is 1.
= -1/(n+1) , which is the answer
Note: You could also see it as 1/-(n+1) or 1/(-n-1)
Answer:
The radius of the circle is 3 units. TRUE
The center of the circle lies on the x-axis. TRUE
The center of the circle lies on the y-axis. FALSE
The standard form of the equation is (x – 1)² + y² = 3. FALSE
The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9. TRUE
Step-by-step explanation:
x² + y² - 2x - 8 = 0
x² - 2x + y² = 8
Complete the square in x.
x² - 2x + 1 + y² = 9
(x - 1)² + y² = 3²
Center: (1, 0); radius: 3
The radius of the circle is 3 units. TRUE
The center of the circle lies on the x-axis. TRUE
The center of the circle lies on the y-axis. FALSE
The standard form of the equation is (x – 1)² + y² = 3. FALSE
The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9. TRUE
Answer:
1/13
Step-by-step explanation:
Total cards = 52
No: of aces in the cards= 4
Probability = 4/52 = 1/13
I hope im right!!1
