Answer:
(x+3)^2+(y−3)^2=9
Step-by-step explanation:
The equation for a circle is given by
(x−h)^2+(y−k)^2=r^2 where (h,k) is the center and r is the radius
(x− -3)^2+(y−3)^2=3^2
(x+3)^2+(y−3)^2=9
Answer:
x = 5/3
Step-by-step explanation:
You ALWAYS want your term to be by itself!! So what you need to do is move your constant away from it.
Step 1: Adjust as needed, subtract 10 from both sides of your equation. It should end up like this.
-3x = 5 - 10
Step 2: Solve as needed before continuing equation.
-3x = -5
Step 3: Now you need to get your term by itself. You should divide -3 on both sides of your equation so you should get something like this.
x = -5 / -3
Step 4: You're basically done now! Just simplify! NEGATIVES CROSS EACH OTHER OUT!!!
x = 5/3 OR 1.6
<em>KEY:</em>
<em>Negative and Negative = Positive</em>
<em>Negative and Positive = Negative</em>
<em>Positive and Positive = Positive</em>
Answer:
A. The variable x in the first equation has a coefficient of one so there will be fewer steps to the solution.
Step-by-step explanation:
Given
Required
Efficient way of solving the equations
<em>The efficient way of solving this problem is by solving for x in the first equation because it has a coefficient of 1;</em>
The evidence is shown as follows;
<em>Make x the subject of formula in equation 1</em>
<em>Substitute 1 + 3y for x in equation 2</em>
<em>Open bracket</em>
<em>Make y the subject of formula</em>
<em>Divide both sides by 23</em>
Recall that x = 1 + 3y
<em>Substitute 0 for y in the above expression</em>
Solving for y in the second equation will take more steps
