Answer:
- 8
Step-by-step explanation:
Given
3x - 6y = 24 ( divide all terms by - 3 )
x + 2y = - 8
We know that
the equation of a circle is
(x-h)²+(y-k)²=r²
where
(h,k)-----> is the center
r--------> is the radius
is the center is the point (0,0) and radius r=20
then
(h,k) is (0,0)
(x-0)²+(y-0)²=20²---------> (x)²+(y)²=400
the answer is
the option D.) x2 + y2 = 400
Answer: First solve the parentheses using order of operations. Then add and subtract from left to right.
Demo:
(3 * 11) = 33
Equation now looks like:
63 - 21 + 33
63 - 21 = 42
Equation now looks like:
42 + 33
42 + 33 = 75
The value of this expression is 75.
Answer: x=12
Step-by-step explanation:
- Multiply both sides by 27.
- Use this rule: a/b*c=ac/b
- Simplify 4×27 to 108.
- Simplify 108/9 to 12
Hope this helps, HAVE A BLESSED AND WONDERFUL DAY! As well as a great Superbowl Weekend! :-)
