Answer:
-b/2a is the equation to find the x coordinate of the vertex point and it's y, when x is plugged into the quadratic equation.
Step-by-step explanation:
Answer:
The answer to your question is diameter = 19.7 in
Step-by-step explanation:
Data
Circumference = 62 in
diameter = ?
Process
1.- Write the formula of Circumference, remember that circumference = perimeter.
Perimeter = 2πr
2.- Equal the equation to the value given
2πr = 62
-Solve it for r
r = 62/2(3.14)
-Result
r = 62/6.28
r = 9.87 in
3.- Find the diameter
diameter = 2r
diameter = 2(9.87)
diameter = 19.7 in
It take 80 cup to fill 5 gallons
3x + 6y = 10 is the equation to determine of an apple x and the price of an orange y
<em><u>Solution:</u></em>
Let the price of each apple = $ x
Let the price of each orange = $ y
Martha bought 3 apples and 6 oranges
She had $10 in her wallet which was enough money for the purchase
Thus the equation is:
Total amount = 3 apples(price of each apple) + 6 oranges(price of each orange)
Thus we get,
![10 = 3x + 6y\\\\3x + 6y = 10](https://tex.z-dn.net/?f=10%20%3D%203x%20%2B%206y%5C%5C%5C%5C3x%20%2B%206y%20%3D%2010)
Thus the equation is found
What can be proven true in the diagram is the statement in letter C. angle CGB is complementary to angle AGD. It is because they both had the same vertex which is point G. Complementary angles are angles which are equal to 90 degrees wherein when you add both angles which are obviously 45 degrees, the sum is 90 degrees.
