Answer:
x = -2
Step-by-step explanation:
-4(x-3) = 20
-4x + 12 = 20
^ Here, Glendon added 12 to 20 instead of subtracting. Her equation was not balanced.
-4x = 8
x = -2
Answer:
It's B
Step-by-step explanation:
Answer:
x^2/100 + y^2/256 = 1
Step-by-step explanation:
The standard form of an ellipse is (x-h)^2/a^2+(y-k)^2/b^2=1
a is the horizontal radius
b is the vertical radius
h is the shift to the right
k is the shift upward
h and k will be shifts left and downward respectively if they are negative. Since the question doesn't mention any shifting we can just let them be 0 so everything is easier. The problem states the vertical axis is 16 and the horizontal axis is 10 so that means a = 10 and b = 16. Now we just plug in.
(x-h)^2/a^2+(y-k)^2/b^2=1
a = 10
b = 16
h = 0
k = 0
x^2/10^2+y^2/16^2=1
x^2/100 + y^2/256 = 1
