Answer:
Center is at (0,0)
Step-by-step explanation:
An equation of ellipse in standard form is:

Where center is at point (h,k)
From the equation of
. First, we add 45 both sides:

Convert into the standard form with RHS (Right-Hand Side) equal to 1 by dividing both sides by 45:

Therefore, the center of ellipse is at (0,0) since there are no values of h and k.
Answer:
96
Step-by-step explanation:
8z when 12=z
substitute the z for 112 when doing that multiply 8(12)=96
Hello,
y=-k(x+2)(x-1/2)(x-3) where k is a real positive.
We may chose k=1
There are an infinite solutions.
Answer: 
Step-by-step explanation:
Since, the cost of bus fair = x dollars,
Also, a baseball cap which is $18.99 is needed to buy with the given money,
Hence, total expenditure = x + 18.99
While the given money for spending = 24 dollars,
That is, the expenditure can not be exceeded to $ 24.
Thus, the required inequality,

Answer:
You "FOIL" (First, Outer, Inner, Last).

Step-by-step explanation:
You "FOIL" (First, Outer, Inner, Last). Basically, you have to multiple each term by each of the other terms.
(3x+2)(4x-7)
(3x)(4x) + (17)(3x) + (2)(4x) + (2)(-7)
12x^2 - 21x + 8x - 14
12x^2 - 13x - 14
