Answer:
y + x = 7
Step-by-step explanation:
Standard form should be
y - 9 = -(x+2)
y = -x -2 +9
y + x = 7
Answer:
B
Step-by-step explanation:
The standard form of a circle is
where h and k are the coordinates of the center of the circle and the radius is squared. The radius is easy...take the square root of 25 to get that the radius is 5. Since the pattern for the standard form is "x-" and "y-", if (x+2)^2 is the horizontal placement of the center, it actually was originally written as (x-(-2))^2, so the h coordinate is -2. Same goes for the vertical movement of the center. (y-(5))^2 means that the k coordinate is a positive 5.

Answer:
Step-by-step explanation:
Let us represent:
Banana = b
Tomato = t
Peach = p
Hector can buy a banana and a tomato for 56 cents.
b + t = 56
b = 56 - t
He can buy a peach and a banana for 51 cents
p + b = 51
or
He can buy a tomato and a peach for 69 cents.
t + p = 69
p = 69 - t
p + b = 51
69 - t + b = 51
How much does a banana cost?
