Answer:
Step-by-step explanation:
PEMDAS
anything done in the parentheses comes first
so you have to add first then multiply
this is not the distributive property unless the two numbers in parentheses are not like terms
A. 2x3=6 and 6x12=72 so 78 is greater than 36
6+72=79 which is less than 90
The general equation given is x^2 - 4x + y^2 = -3. Transform this to an equation of a circle of the form x^2 + y^2 = r^2.
Use completing the square method:
x^2 - 4x + 4 + y^2 = -3 + 4
(x - 2)^2 + y^2 = 1
the center of the circle is (2,0) and r = 1
To check if it intersects the y axis, find the value of the x-intercept.
