PLEASE HELP What is the solution to the sentence ''A number decreased by -5 is at least 7''?

Answers

Answer 1

Answer: so a number degreased by -5 means a number +5 so
x-(-5)
is at least 7
x+5>7
so subtract 5 from both sides
x>2
the solution is any number more than, and including, 2

Answer 2

Answer:

n-5=7

add 5 to both sides

n=12

Is this equation standard form of an ellipse or circle?-3x^2-3y^2-12x-12y+24=0
What's the center?

Answers

The standard form equation for a circle is

$(h-x)^2+(k-y)^2=r^2$

where (h, k) is the center and r is the radius.

The standard form equation for an ellipse is

$((x-h)^2)/(a^2)} + ((y-k)^2)/(b^2) = 1$

(center h, k and major and minor axes a and b)

This equation is standard form for neither, but might be general form for one.
