Equation of circle is x² + y² - 25 = 0

(b).

(-5, 0) » yes

(√7, 1) » no

(-3, √21) » no

(0, 7) » no

Step-by-step explanation:

(a).

If centred at origin, centre is (0, 0)

General equation of circle:

${ \boxed{ \bf{ {x}^{2} + {y}^{2} + 2gx + 2fy + c = 0}}}$

but g and f are 0:

${x}^{2} + {y}^{2} + c = 0 \\ but : \\ c = {g}^{2} + {f}^{2} - {r}^{2} \\ c = { - 25}$

Is the open sentence 8 - 4x = 4x true or false when x=0

kvasek [131]

It is not true because if you add in 0 the equation would be 8-4(0)=4(0)

4x0 = 0

so it would be 8-0=0 which doesn't add up.

What's the answer to number 25?

tatyana61 [14]

Find the difference

5/6-3/4 (you have to get the same denominators by multiply the individual fractions)

(5/6)*2 and (3/4)*3 to get a denominator of 12

10/12-9/12 (subtract numerators, leave denominator)
=1/12 which is the answer

Hope this helps
