Mathematics

Y_Kistochka [10]3 years ago
5 0

Answer:

(- 5, 8 )

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x + 5)² + (y - 8)² = 1 ← is in standard form

with centre (h, k ) = (- 5, 8 )

Nia solved the equation -1.98 = 5.2v + 13.1. Her answer was v = -2.9. She is fairly confident about her answer, but wants to do
valina [46]

Answer:

substitute for v, when v = -2.9

Step-by-step explanation:

-1.98=5.2v+13.1

subtract 13.1 on both sides.

-15.08=5.2v

divide by 5.2 to isolate v

\frac{-15.08}{5.2} = \frac{5.2v}{5.2}

-2.9=v

substitute for v

-1.98=5.2(-2.9)+13.1

-1.98=-15.08+13.1

-1.98=-1.98
