Answer:

x² + (y+3)² = 4²

Step-by-step explanation:

A close look at the diagram reveals that the center of this circle is (0, -3) and that the radius is 4 units.

Starting from the general equation of a circle, (x - h)² + (y - k)² = r²

and substituting the givens (h = 0, k = -3, r = 4), we get:

x² + (y+3)² = 4².  This is Answer B.

If you flip two coins 96 times what is the best prediction for the number of times they would both land on tails
emmainna [20.7K]
Flipping two coins gives four possibilities: HH, HT, TH, TT

So P(TT)=1/4

So we'd expect a quarter of the trials to be two tails.

\frac 1 4 \times 96 = 24 trials expected to be two tails.

3 2/3+ 8 7/12<br><br> I need the work
castortr0y [4]

Answer:

\frac{49}{4}

Step-by-step explanation:

Convert each to a improper fraction

3 \frac{2}{3} = \frac{11}{3}

8\frac{7}{12} = \frac{103}{12}

\frac{11}{3} +\frac{103}{12} = \frac{49}{4}

17. Solve the following:<br> x – 3y = 5<br> 5x – 2y = -1
Phantasy [73]

Answer:

(- 1, - 2 )

Step-by-step explanation:

Given the 2 equations

x - 3y = 5 → (1)

5x - 2y = - 1 → (2)

Rearrange (1) expressing x in terms of y by adding 3y to both sides

x = 5 + 3y → (3)

Substitute x = 5 + 3y in (2)

5(5 + 3y) - 2y = - 1 ← distribute left side

25 + 15y - 2y = - 1

25 + 13y = - 1 ( subtract 25 from both sides )

13y = - 26 ( divide both sides by 13 )

y = - 2

Substitute y = - 2 in (3) for corresponding value of x

x = 5 + (3 × - 2) = 5 - 6 = - 1

Solution is (- 1, - 2 )
