Which of the following is the graph of:<br>(x-3)^2+(y+1)^2=9?​
Marianna [84]
<h3>Answer: Choice A</h3>

center = (3, -1)

radius = 3

==================================================

Explanation:

Rewrite the y+1 as y-(-1). Rewrite the 9 as 3^2

Then compare to the general form (x-h)^2+(y-k)^2 = r^2

You should find that h = 3, k = -1 and r = 3.

The center is (h, k) = (3,-1) and the radius is r = 3.

Choice A matches with that description.

After working 80 hours at his job, Tyshawn earned a total of $1080. How much does Tyshawn earn
bogdanovich [222]

The amount  Tyshawn earn per hour is $13.5

<h3>Ratio and proportion</h3>

Fractions are written as a ratio of two integers

If after working 80 hours at his job, Tyshawn earned a total of $1080, then;

80 hrs = $1080

In order to calculate the amount earned per hour

Amount per hour = 1080/80

Amount per hour = $13.5

Hence the amount  Tyshawn earn per hour is $13.5

In a certain triangle x,y,z represents side lengths if x=7 and z=5 what must be true about y
irga5000 [103]

Answer:

2 < y < 12

Step-by-step explanation:

Given

x = 7

z = 5

Required

What must be true about y?

To answer this, we first calculate the range as follows;

Minimum = |x - z|

and

Maximum = |x + z|

For Minimum, we have:

Minimum = |7 - 5|

Minimum = |2|

Minimum = 2

For Maximum, we have:

Maximum = |7 + 5|

Maximum = |12|

Maximum = 12

The values of y are then bounded by the following:

Minimum < y < Maximum

This gives

2 < y < 12
