Answer:

(a)\ (1,5)

Step-by-step explanation:

Given

(x + 9)^2 + (y - 4)^2 = 101

Required

Which of the points does it pass through

To do this, we simply substitute the values of x and y in the above equation.

So, we have:

(a)\ (1,5)

(x + 9)^2 + (y - 4)^2 = 101

(1 + 9)^2 + (5 - 4)^2 = 101

Solve each bracket

10^2 + 1^2 = 101

100 + 1 = 101

101 = 101

The above equation is true,

<em>Hence, it passed through </em>(1,5)

<em>We do not need to check for others</em>

<h3>What is the unitary method?</h3>

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Glurpina is a polymorph alien and can grow extra limbs.

She has 3 hands and can shake everyone's hand at the alien conference in 10 minutes.

She can shake everyone's hand by 3 hands in 10 minutes.

She can shake everyone's hand by 1 hands in 10 / 3 minutes.

She can shake everyone's hand by how many extra hands in 3 minutes.

= 3/ 10 x 3

= 9/10

Thus, She can shake everyone's hand by 9/10 hands in 3 minutes.

NEED HELP! ASAP PLEASE!
Doss [256]

Answer:

(0,-41)

Step-by-step explanation:

You can see that for each 9 units that x goes up, y goes up by 19. If we continue this pattern, it will take 2 more jumps of 9 units for the x value to be 0 or to reach the y intercept. Adding 19 twice to -79 gives -41. Hope this helps!
