Answer:

Step-by-step explanation:

y = x^2 - 2x + 2

y = (x - 1)^2 - 1 + 2

y = (x - 1)^2 + 1

Calculate the slope between the points: (4, -9) and (5, 1)
12345 [234]

Answer:

The answer is A- m=10

Step-by-step explanation:

The way to find slope is known as "Rise over Run" meaning the increase of Y over the increase of X. The increase of Y is 10 because 1 - (-9) = 10. The increase of X is 1 because 5 - 4  = 1. 10 over 1, or 10 / 1, equals 10.

A combination lock has numbers 0-49 on it. How many different 3-digit lock
Harman [31]

Answer:

19,600

Step-by-step explanation:

0-49=50 numbers

n=50

r=3

C(n,r)=n!/(r!(n-r)!)

=50!/(47!)(3!)

C(n,r)=C(50,3)

=50!/(3!(50−3)!)

= 19600

Complete the solution of the equation. find the value of y when equals 2. -3x-8y=10
Afina-wow [57]
The value of y can be calculated by translating the equation such that we solve y in terms of x.

                            -3x - 8y = 10
 
                               -8y = 10 + 3x
 
                               y = (10 + 3x) / -8

Then, we substitute 2 to the x in the equation.

                             y = (10 + 3(2)) / - 8  = 16/-8

                                y = -2 

Thus, the value of y in the equation is -2.
