Find the number of real number solutions for the equation. x^2+0x-1=0
Kazeer [188]

Answer:

+1

-1

Step-by-step explanation:

Given equation :

x^{2} +0x-1 = 0

x^{2} -1 = 0\\x^{2} =1\\x=\sqrt{1}

x= ±1

x= 1 and x= -1

±1 lies in solution set of real numbers !

The first two steps in determining the solution set of the system of equations, y = x2 – 6x + 12 and y = 2x – 4, algebraically a
Vadim26 [7]
Y = 2x - 4....so sub in 2x - 4 for x in the other equation

y = x^2 - 6x + 12
2x - 4 = x^2 - 6x + 12
x^2 - 6x - 2x + 12 + 4 = 0
x^2 - 8x + 16 = 0
(x - 4)(x - 4) = 0

x - 4 = 0
x = 4

x - 4 = 0
x = 4

solution is (4,4)

A u.s. social security number is a nine-digit number. the first digit(s) may be 0. how many have exactly one didgit equal to 8
strojnjashka [21]
Think of the SS numbers as being a collection of digits.  If any of the digits (say the first one for example) are 8 then all the remaining digits can be anything but 8, meaning there are 9 choices for each remaining digit.  This effectively becomes an 8 digit number with the constraint that there can only be 9 choices for a digit.  This means for the first digit being 8 we have 9⁸ remaining possible numbers. Since we will do this for each of the remaining digits (they each get to be 8 then we count their 9⁸ configurations) we end up with 9(9⁸) or 9⁹≈3.8742E8

Helppppppppppppppppppppp
poizon [28]

Answer:

A

Step-by-step explanation:

Look at both rectangles and list each of the corners coordinates:

The rectangle on the left has coordinates:

R: (-4,-1)

S: (-1,-1)

T: (-1,-3)

U: (-4,-3)

Now because the rectangle transformed to a different location we should take the coordinates of each of its vertices to find what type of transformation this is:

R' : (4,-1)

S' : (1,-1)

T' : (1,-3)

U' : (4,-3)

We can notice that the difference between both sets of points is that the x-value changes sign and the y-values stay the same, therefore the answer is A
