Solve the simultaneous equations<br> y-2x=6<br> y+2x=0
elena-14-01-66 [18.8K]
Y-2x=6 => y=6+2x
Y+2x=0
(6+2x) + 2x = 0
6 + 4x = 0
4x= 6
X=6/4
X= 3/2
Y=6+2x
Y=6+2. 3/2
Y= 6 + 3
Y=9
Check: y-2x=6
9-2. 3/2 = 6
9 - 3 = 6

2.<br> Which of the functions below is an inverse of the quadratic function f(x) = x2 - 3 ?
mezya [45]

Answer:

the inverse of the quadratic function f(x) = x^2 - 3  is \mathbf{f^{-1}(x)=\pm \sqrt{x+3}}

Step-by-step explanation:

We need to find inverse of the quadratic function f(x) = x^2 - 3

Let

y=x^2-3

Replace x and y

x=y^2-3

Now, we will solve for y

Adding 3 on both sides

x+3=y^2-3+3

x+3=y^2

Taking square root on both sides

\sqrt{y^2}=\sqrt{x+3}\\y=\pm \sqrt{x+3}

Now replace y with f^{-1}(x)

f^{-1}(x)=\pm \sqrt{x+3}

So, the inverse of the quadratic function f(x) = x^2 - 3  is \mathbf{f^{-1}(x)=\pm \sqrt{x+3}}

How many whole numbers are less than 600 but are multiples for both 8 and 11
shutvik [7]

Answer:

6

Step-by-step explanation:

11 = 11*1

8 = 2*4

They have no common factors, so the LCM (least common multiple) is

2*4*11 = 88

The multiples of 8 and 11 below 600 are multiples of 88

88*1 =88

88*2 =176

88*3 =264

88*4 =352

88*5 =440

88*6 =528

This is the last multiple because if we add 88 if would be over 600
