FIND THE VALUE OF X AND Y.(ordered pairs)(x+y,0)=(8,x-y)​

Mathematics
1 answer:
Aliun [14]3 years ago
5 0

Step-by-step explanation:

We know that...

x+y (from the first pair) corresponds to 8(in the second pair)..

0 (from the first pair) corresponds to x-y (in the second pair)..

Hence,

x + y = 8 \\ x - y = 0

By simply adding the two equations we get,

2x = 8 \\ x  = 4

Hence,

By substituting x=4, we get that y=4

Hence,

x=y=4

What is 7/25 in decimal form
timama [110]

Every fraction is just a short way to write a division.
Whenever you see a fraction, it means

            the top number
divided by
            the bottom number.

When you actually do the division, like with a pencil or a calculator,
the quotient you get is the decimal form of the fraction.

I won't insult your intelligence by giving you  7  divided by  25 .
I'm sure you can do that easily.

I also won't insult your intelligence by sending you to a web site.
I assume that if you were on a desert island without your phone
or any 4G coverage, you'd be able to figure out a way to divide
7 by 25.

Write the equation using function notation f(x). then find f(0)<br><br> 2x^2 - 3y = 6
Grace [21]

\quad \huge \quad \quad \boxed{ \tt \:Answer }

\qquad \tt \rightarrow \: f(0) = -2

____________________________________

\large \tt Solution  \: :

\qquad \tt \rightarrow \: 2 {x}^{2}  - 3y = 6

\qquad \tt \rightarrow \: 3y + 6 = 2 {x}^{2}

\qquad \tt \rightarrow \: 3y = 2 {x}^{2}  - 6

\qquad \tt \rightarrow \: y =  \cfrac{2 {x}^{2} - 6 }{3}

\qquad \tt \rightarrow \: y =  \cfrac{2 {}^{} }{3}  {x}^{2}  - 2

[ here, y can be replaced with f(x) because y is a function of x ]

\qquad \tt \rightarrow \: f(x) =  \cfrac{2 {}^{} }{3}  {x}^{2}  - 2

\large\textsf{Find f(0):}

\qquad \tt \rightarrow \: f(0) =  \cfrac{2 {}^{} }{3}  {(0)}^{2}  - 2

\qquad \tt \rightarrow \: f(0) =  0  - 2

\qquad \tt \rightarrow \: f(0) =   - 2
