Determine the solution of the system. show your work Y=5x-9 Y=2x +6

Mathematics
1 answer:
steposvetlana [31]3 years ago

We have 5x-9 = Y= 2x+6
⇒ 5x-9 = 2x+6
⇒ (5x-2x)+ (-9+9) = (2x-2x)+ (6+9)
⇒ 3x= 15
⇒ x=5
Plug x=5 in Y = 5x-9, we have Y= 5*(5)-9
⇒ Y=16
(x,Y)= (5,16)
Hope this would help :))

The simplified form of the function will be (√10 - √10 + √15 - √21 ).

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The expression will be calculated as:-

(√2  + √3 ) ( √5 - √7 ) = √2 (√5 + √7 ) + √3 ( √5 - √7 )

                                    = √2√5 + √2√7 + √3√5 - √3√7

                                    = √10 + √14 + √15 - √21

Therefore simplified form of the function will be (√10 - √10 + √15 - √21 ).

Multiply using partial products
Alex
I don't see what we need to multiply but  here is an example: the numbers of the equation that I'm doing is  12 times 13 and this is how I do it .

  (1)(2)                           Step 1: multiply 3 times 2 then when you get the      
x 1 (3)                             answer you would need to multiply then 2 times 3.
  -------                                     
       (36) ( when multiplying 1 times 3 and then multiply 2 times 3)  
     
       
     Step 3: know that in the third step you would need to multiply 1 times 2 then 1 times 1.

    (1)(2)                                    
  x(1) 3
-------------                                        
       36
   + 120  (when multiplying 1 times 2 then 1 times 1 but I added a zero )
-----------
      156 ( I add them all up and that's the answer )

If need any questions just message me and I will answer back .

Is 12h+6k equivalent to 3(4h+2k)?
meriva

True.

Distribute 3 to all terms within the parenthesis

3(4h + 2k) = 3(4h) + 3(2k) = 12h + 6k

hope this helps

The sum of 3 consecutive odd integers is 19 more than twice the smallest of integers , what are the integers ?
Sedaia [141]

Answer:

13, 15, 17

Step-by-step explanation:

If we let the smallest of these odd integers be "x"

then the next one is "x + 2"

and next one is "x + 4"

We can write an equation from the word problem:

x + x+2 + x + 4 = 2x + 19

let's find x, the smallest, and then find the other 2:

x + x+2 + x + 4 = 2x + 19\\3x+6=2x+19\\x=19-6\\x=13

The next one is 15, and next one is 17

The three consecutive odd integers are 13, 15, 17
