Write y+1=5/2(x-2)+2 in standard form step by step please

1 answer:

6 0

Answer: 5x - 2y = 8

y+1=5/2(x-2)+2

multiply the each side by 2 to get rid of the fraction

2 (y+1) = (5/2 (x-2) +2 )2

2y+2=5(x-2)+4

now distribute the 5

2y+2=5x-10+4

subtract the two from each side

2y=5x-10+4-2

add like terms

2y=5x-8

subtract 5x from each side

2y-5x=-8

multiple the whole equation by -1 to make the 5x a positive

-2y+5x=8

hope this helps!

Evaluate 5(x + y)2 when x = 3 and y = 9

irakobra [83]

Hey there!

$Answer:\boxed{120}$

$Explanation:$

$5(x+y)2$ when x = 3 and y = 9

Let's first move to x and y.

$x=3\\y=9\\3+9=12$

Now multiply 5 by x and y(3+9).

$5*12(\text{x and y combined)}=60$

Now we have the number 2 left, so we have to multiply 60 by 2.

$60*2=120$

$\boxed{120}\text{ is your final answer.}$

Hope this helps!
