Please help<br> if x = 3 and y=-4 find x2 + y2 and x2 -y2
lions [1.4K]
1. Plug in the 3 in all the x’s that are in the equation:

(3)2 + y2 = for x2 + y2

(3)2 - y2 = for x2 - y2

This would get you for both equations..

6 + y2 = for x2 + y2

6 - y2 = for x2 - y2

2. Now let’s plug in the value of y which is -4:

6 + (-4)2 = for x2 + y2

6 - (-4)2 = for x2 + y2

This would get you for both equations...

-2 = x2 + y2

14 = x2 - y2


Hope this helped, have an awesome day!

15y-4=12y-28 i dont know what that is so can u give me the answer thank you i really need the answer to this equation​
Andreas93 [3]

Answer:

y=-8

Step-by-step explanation:

Let's solve your equation step-by-step.

15y−4=12y−28

Step 1: Subtract 12y from both sides.

15y−4−12y=12y−28−12y

3y−4=−28

Step 2: Add 4 to both sides.

3y−4+4=−28+4

3y=−24

Step 3: Divide both sides by 3.

3y

3

=

−24

3

y=−8
