<span>
-3x - 3y = 3

y= 7x +15

replace </span>y= 7x +15 into -3x - 3y = 3
-3x - 3(7x+15) = 3
<span>-3x -21x - 45 = 3
-24x = 48
x = 48/-24
x = -2

</span><span>y= 7x +15
</span><span>y= 7(-2) +15
y = -14 + 15
y = 1

The equation x²– 8x – 5 = 0 can be transformed into the equation (x - p)² = q, where p and q are real numbers. What are the valu
Juliette [100K]

The form (x - p)^2 = q is the form that completing the square will leave us with.

---Add 5 to both sides

x^2 - 8x = 5

---Divide the b term by 2, and square it. Then, add that number to both sides.

-8/2 = -4

(-4)^2 = 16

x^2 - 8x + 16 = 5 + 16

x^2 - 8x + 16 = 21

---Factor!

(x - 4)^2 = 21

p = 4

q = 21

Hope this helps!! :)
