Can the equation y=1 be written in the form y=mx+b?

It is technically in the format, it just doesn't have a slope which is why x isn't involved. Otherwise it would look weird to put y=0x+1 even though it would help to comprehend it.

Since y=1 does not have a slope because no x is found, this would be already written in the slope intercept form as y= 0x + 1

This would look like a horizontal line across the y intercept which in this case it would be 1

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

they disappear if your absent from to long. i found out that the hard way.
