13.2 first look at the 2 if is lower then the number five so u round down to 0 the decimal stays there so it's no 13.0 now u do the same to the 13 only u round up since its higher so u round it up to 20 and ur answer should be 20.0

When rounding off decimals to the nearest whole number you look for the number to the  right of the decimal point  if it is below 5 take the number that you have before the decimal eg. 13.21543 rounded to the nearest whole number would be 13 if it was 13.91234 the whole number would be   14 because 9 is higher than 5 use 5 as a gauge of what is high and what is low

Answer:

7

Step-by-step explanation:

Subtract 2x from each side

5x + 68 = 103

Subtract 68 from each side

5x = 35

Show whether or not y=x+3 is tangential to the curve y^2=x​
wolverine [178]

The line y = x + 3 has slope 1, so we look for points on the curve where the tangent line, whose slope is dy/dx, is equal to 1.

y² = x

Take the derivative of both sides with respect to x, assuming y = y(x) :

2y dy/dx = 1

dy/dx = 1/(2y)

Solve for y when dy/dx = 1 :

1 = 1/(2y)

2y = 1

y = 1/2

When y = 1/2, we have x = y² = (1/2)² = 1/4. However, for the given line, when y = 1/2, we have x = y - 3 = 1/2 - 3 = -5/2.

This means the line y = x + 3 is not a tangent to the curve y² = x. In fact, the line never even touches y² = x :

x = y²   ⇒   y = y² + 3   ⇒   y² - y + 3 = 0

has no real solution for y.
