For question 5, the expression would be p - 2. You can read that he is starting with a total of P number of picture frames. If he sells to, you represent this by subtracting 2 from p.

For question 6, the simplified expression is 3x + 19. You will get this by understanding that there are 3 groups of everything in the parentheses. You would read this expression as 4 and 3 groups of 5 and 3 groups of x (4+15+3x). Combine the 4 and 15 to get 19. Rewrite it so the part with the variable is first.

Please see the attached picture.

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.
