lana66690 [7]

Answer:

Dr Carter

Step-by-step explanation:

I would want to visit Dr. Carter for an orthodontis appointment for multiple reasons. One, he can prove that he doesn’t do his work sloppily as his office is clean, and two, he can prove that his treatments work. since his teeth are now perfectly straight, that shows that his Braces really work, whereas Dr. Shuman’s treatments either don’t work or take a lot longer for results to appear.

Fine the equation of the line through (o, -3) perpendicular to y =4x+4​
svlad2 [7]

Answer:

The equation of the line is y = -\frac{x}{4} - 3

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

y = mx + b

In which m is the slope and b is the y-intercept(the value of y when x = 0).

Perpendicular lines:

If two lines are perpendicular, the multiplication of their slopes is -1.

Line perpendicular to y = 4x + 4.

This line has slope 4, so our line will have slope:

4m = -1

m = -\frac{1}{4}

So

y = -\frac{x}{4} + b

Through (0, -3)

This means that b = -3

So

y = -\frac{x}{4} - 3
