If the graph of f(x) = 9x is shifted 2 units to the right, then what would be the equation of the new graph?
Rudik [331]

Answer:

f(x) = 9x - 18

Step-by-step explanation:

Moving the graph to the left or right involves directly manipulating the "x" value. When you want to shift the graph to the right, you need to subtract the desired value directly from "x". This would make the equation look like this:

f(x) = 9(x - 2)

However, this can be simplified by multiplying 9 by each term in the parentheses.

f(x) = 9x - 18

What is the measure of
Katarina [22]

So for a hexagon, the sum of all interior angles is 720°, all we need to do is add all the angles up and set it to 720 to get angle B.


B+133+102+117+90+170=720


Firstly, combine like terms to get B+612=720


Next, subtract 612 on each side, and your answer should be B=108

Which of the following equations has infinitely many solutions?
Valentin [98]

Answer:

B

Step-by-step explanation:

If you look at A and you subtract 3x by 4x you get x and you subtract 3 from -7 and you get -10. But if you look at B you do the stuff in the parentheses first and you get 4x+12x+28=16x+28 and they're the same so it's B.

What is the approximate positive value of the x-coordinate of the point of intersection of p(x)=5x^2-3 and q(x)=2x+1
Advocard [28]

Hey there! :)

Answer:

x = 1.117

Step-by-step explanation:

Graph the two equations:

p(x) = 5x² - 3

q(x) = 2x + 1

On the graph below, the positive point of intersection is at (1.117, 3.233).

Positive x-value = 1.117.
