Answer:

  x = 3

Step-by-step explanation:

The two right triangles share angle A, so the similarity statement can be written ...

  ΔABC ~ ΔADE

Corresponding sides are proportional, so we have ...

  BC/DE = AB/AD

  x/12 = 3/(3+9)

  x = 3 . . . . . . . . . . multiply by 12

Answer:

There is no single answer to this question other than The first graph on the left is the answer. But you should read the explanation and memorize it.

Step-by-step explanation:

It's the first graph on the right. The points are always plotted (without exception) as (x value which means go along the x axis horizontally - left or right.), (y value which means to up (for a plus y) or down for a minus y. These facts are just memorized.

Summary

(x,y)

  • x goes either left or right.
  • x>0 goes right.  
  • x<0 goes left.
  • y goes up or down
  • y > 0 goes up
  • y < 0 goes down

Locations

First point (Please label this as first point)  - 3 (that goes left)  2 that goes up

You should be putting it in the upper left space.

Second Point. (-2,-2) that goes 2 to left and 2 down. You should put that point in the lower left space. There's only 1 point in the lower left space and that is this point.

Third Point (0,1) That's the only point on the y axis. It is above the x axis. It is all by itself on the y axis line. The other two points are done the same way. Please make sure you try them.

The graph of f(x)=3•2^x -3 is shown below. G(x) is a transformation of f(x). How would you write the equation for the function g
Bezzdna [24]

Answer:

C

Step-by-step explanation:

To find the appropriate equation, notice the red graph has shifted up about 6 units. This means that 3*2^x-3 which is shifted by -3 will move 6 up. -3+6= 3. This means the function will have +3. Only B and C are options. Now test a point. Notice the red function crosses the y-axis at about 5 or 6 when x=0.

g(x) = 2^x+3\\g(0) = 2^0+3\\g(0)=1+3\\g(0)=4

This function doesn't match.

f(0) = 3*2^0+3\\f(0) = 3*1+3\\f(0)=6

This function matches. Option C is correct.

What equation is represented by the equation on the graph ?
solmaris [256]

Answer: The correct option is D.

Explanation:

From the graph we noticed that the x intercept of the line is (2,0) and the y-intercept is (0,2).

If the line passing through two points then the equation of line is,

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

Since the ien passing through (2,0) and (0,2).

y-0=\frac{2-0}{0-2}(x-2)

y=-1(x-2)

y=-x+2

This equation is represented by option D, therefore the option D is correct.
