F(x)= 18x^2+15x-10 find x when f(x) =15

Step-by-step explanation:

f(x) is simply another way of saying y

We are told that y = 15, so we set the equation 18x² + 15x - 10 equal to 15.

Add 10

18x² + 15x = 25

18x² + 15x + 25 = 0

Factor

(6x − 5) (3x + 5) = 0

Find both solutions for x

6x - 5 = 0

6x = 5

x = 5/6

Now, for the other solution.

3x + 5 = 0

3x = -5

x = -5/3

3024 rhe base is what up in worry about

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
