Answer: x=4
Explanation:
To find the x-intercepts of a function, you set the function equal to zero and then solve for the values of x that make the function equal to zero.
The function given is:
f(x) = -2x - 3x + 20
To find the x-intercepts, we set f(x) equal to zero:
0 = -2x - 3x + 20
Now, combine the x terms:
0 = -5x + 20
Next, isolate the x term:
5x = 20
Finally, solve for x by dividing both sides by 5:
x = 20 / 5
x = 4
So, the x-intercept of the function f(x) = -2x - 3x + 20 is x = 4.
