6.3 r < -45.36
Here first we have to solve for r and for that we need to get rid of 6.3 .
To get rid of 6.3, we divide both sides by 6.3 that is
r < -7.2
So the solution is all the values which are less then -7.2
And for graph, we put a blank circle or a parenthesis that is () on -7.2 and extend a line to the left side since the inequality is less then .
Answer:
3
Step-by-step explanation:
Intersections on the x axis occur when y = 0. f(x) is another term for y, so set f(x) equal to zero and solve for the two possible x's.
0 = x^2 - 3x - 40
0 = (x-8)(x+5)
By solving for x, you get 8 and -5. 8 and -5 added together will equal 3.
