Step-by-step explanation:
Answer:
Smaller x: 1.20
Larger x: 5
Step-by-step explanation:
The zeros of a function h(x) are the values of x for whom h equals zero.
So, in your problem, we have
h (x) = (-4x -5)(-x +5)
h(x) = 0 when either(-4x+5) = 0 or (-x +5) = 0. So, we solve for both cases
Case 1
-4x+5 = 0
-4x = -5 *(-1)
4x = 5
x = 5/4
x = 1.20
Case 2
-x +5 = 0
-x = -5 *(-1)
x = 5
We can usually get a couple of facts for these that let us rule out answers without working out all the details.
The green and red areas are below a CUP parabola, opening up. CUP stands for concave up positive, and tells us there's a positive coefficient on x². Unfortunately all the choices have a positive 1 coefficient, no help here.
Since the areas are below they're going to be y ≤ x² + other stuff. That rules out B and C.
The red and blue parts are below the line, and the line has a positive slope. So that's y ≤ mx + b where m>0 is the positive slope. That rules out D with the negative slope.
Answer: A
Answer:
x= -4
Step-by-step explanation:
3=8x-5(3x+5)
distribute
3=8x-15x-25
combime like factors
28= -7x
divide 28/ -7
x= -4
