How do i solve this problem? how did they get 2.5?
WARRIOR [948]
Take the GCF (-8t) of the given expression.

You'll get -8t(2t-5).

Now, set each equal to zero and solve for x.

-8t = 0 2t-5=0

t=0 t = 5/2 (Or 2.5 seconds)

Shawna, Dexter, and Tilana are solving the equation -2.5(5-n)+2=15. Shawna says, “I can begin by dividing each side of the equat
laila [671]
Hi!
Shawna is correct because since it's multiplied to the  5-n you have to do the opposite which is division. 
Dexter is also correct because after distributing you can continue solving, there is nothing wrong with that. 
Hope this helps!

Which graph represents the polynomial function g(x)=x3+x2−17x+15?
IrinaVladis [17]

The graph which represents the polynomial function g(x) is:

the 2nd graph in the second line

Step-by-step explanation:

g(x) = x³ + x² - 17x + 15 is a cubic function because the greatest power

of x is 3

All graphs represent cubic functions

So to find which graph which represents g(x) we will do these steps

1. Put x = 0 to find the y-intercept

2. If there are more than one graph have the same y-intercept we will

   find the maximum and the minimum points of the cure

3. If you still don't know which graph find the x-intercepts

Now let us find the graph which represents g(x)

∵ g(x) = x³ + x² - 17x + 15

∵ x = 0

∴ g(0) = (0)³ + (0)² - 17(0) + 15

∴ g(0) = 15

∵ g(0) is the y-intercept

∴ The graph intersect the y-axis at point (0 , 15)

There is only one graph intersects y-axis at point (0 , 15)

The attached figure is the graph of g(x)

The graph which represents the polynomial function g(x) is:

the 2nd graph in the second line
