D. 3 since one vertex always face 2 vertex that you can draw a diagonal line with, its going to divide the pentagon to 3 different area which form 3 triangles

Your neighbor has been saving to buy a dirt bike. He has found a dirt bike for $836, which is 88% of the total amount he has sav

Gre4nikov [31]

Answer:

$936.32

Step-by-step explanation:

To solve this problem we need to find the remaining 12% of money our neighbor has saved since 88% was $836. To do this, we simply multiply $836 by 12%. Remember to change 12% into its decimal form (12% -> 0.12).

$836 x 0.12 = $100.32

Now, our last step is to add $100.32 to $836.

$836 + $100.32 = $936.32

Our answer is $936.32.

Answer: x = 11

Step-by-step explanation:

2x+5 = 3x-6

2x-3x = -6-5

-x = -11

x = 11

Double-check:
11*2= 22 11*3=33

22+5 = 27 33-6= 27

Write the equation of the following graph in vertex form.

Marat540 [252]

Answer:

Correct choice is 2. $f(x)=0.4(x+2)(x-5)$

Step-by-step explanation:

We have been given a graph of the quadratic function. Now we need to use that graph to find the equation of the graph in vertex form. By the way given choices written in intercept form so to be accurate we are going to find the equation in intercept form.

from graph we see that x-intercepts are at 5 and -2.

we know that if x=a is x-intercept then (x-a) must be factor.

So (x+2)(x-5) is the factor.

when leading coefficient is positive then graph opens upward.

so that means leading coefficient is 0.4

Hence correct choice is 2. $f(x)=0.4(x+2)(x-5)$
