Using synthetic division to divide x³ + 2x² - x - 2.  Since (x + 1) is the factor, we can divide by -1.  See the attached file for the synthetic division.  After that, we are left with x² + x - 2.  This can easily be factored into (x + 2)(x - 1).  The remaining factors are (x + 2) and (x - 1).

9+3.5g=11-0.5g brainliest to whoever gives steps
kow [346]

Answer:

The answer is <u>g = 0.5</u>

Step-by-step explanation:

1. Your equation is :

<em>9+3.5g=11-0.5g</em>

2. First, multiply both sides by ten

<em>9 * 10 + 3.5 * 10 = 11 * 10 - 0.5 * 10</em>

3. Next we refine the equation

<em>90 + 35g = 110 - 5g</em>

4. Now, lets subtract 90 from both sides

<em>90 + 35g - 90 = 110 - 5g - 90</em>

5. Simplify

<em>35g + 5g = -5g + 20 + 5g</em>

6. We then add 5g to both sides

<em>35g + 5g = -5g + 20 + 5g</em>

7. Simplify again

<em>40g = 20</em>

8. Now, divide both sides by 40

<em>40g/40 = 20/40</em>

9. And finally, simplify once again to get your final answer.

<em>g = 1/2 or 0.5</em>

I hope this helped :)

Answer:

y= x-3

Step-by-step explanation:

The points are ;(0, -3), (5,2), (7,4), (10,7).

Plot the coordinates on a graph tool to visualize the graph

Select two points to find the slope ; take point (5,2) and (10,7)

m=Δy/Δx

Δy = 7-2=5

Δx=10-5 = 5

m=5/5 =1

The equation of the graph will be;

m= Δy/Δx

1=y-4/x-7

x-7 = y-4

x-7+4=y

x-3=y

y= x-3

According to Greg, perfect cherry pies have a ratio of 240 cherries to 3 pies. How many cherries does Greg need to make 9 perfec
vfiekz [6]
Simple, 3 goes in to 9, 3 times.  That would mean that to find the number of cherries, multiply 240 by 3.  Greg needs 720 cherries for 9 perfect cherry pies.
