Answer:
<h2>y = 2x+4</h2>
Step-by-step explanation:
#Rate of change
Rate of change is slope
If two points be (x1,y-1) and (X2,Y2) then
If a line be ax+by+c=0
#X and y inetercept
If a equation given y=mx+b
- To find x intercept put y=0
- To find y inetercept put x=0
#Zeros
To find the zeros spot out the x inetercepts
The x values of the x intercepts are the zeros
What goes into the bowl . . .
-- granola . . . 9-1/3 pounds
-- nuts . . . . . 9-1/3 pounds
-- raisins. . . . 9-1/3 pounds
How much is in the bowl all together ?
(9-1/3) + (9-1/3) + (9-1/3) = 27-3/3 = <em>28 pounds</em> .
After stirring, mixing, shaking, and resting, how much is
still in the bowl ?
Still 28 pounds. Nothing else went in, and nothing came out.
After a month, nobody has come into the store yet asking to buy
28 pounds of trail mix. So before it spoils or gets soggy, they decide
to split it up into 14 smaller packages, and see if more people will
buy smaller packages.
They make all of the small packages exactly equal.
How much trail mix is in each one ?
(28 pounds) divided by (14 packages) = <em>2 pounds/package</em>

Step-by-step explanation:
<u>Step 1: Define Equation</u>
2x + 10 = -4x - 9
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 4x on both sides: 6x + 10 = -9
- Subtract 10 on both sides: 6x = -19
- Divide 6 on both sides: x = -19/6
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 2(-19/6) + 10 = -4(-19/6) - 9
- Multiply: -19/3 + 10 = 38/3 - 9
- Add/Subtract: 11/3 = 11/3
Here we see that 11/3 does indeed equal 11/3.
∴ x = -19/6 is the solution to the equation.
