Answer:
One solution.
Step-by-step explanation:
Step 1: Write equation
5(x + 2) - 3 = 3x - 8x + 7
Step 2: Solve for <em>x</em>
<u>Distribute 5:</u> 5x + 10 - 3 = 3x - 8x + 7
<u>Combine like terms:</u> 5x + 7 = -5x + 7
<u>Add 5x to both sides:</u> 10x + 7 = 7
<u>Subtract 7 on both sides:</u> 10x = 0
<u>Divide both sides by 10:</u> x = 0
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
5(0 + 2) - 3 = 3(0) - 8(0) + 7
5(2) - 3 = 7
10 - 3 = 7
7 = 7
In brackets everything has to multiplied by 3. It there is no sign between its always multiply!!!
this means that it has to be
3 x X + 3 x 11
this means that we can also multyplay 3 by 11 now.
and that equals to 33. There fore the expansion will be:
3 x X + 33
we can also simplify 3 x X which would be 3x (as I mentioned before, It there is no sign between its always multiply!!!)
so the expansion for 3(x+11) is 3x + 33
Let the number be y.
One third of y = (1/3)*y = y/3
This is decreased by 6; y/3 - 6
And it equals 8
That means:
y/3 - 6 = 8
y/3 = 8 + 6
y/3 = 14
y = 3*14
y = 42
The number is 42.
I hope this helps.
The slope-point form of line:
We have the points (-9, 7) and (6, 2). Substitute:
The slope-intercept form of line:
.
We have the slope m:
Pu the coordinates of the point (6, 2) to the equation:
<em>add 2 to both sides</em>
