Answer:y=2x-12
Step-by-step explanation:
3 (2x + 1) = 21
6x + 3= 21
-3 -3
6x = 18
Divide each side by 6, and x equals 3.
3 (2(3) + 1) = 21
3 (6 + 1) = 21
18 + 3 = 21
Hope this helps! Can I please have brainliest so I can level up? Thank you!
You haven't provided the $ or % that he gets, but I will attempt to use algebraic terms to explain it instead.
If the salesman sells a car for $<em>a</em> and gets <em>b</em>% of the sale price as commission, then what you need to do is divide the <em>a</em> by 100, then multiply it by <em>b</em> to find out <em>b</em>% of <em>a</em>. This will be the commission that he will earn.
<em>a </em>/ 100 x <em>b</em> = commission earned in $
Edit
<em>You've now supplied me with the $ and %, let me explain it again.</em>
To find out the commission that he will earn, you divide 8,100 by 100 then multiply it by 9.
8,100 / 100 = 81
81 x 9 = $729 commission earned.
The area of a triangle with base 'b' and height 'h' is given by the formula:

It is given that the area of a triangle is
.
It is given that the base of the triangle is 5 times the height.
So, 
We have to determine the height of the triangle.
Since, 






So, 
So, h = 24 cm
Therefore, the height of the triangle is 24 cm.
Option 2 is the correct answer.
Answer:
(x, y) = (3, 26)
Step-by-step explanation:
I like to solve systems of equations like this by graphing. A graphing calculator easily shows the solution for both x and y.
(x, y) = (3, 26)
__
As an alternative, here, the equations can be subtracted.
y = f(x)
y = g(x)
0 = f(x) - g(x) . . . . subtract the second equation from the first
0 = 11x -7 -(3x +17)
0 = 8x -24 . . . . simplify
0 = x -3 . . . . . . .divide by 8
3 = x
Now, we can substitute into either equation:
y = g(x) = 3(3) +17 = 26
The solution is (x, y) = (3, 26).
