Answer:
No he was not correct
Step-by-step explanation:
The Equation is 15 x + 6 = 14 x + 5
now By the steps brandon used let us solve the question
Step 1 : Add 14 negative x tile to both sides
which will make the equation
15x + 6 - 14x = 14x + 5 - 14 x
x + 6 = 5 .......(ii)
Step 2: Add 5 negative unit tiles to both sides of equation (ii)
which will make the equation
x +6 - 5 = 5 - 5
x + 1 = 0 .........(iii)
Step 3: x =1 is the answer
but from equation (iii) we see that
x + 1 =0
by adding -1 on both sides
x + 1 -1 = 0-1
x = -1
So the step three done by Brandon is wrong which explains he was not correct
I'm assuming that the line is JKL in order of the points from left to right.
JK + KL = JL
(17-x) + (2x-7) = JL
Simplify.
10-x = JL
The answer to the question is y=<span><span><span>−<span>x2</span></span>+<span>10x</span></span>−<span>14</span></span>
Answer:
I THINK it's A
Step-by-step explanation:
Answer:
A) (17 ; 550)
B) $17/item
C) 550
Step-by-step explanation:
First we must calculate the intersection point of the two lines. Since in that point <em>y</em> has the same value in both equations, we can obtain <em>x </em>by equalling the two equations and then using that value for obtaining <em>y</em>:

So the value of <em>x</em> in the intersection point is 17. We now use this value with either one of the equations to obtain <em>y</em><em>. </em>Let's use the supply equation:

So the intersection point is (17 ; 550)
Supply and demand are in equilibrium when the amount of items on supply are the same as the ones on demand. That is the point were the two lines intersect, which means the selling price is the <em>x</em> coordinate and the amount of items is the <em>y</em> coordinate, so that is a selling price of <em>$17/item</em> with a number of items of <em>550</em>.
