Consider the equation 2(ax+3)=4x−3(4x+8). For what value of a is there no solution to the equation?
erastovalidia [21]

Answer:

the value of a such that  there is no solution to the equation is a = -4.

Step-by-step explanation:

Let first simplify the expression presented on statement. The equation has no solution if and only if a is eliminated in the process and an absurd is the result (i.e. 0 = 7).

2\cdot (a\cdot x + 3) = 4\cdot x -3\cdot (4\cdot x + 8)

2\cdot a\cdot x +6 = 4\cdot x -12\cdot x -24

2\cdot a \cdot x+6=-8\cdot x-24

2\cdot a\cdot x +8\cdot x = -30

2\cdot (a+4)\cdot x = -30

(a+4)\cdot x = -15

To obtain an absurd, we need that a+4 = 0. Hence, the value of a such that  there is no solution to the equation is:

a = -4

Let prove the certainty of the result. We find that an absurd exist: (a = -4)

0 = -15

What’s the translation from the graph y=6x^2 to the graph y=6(x+1)^2
Leno4ka [110]

For this case, the main function is given by:

y = 6x ^ 2

We can apply the following transformation:

Horizontal displacements:

Assume h> 0:

To graph f (x + h) move the graph of f (x) h units to the left.

For h = 1 we have:

y = 6 (x + 1) ^ 2

Answer:

the graph y=6(x+1)^2 is the graph y=6x^2 moved 1 unit to the left.
