Solve for 6x+4(3)=8(x+4)-2

Mathematics
1 answer:
ki77a [65]3 years ago
7 0

Answer: x = -9

Step-by-step explanation: 6x + 4(3) = 8( x + 4) -2

0pen brackets and collect like terms,

6x + 12 = 8x + 32 -2

collect the like term

6x + 12 = 8x + 32  -2

6x -8x = 32 -2 - 12

-2x = 18, divide through by  -2

Therefore x = -9

Find the midpoint of the segment with the following endpoints.<br> (4, 2) and (7, 6)
Artist 52 [7]

The midpoint of the segment with the following endpoints, (4, 2) and
(7, 6) is (5.5, 4).

How to determine the midpoint of a given segment?
The center point of a straight line can be located using the midpoint formula. We can use this midpoint formula to determine the coordinates of the supplied line's midpoint in order to discover its location on a graph. Assuming that the line's endpoints are (x₁, y₁) and (x₂, y₂), the midpoint (a, b) is determined using the following formula:
(a , b) ≡ (((x₁ + x₂)/2), ((y₁ + y₂)/2))

Let the line segment be AB having endpoints as A(4, 2) and B(7, 6);
also let the co-ordinates of midpoint be C = (a, b)
Using the given formula in the available literature,
(a, b) = ((4 + 7)/2, (2 + 6)/2)
Equating parts of the previous equation, we get,
a = (4 + 7)/2 = 11/2 = 5.5
b = (2 + 6)/2 = 4
Thus, the midpoint of the segment is (5.5, 4).

Find the axis of symmetry and the vertex of the graph of f(x)=−6x2+24x−20
asambeis [7]
The vertex will be when the velocity is equal to zero:

df/dx=-12x+24  (using the power rule for differentiation)

df/dx=0 only when:

-12x+24=0  add 12x to both sides

12x=24 divide both sides by 12

x=2, we find the y value to be:

y(2)=-6(2^2)+24*2-20

y(2)=-24+48-20=4

So the vertex is the point (2,4)

And the axis of symmetry is the line x=2

Now if you do not yet do calculus...

The vertex will occur midway between the two zeros.

6x^2-24x+20=0  (using the Quadratic Formula for simplicity)

x=(24±√96)/12

x≈(1.1835, 2.8165)

Now the vertex occurs at the average of the zeros...

x=(1.1835+2.8165)/2=2  (as we saw earlier)

y(2)=4

Vertex is at (2,4) and axis of symmetry is the vertical line x=2
