Answer: -20/7

Step-by-step explanation:

Seven times the sum of a number and 4 equals 8

Let the number be k

Sum of a number and 4

I.e

K+4.......(1)

Seven times the sum gives

7(k+4)=8

Open the bracket

7k+28=8

7k=8-28

7k= -20

K= -20/7

What is the difference between x and dx?
N76 [4]

This response is based upon your having had some background in calculus. "dx" is not introduced before that.

Take a look at the sample function y = f(x) = x^2 + 9. Here x is the independent variable; the dependent variable y changes with x.

Now, for a big jump: we consider finding the area under a curve (graph) between x = a and x = b. We subdivide that interval [a,b] into n vertical slices of area. Each of those slices has its own area: f(x)*dx, where dx represents the width of such subarea. f(x)*dx is the actual subarea. To find the total area under the curve f(x) between x= a and x = b, we add up all of these individual subareas between x = a and x = b. Note that the subinterval width is

b-a

dx = ---------- , and that dx becomes smaller and smaller as the number of

n subintervals increases.

Once again, this all makes sense only if you've begun calculus (particularly integral calculus). Do not try to relate it to earlier math courses.

When deriving the quadratic formula by completing the square, what expression can be added to both sides of the
liubo4ka [24]

Answer:

The element you add is      b^2 / 4a

Step-by-step explanation:

The element you add is      b^2 / 4a

Remember that

a x^2 + bx +c  \\= a ( x^2 +(b/a)x ) + c

So, in order to complete the square you add   (b/2a)^2

But when you multiply times  a   you get

b^2 / 4a

The demand for video recorders has been estimated to be Qv = 134 − 1.07Pf + 46Pm − 2.1Pv − 5I, where Qv is the quantity of video
stepladder [879]

Answer:

The Video recorders are inferior goods.

Step-by-step explanation:

As Q_{v} =134-1.07Pf+46Pm-2.1Pv-5I

where;

The price of the recorders films are increasing by a term 1.07 which gives that the Price is increasing by a little. Also adding the Price of video recorder is increasing by a factor 2.1 and the Revenue or income is increasing by a term 5 (Which is high) so, revenue and price are increasing leaving the quality of the voice recorder decreasing by a large margin for maintaining the balance.

As

                               Revenue =price*Quality

So, in conclusion the quality decreases and thus the video recorders are inferior goods.
