Factor the quadratic expression to reveal the zeroes of the function it defines

Mathematics
1 answer:
Kazeer [188]3 years ago
4 0

Answer:

Below.

Step-by-step explanation:

This factors to the product of 2 binomials like (x + a)(x + b), where a and b are 2 numbers.

40 = 4 * 10 and 14 = 4 + 10 so the answer is

(x + 4)(x + 10).

If we expand this we will get back to the quadratic expression:

(x + 4)(x + 10)

= x(x + 10) + 4(x + 10)

= x^2 + 10x + 4x + 40

= x^2 + 14x + 40.

Una diseñadora de modas que confecciona trajes de noche, tarda 3 horas en cortar y 2 horas en coser cada vestido de fiesta. Para
ella [17]

For this case we define the following variables:

x: Number of party dresses

y: Number of suits

You have 30 hours per week to cut, that is, the first equation is given by:

3x + 3y = 30\\

It is also known that 25 hours per week are available for sewing, that is:

2x + 3y = 25\\

It has a system of two equations with two unknowns, solving we have:

3x + 3y = 30\\\\2x + 3y = 25\\

Multiplying the second equation by -1:

3x + 3y = 30\\\\-2x-3y = -25\\

Adding up:

x + 0 = 5\\\\x = 5\\

Substituting x in the first equation:

3 * 5 + 3y = 30\\\\15 + 3y = 30\\

Clearing and:

3y = 30-15\\\\3y = 15\\

y = \frac{15}{3}\\\\y = 5\\

Thus, per week, the designer can produce 5 party dresses and 5 suits working at her maximum capacity.

Answer:

5 Party dresses

5 Suits
