X=31 is the answer. you divide both by 4x which the left side will cancel out and be just x and then you divide 124/4 and your answer will be 31.

HURRY PLS The length of time in hours of two airplane flights are represented by the following functions, where x is the number

mamaluj [8]

Answer:

h(x) = 0.0045x – 0.4

Step-by-step explanation:

The length of time in hours of two airplane flights are represented by the following functions, where x is the number of miles for the flight.

Flight A: f(x) = 0.003x - 1.2

Flight B: g(x) = 0.0015x + 0.8

Then the function

h(x) = f(x) + g(x) = (0.003 + 0.0015)x + (-1.2 + 0.8) = 0.0045x - 0.4.

Therefore, the third option is the right option. (Answer)

Find a formula for the product P of the solutions of the quadratic equation ax²+bx+c=0 .

Ede4ka [16]

Answer:

product of the roots= c/a

Step-by-step explanation:

The the two roots(α and β) of the quadratic equation ax²+bx+c=0 as given by shridharacharya formula are

$\alpha= \frac{-b+\sqrt{b^2-4ac} }{2a}$

$\beta= \frac{-b-\sqrt{b^2-4ac} }{2a}$

now product of the roots

αβ= $\frac{-b+\sqrt{b^2-4ac} }{2a}$ × $\frac{-b-\sqrt{b^2-4ac} }{2a}$

use formula (a+b)(a-b)= a^2-b^2 and solve we get

αβ= c/a

therefore product of the roots= c/a
