Semenov [28]2 years ago
5 0

Answer:

Option c)

Step-by-step explanation:

Given quadratic equation is

-2x^2+3x+4=7

-2x^2+3x+4-7=0

-2x^2+3x-3=0

Multiply the above equation into (-) we get,

2x^2-3x+3=0

To find the solution of quadratic equation ax^2+bx+c=0 is

[tex]x=-b

A group of vendors in a city determines that the equation yˆ=11.984x+15.341 models the total number of shorts they will sell eac
Virty [35]
Given the equation of a line of the form: y = mx + c, where m is the slope and c is the y-intercept.
y is the dependent variable while x is the independent variable.

The value c represents the initial value of the situation represented by the line. i.e. the value of the dependent variable (y) when the independent variable (x) is 0.

The value m is the slope and represents the amount with hich the dependent variable increases for each additional increase in the value of the independent variable.

Thus, given the equation: <span>y=11.984x+15.341,
where: y represents the total number of shorts sold each day, and x represents the day’s high temperature in °F.

The slope is 11.984 or approximately 12 and it represents the increase in the number of shorts sold for each additional increase in temperature.

Therefore, </span><span>the slope of the equation represents in context of the situation that '</span><span>The vendors will sell an additional 12 pairs of shorts for every 1° increase in temperature.' (option B)</span>

Yolanda purchased stock for $7,000 and paid a 1.5% broker fee. She sold it for $6,325 and paid a 0.5% broker fee. Compute her ne
goldfiish [28.3K]

Answer:

$-748.38

Step-by-step explanation:

Net proceeds = Total cost of selling the stock - Total cost of purchasing the stock

Total cost of purchasing the stock = $7000 + ($7000 x 0.015) = $7105

Total cost of selling the stock = $6,325 + ($6,325 x 0.005) = $6356.63

Net proceeds = $6356.63 - $7105 = $-748.38

Consider the function represented by the equation y-6x-9=0. Which answer shows the equation written in function notation with x
Marta_Voda [28]

Answer:

A. f(x) = 6x + 9

Step-by-step explanation:

The given equation is:

y - 6x - 9 = 0

We have to write this equation in function notation with x as the independent variable. This means that y will be replaced by f(x) and all other terms will be carried to the other side of the equation to get the desired function notation.

y - 6x - 9 = 0

y = 6x + 9

f(x) = 6x + 9

Therefore, option A gives the correct answer.
