Question 39 of 47 David has been tasked with tracking the number of bagels sold () at Freddy's
24-Hour Bagel Shop from 12:00 AM (x = 0) to 12:00 PM (x = 12). From 12:00
AM to 7:00 AM David the number of bagels sold is a function of the square of
the time (x) plus 4. From 7:01 AM to 12:00 PM David sells exactly 5 bagels
every hour. Which of the following graphs is representative of David's
findings?

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

thus, the first answer choice, y = sec x, is the correct one

x^3-4x^2+3x-2/x^2+1

step-by-step explanation:

factor the numerator and denominator and cancel the common factors
