Answer:

step below and graph

Step-by-step explanation:

y intercept: x=0 y = (-1/18) * 3 * (-3) * (-4) = - 2

y = -1/18 * (x³ - 4x² - 9x +36) ... leading coefficient: (-1/18 x³) -1/18

highest degree:( x³) 3

Aleks [24]

Answer:

$2c - 3$

Step-by-step explanation:

$3c - \frac{1}{3} = \frac{c}{2} = 2c - \frac{1}{3} (2) = 2c - \frac{2}{6} = 2c - 3$

The equation, y = 1250x + 22,850, gives the salary of a person as "y" after the stated number of years (x). Model the data with

Sidana [21]

Answer:

(a) $y = 6250x +17850$ --- The function

(b) $y = 49100$ --- The salary in 5 years

Step-by-step explanation:

Given

$y = 1250x + 22850$

Solving (a): Model the function around (1,24100) and (3,36600)

First, we calculate the slope

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{36600 - 24100}{3 - 1}$

$m = \frac{12500}{2}$

$m = 6250$

The function is then calculated as:

$y = m(x - x_1) + y_1$

$y = 6250(x - 1) + 24100$

$y = 6250x - 6250 + 24100$

$y = 6250x +17850$

Solving (b): Salary in 5 years

Here:

$x = 5$

So:

$y = 6250x +17850$

$y = 6250*5 +17850$

$y = 49100$

5/2 (7x-15)+x>13/2-3/2

Evgen [1.6K]

5(7x - 15) + 2x ≥ 13x - 3 multiplied both sides by 2 to clear the denominator

35x - 75 + 2x ≥ 13 x - 3 distributed 5 into 7x-15

37x - 75 ≥ 13x - 3 added like terms (35x and 2x)

24x - 75 ≥ -3 subtracted 13x from both sides

24x ≥ 72 added 75 to both sides

x ≥ 3 divided both sides by 24

Answer: x ≥ 3 Notation: [3, ∞)
