29. The table below represents the relationship of the price of carrots to their weight in ounces in a market: Price Weight, in
Alinara [238K]

The proportional relationship that represents the market that sells their carrots at a lower rate per pound is: y = 1.6x.

<h3>What is a proportional relationship?</h3>

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

From the table, the rate is:

k = $8.8/4.4 = 2.

From the market, the rate is:

k = $4.8/3 = $1.6.

Hence the equation is y = 1.6x.

Graph of a cubic polynomial that falls to the left and rises to the right with x intercepts negative 3, negative 2, and 2
Tasya [4]

Answer:

f(x) = x3 + 3x2 − 4x − 12

Step-by-step explanation:

A polynomial which falls tot he left and rises to the right is a function with a positive leading coefficient. Its formed by the x-intercepts or zeros x = -3, -2 and 2. The zeros form the factors (x+3)(x+2)(x-2). Multiply the factors using the distributive property to find the function in standard form.

(x+3)(x+2)(x-2)

(x^2 + 3x + 2x + 6)(x-2)

(x^2 + 5x + 6)(x-2)

x^3 + 5x^2 + 6x -2x^2 - 10x - 12

x^3 + 3x^2 - 4x - 12

Given the function g(x)=−2x−8, evaluate g(0).
Vera_Pavlovna [14]

Answer:

g(0) = -8

Step-by-step explanation:

When you plug in a zero for the x the equation will look like

g(0) = -2(0) - 8

-2 times 0 = 0 so g(0) = -8

What is 6/7-2/3 equal to
Ann [662]


6/7-2/3

Make sure they have the same denominators which means looking for the GCF

So the GCF is 21 in this case

6/7= 18/21

2/3= 14/21

18/21 - 14/21= 4/21

The answer is 4/21

Find the product of (x- 5)
Alexus [3.1K]

Answer:

x² - 25

Step-by-step explanation:

Given:

(x-5)(x+5)

Find:

Product

Computation:

(x-5)(x+5)

(a+b)(a-b) = a² - b²

(x-5)(x+5) = x² - 5²

(x-5)(x+5) = x² - 25

Alternate:

(x-5)(x+5)

x² + 5x - 5x - 25

x² - 25
