What is the equation of the function that is graphed as line a​

Mathematics
1 answer:
levacccp [35]3 years ago
8 0

Answer:

<h2>y = -x - 1</h2>

Step-by-step explanation:

From the graph we have:

y-intercept = -1

x-intercept = -1

The slope-intercept form of an equation of a line:

<em>y = mx + b</em>

m - slope

b - y-intercept

Therefore we have: <em>y = mx - 1</em>

Put the coordinates of the x-intercept to the equation:

(-1, 0) → x = -1 and y = 0:

0 = -1m - 1       <em>add m to both sides</em>

0 + m = -m + m - 1

m = -1

Finally we have the equation:

<em>y = -1x - 1</em>

At the grocery store, Lindsay bought several pounds of strawberries. The strawberries cost $2.25 per pound. After she paid the c
yanalaym [24]
Let x equal the number of strawberries while y is the total amount of money she had.

The equation is: 2.25(x)+8.75=y.

Then, if she bought 4 pounds of strawberries, it would work as follows: 2.25(4)+8.75 is the total amount. That means 9+8.75 would be the total. Thus, the amount of money she started out with was 17.75 dollars.

Find the remainder for the quotient using either substitution or synthetic division.
zaharov [31]

(x - 5) is a factor of the polynomial function f(x) = x³ - x² - 17x -15 as there is no remaider.

<h3>What is a factor of a polynomial?</h3>

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given a polynomial function f(x) = x³ - x² - 17x -15.

If (x - 5) is it's factor then f(5) = 0.

∴ f(x) = x³ - x² - 17x -15.

f(5) = 5³ - 5² - 17(5) - 15.

f(5) = 125 - 25 - 85 - 15.

f(5) = 0.

So, the remainder is zero hence (x - 5) is a factor of the polynomial function f(x) = x³ - x² - 17x -15.
