Mazyrski [523]

Answer:

a) The rate of change is 3.5

b) The rate of change represents the price of a single cookie. $3.5

Step-by-step explanation:

a) To determine the rate of change along the graph, select a pair on the graph as;

(2,7) and (8,28)

Rate of change, m= change in y/change in x

m=28-7/8-2 = 21/6 =7/2 = 3.5

The equation of the relationship can be written as;

y=3.5 x + 0 where y is the amount collected and x is the number of cookies sold.

The slope here represents the price per cookie in $, $3.5

What is the degree of the polynomial 17x + 4.<br> Just write the answer like 1 or 2 etc.

fomenos

<h3>Answer: 1</h3>

Explanation:

The original expression is the same as $17x^1 + 4$ since $x^1 = x$

The degree of any polynomial is always the largest exponent. This applies to single variable polynomials only.

Therefore, the degree of $17x^1 + 4$ is 1. This is a linear polynomial, and it's also a binomial since it has 2 terms 17x and 4.

Which number has the same value as 3 X 1/10?

irakobra [83]

To find the same value as 3 x 1/10 you first have to solve 3 x 1/10

so how to do this is you have to make 3 into a fraction

so to make 3 into a fraction you can put 3 as the numerator and 1 as the denominator

so you multiply
$\frac{3}{1} \times \frac{1}{10} = \frac{3}{10}$
so 3/10 has the same value as 3x1/10

HOPE THIS HELPS!!!
