The tables show linear relationships between x and y. Write an equation in slope-intercept form for each relationship.

Alenkinab [10]

The first thing you need to do is calculate the slope. pick 2 of the ordered pairs.

i'll use (1, 4) and (0, 6)

m = (6 - 4)/(0 - 1)
m = (2)/(-1)
m = -2

so the slope is -2. slope intercept form is written as y = mx + b and you have one part of that equation

y = -2x + b

to find b, use one of the selected points. i'll use (0, 6).

(6) = -2(0) + b
6 = b
b = 6

therefore:

y = -2x + 6

What is the slope of the function and what is it’s interpretation in the context of the problem

Romashka [77]

Answer:

3.5 is the slope and it is the rate of change.

Step-by-step explanation:

the slope is the number with the variable because you use the formula

y = mx + b

the slope is the rate of change.

By using algebra properties and trigonometric formulas we find that the trigonometric expression $\frac{1}{1 - \sin x} - \frac{1}{1 + \sin x}$ is equivalent to the trigonometric expression $\frac{2\cdot \tan x}{\cos x}$ .

<h3>How to prove a trigonometric equivalence by algebraic and trigonometric procedures</h3>

In this question we have trigonometric expression whose equivalence to another expression has to be proved by using algebra properties and trigonometric formulas, including the fundamental trigonometric formula, that is, cos² x + sin² x = 1. Now we present in detail all steps to prove the equivalence:

$\frac{1}{1 - \sin x} - \frac{1}{1 + \sin x}$ Given.

$\frac{1 + \sin x - 1 + \sin x}{1 - \sin^{2}x}$ Subtraction between fractions with different denominator / (- 1) · a = - a.

$\frac{2\cdot \sin x}{\cos^{2}x}$ Definitions of addition and subtraction / Fundamental trigonometric formula (cos² x + sin² x = 1)

$\frac{2\cdot \tan x}{\cos x}$ Definition of tangent / Result

By using algebra properties and trigonometric formulas we conclude that the trigonometric expression $\frac{1}{1 - \sin x} - \frac{1}{1 + \sin x}$ is equal to the trigonometric expression $\frac{2\cdot \tan x}{\cos x}$ . Hence, the former expression is equivalent to the latter one.

Ahmad’s goal is to exercise for a mean of 45 minutes per day for one week. For the first six days of the week, he exercised 35,

scoray [572]

Answer:

41.5

Step-by-step explanation:

To find the mean, your supposed to add all the numbers you have and divide by how many numbers there are. In this question your numbers are 35, 40,37,42,45, and 50.

If you add them all up you get 249. Your next step is to divide by how many numbers there are. Since there are 6, your equation will now be 249 divided by 6. Your answer is now 41.5

So on the 7th day Ahmad exercised for 41.5 minutes. If you need to round then maybe 41 minutes.
