Find an equation of the line having the given slope and containing the given point.

saul85 [17]

Answer:

$y = 4x - 12$

Step-by-step explanation:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope and b is the y-intercept(value of x when y = 0).

In this question:

Slope 4, which means that $m = 4$ .

$y = 4x + b$

Contains point (1,-8).

This means that when $x = 1, y = -8$ . We replace this into the equation to find b. So

$y = 4x + b$

$-8 = 4(1) + b$

$b = -12$

$y = 4x - 12$

A 15-pound bag of wildflower seed covers 2424 square feet. how many pounds of seed does it take to cover 1 square foot

mariarad [96]

0.0061881188118812 pounds.

We can calculate this by doing 15/2424=0.0061881188118812.

We can confirm this is the correct choice by checking how many square feet 15 pounds would cover. To do this, we simply use this equation:
0.0061881188118812*2424=15 pounds.

Let U = {1, 2, 3, 4, 5, 6, 7, 8}, A =

mr_godi [17]

The equivalent set will be <u>A U B = {1, 2, 4, 5, 6, 8}</u>

<h3>Set theory</h3>

Given the following sets

U = {1, 2, 3, 4, 5, 6, 7, 8},

A ={2, 4, 6},

B = {1, 2, 5, 8},C = {1, 3, 7}

Required sets

A U B

Since union means that we are to write out all the values in the set A and B, hence the equivalent set will be;

A U B = {1, 2, 4, 5, 6, 8}
