Which is the graph of the linear inequality y < 3x + 1?

1 answer:

5 0

Start at +1 on the x axis and then use 3/1 for rise over run. So you will start at +1 and then from that point rise 3 run 1

Over the last three evenings, Debra received a total of 110 phone calls at the call center. The second evening, she received 4 t

Elza [17]

Answer:

See below.

Step-by-step explanation:

Total = 110

Let calls on third evening = x

second evening = 4x

first evening = x + 8

=> x + 4x + x + 8 = 110

=> 6x = 102

=> x = 17

First evening = x = 17 calls

Second evening = 4x = 68 calls

Third evening = x + 8 = 25 calls

Complete the slope-intercept form of the linear equation that represents the relationship in the table.

nevsk [136]

According to the given table, the slope-intercept equation of the line is given by:

$y = -2x + 1$

The equation of a line, in <em>slope-intercept</em> form, is given by:

$y = mx + b$

In which:

The slope is m.

The intercept is b.

In this problem, we are given two points, (3,-5) and (-2,5).

The slope is given by <u>change in y divided by change in x</u>, hence:

$m = \frac{5 - (-5)}{-2 - 3} = -2$

Hence:

$y = -2x + b$

Point (3,-5) means that when $x = 3, y = -5$ , which is used to find b.

$y = -2x + b$

$-5 = -2(3) + b$

$b = 1$

Hence, the equation of the line is:

$y = -2x + 1$

What is the value of x in the equation 3(4x-1)-3x=5-(x-8)?

Setler [38]

12x-3-3x=5-(x-8)
9x-3=5-(x-8)
9x-3=5-x+ 8
9x-3=13-x
9x=16- x
10x=16
X= 8/5
