How do i solve and graph 3/4x + 8 < 41 on a number line
Tema [17]

Answer:

get the inequality first ! x<44

Step-by-step explanation:

3/4x+8<41 ( subtract 8 from both sides. 8 cancels out. and 41-8=33 )

3/4x<33 ( multiply both sides by 4/3)

3/4 ×4/3 = 1

33×33 =44

x<44

and to graph it your line should have a open circle on 44 and point to the left.

Determine the intercepts of the line. − 6 x + 3 y = − 7
egoroff_w [7]

Answer:

Step-by-step explanation:

-6x + 3y = -7

to find the x intercept, sub in 0 for y and solve for x

-6x + 3y = -7

-6x + 3(0) = -7

-6x = -7

x = 7/6 <=== ur x intercept is (7/6,0)

to find the y intercept, sub in 0 for x and solve for y

-6x + 3y = -7

-6(0) + 3y = -7

3y = -7

y = -7/3 <=== ur y intercept is (0,-7/3)

Use set builder notation to represent the following set. {... -3, -2, -1, 0} {x | x Z, x ≤ 0} {x | x N, x ≤ 0} {x | x R, x ≤ 0}
IceJOKER [234]

Answer:

\boxed{\boxed{\left\{x\ |\ x\ \epsilon\ Z,\ x \le 0}\right\}}}

Step-by-step explanation:

Set builder notation-

It is a notation for representing a set by enumerating its elements and stating the properties that its members must satisfy.

The given set is,

\left \{.... -3, -2, -1, 0 \right \}

This set is comprised of all negative integers. So symbol Z should be used in this case.

The set builder notation for this set is,

\left\{x\ |\ x\ \epsilon\ Z,\ x \le 0}\right\}

A computer company's stock costs $122 at the start of the day. At the end of the day it costs $93. By what amount did the stock'
Helga [31]

Answer:

the amount the stock changed over the day = $29

Step-by-step explanation:

The stock cost $122 at the start of the day . At the end of the day it cost $93. The amount the stock value changed can be calculated below.

The initial amount of the stock that days was $122 but at the end of the day it changes to $93. This means the stock cost decreases over the day.

Initial cost of stock at the day = $122

Final cost at the end of the day = $93

the amount the stock changes over the day = initial cost of stock at the day - final cost at the end of the day.

the amount the stock changes over the day = 122 - 93

the amount the stock changed over the day = $29

Generally, the stock decreased over the day.
