Question 4 (Multiple Choice Worth 2 points)

[02.03]

The label on the car's antifreeze container claims to protect the car between −40°C and 125°C. To convert Celsius temperature to Fahrenheit temperature, the formula is C = 5 over 9 (F − 32). Write and solve the inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car.

−40 > 5 over 9 (F − 32) > 125; −40 > F > 257

−40 < 5 over 9 (F − 32) < 125; −40 < F < 257

−40 < 5 over 9 (F − 32); −40 < F

5 over 9 (F − 32) < 125; F < 257

−5x − 7 < −22 and −5x − 7 ≤ −3

Answer 2

can i get a free on :) haha

Answer 3

one

Answer 4

Which of the following is the correct graph of the compound inequality 4p + 1 > −7 or 6p + 3 < 33?
a number line with open circles at -2 and 5 with shading in between.
number line with open dots at ¨C2 and 5 and shading to the right of 5 and to the left of ¨C2.
number line with shading everywhere.
number line with open dot at ¨C2 and a closed dot at 5 and shading in between.

4p + 1 > −7 6p + 3 < 33
4p > -8 6p < 30
p > -2 p < 5
so -2 < p < 5
so P is between -2 and 5
and since it's not "≤" it would be open circles

Answer 5

I was pretty sure the reason people can only have one question open at a time was so that people can't post their entire homework for people to answer -.-

Answer 6

lol I post my homework because I don't want to type it in another box and so people don't think that I'm just saying random questions.

Answer 7

Solve and graph the absolute value inequality: |2x + 4| > 8
number line with open circles on −6 and 2, shading in between.
number line with closed circles on −6 and 2, shading going in the opposite directions.
number line with open circles on −6 and 2, shading going in the opposite directions.
number line with open circles on −2 and 2, shading going in the opposite directions.

|2x + 4| > 8 makes two inequalities
2x + 4 > 8 and 2x + 4 < -8 solve for both
2x > 4 2x < -12
x > 2 x < -6
so both open circle because there are no "or equal to" lines
x < -6 means shaded to the left of -6
x > 2 means shaded to the right of 2

Answer 8

The label on the car's antifreeze container claims to protect the car between −40°C and 125°C. To convert Celsius temperature to Fahrenheit temperature, the formula is C = 5 over 9 (F − 32). Write and solve the inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car.
−40 > 5 over 9 (F − 32) > 125; −40 > F > 257
−40 < 5 over 9 (F − 32) < 125; −40 < F < 257
−40 < 5 over 9 (F − 32); −40 < F
5 over 9 (F − 32) < 125; F < 257

so you start with -40 < C < 125
then C = 5 over 9 (F - 32)
substitute what C equals for C

Answer 9

Ok I got for the first question B and the second one is C that's what I got.

Answer 10

But the last one I don't really get.

Answer 11

Hello

Answer 12

yeah sorry, I got preoccupied.
first one I don't think is B?
C would be correct for the second

for the last
-40 < C < 125 replace C with 5 over 9 (F - 32)

Answer 13

I

Answer 14

Its ok and I think for the second one I think is A because there both open circles and not going to the left or right.

Answer 15

Solve and graph the absolute value inequality: |4x + 1| ≤ 5
number line with closed dots on −1.5 and 1 with shading going in the opposite directions.
number line with open dots on −1.5 and 1 with shading in between.
number line with closed dots on −1 and 1 with shading in between.
number line with closed dots on −1.5 and 1 with shading in between.

|a| < b makes a < b and a > -b
so |4x + 1| ≤ 5 makes
4x + 1 ≤ 5 and 4x + 1 ≥ -5
4x ≤ 4 and 4x ≥ -6
x ≤ 1 and x ≥ -3/2
so x is between -1.5 and 1
and closed circles

Answer 16

yeah first is A correct

Answer 17

Solve the compound inequality 6b < 42 or 4b + 12 > 8.
b < 6 or b > 5
b < 7 or b > −1
b < 7 or b > 1
b > 6 or b < 5

6b < 42 4b + 12 > 8
b < 2 4b > -4
b > -1
so b is between -1 and 2
and open circles

Answer 18

Which of the following is the correct graph of the solution to the inequality −8 greater than or equal to −5x + 2 > −38?
number line with an open dot at 2 with shading to the left and another open dot at 8 with shading to the right.
number line with an open dot at 8 and at 2 with shading in between.
number line with a closed dot on 2 and an open dot on 8 and shading in between.
number line with closed dots at 2 and 8 with shading between the 2 and the 8.

-8 ≥ -5x + 2 > -38
-10 ≥ -5x > -40
2 ≤ x < 8
so x is between 2 and 8
closed circle at 2 and open circle at 8

Answer 19

Which of the following is an equivalent form of the compound inequality −22 > −5x − 7 ≥ −3?
−5x − 7 < −22 and −5x − 7 ≥ −3
−5x − 7 > −22 and −5x − 7 ≥ −3
−5x > −22 and −7 ≥ −3
−5x − 7 < −22 and −5x − 7 ≤ −3

−22 > −5x − 7 ≥ −3
( ) can be taken out
( ) can be taken out
like (−5x − 7 ≥ −3)
^^^

Answer 20

is this right 3.B 4.D. 5.A

Answer 21

3. correct :)
4. correct :)

5. I made a typo sorry!
6b < 42 4b + 12 > 8
b < 7 4b > -4
b > -1
so b is between -1 and 7
and open circles

Answer 22

number 6 is b.

Answer 23

erm B would be correct for
Solve the compound inequality 6b < 42 or 4b + 12 > 8.

idk the problem numbers :P

Answer 24

lol I hope I get good luck. :)

Answer 25

K now what about 5 7 and 8

Answer 26

erm... take a guess first?

Answer 27

K I got B D C

Answer 28

5. almost! :)
it's supposed to be closed circles

7.
-8 ≥ -5x + 2 > -38
-10 ≥ -5x > -40
2 ≤ x < 8
so x is between 2 and 8
closed circle at 2 and open circle at 8 <--

8. try again?
−22 > −5x − 7 ≥ −3
( ) can be taken out
( ) can be taken out
like (−5x − 7 ≥ −3)

Answer 29

K i got C A C

Answer 30

5. D
7. C
8. A
