Evaluate the following
a: |8| - 9 =
b: |8 - 9| =
Answers
Answer:
a = -1
b= 1
Step-by-step explanation:
8's absolute value is 8, so 8 - 9 is -1 but 8-9 = -1 and since the answer is in the absolute value bars, -1's absolute value is 1, so the answer will be 1
but in a, only 8 is in the absolute value bars, not the complete answer

PLEASE HELP!! I’ve got a car with an internal volume of 12,000 L. If I drive my car into the river and it implodes, what will be the volume of the gas when the pressure goes from 760 mmHg to 141.82 kPa?
Answers
Answer:
V2 = 8571.43L
Step-by-step explanation:
To solve for the V2, We can use V2 = P1V1 / P2
= 1.0 atm × 12,000 L / 1.4 atm
= 12,000 L / 1.4 atm
= 8571.43 L
Evaluate the function:
f(x)=x2−4x, find f(−3)
Answers
Answer:
f(-3) = 21
Step-by-step explanation:
To solve this, you can replace all x's with -3 and then solve to find the answer.
f(x) = x^2 - 4x
f(-3) = -3^2 - 4(-3)
f(-3) = 9 - (-12)
f(-3) = 21

Two types of tickets are sold to a play. Floor seats cost $45 each and balcony seats cost $25 each. A play sells 107 tickets and makes a total of $3,375. How many of each type of ticket are sold?
Answers
Answer:
floor seats=35
and the balcony seats =72
Step-by-step explanation:
Step one
given data
let the floor seats be x
and the balcony seats be y
so
45x+25y=3375-------1
x+y= 107----------------2
from 2, x= 107-y
put x= 107-y in 1
45(107-y)+25y=3375
4815-45y+25y=3375
collect like terms
-45y+25y= 3375-4815
-20y=-1440
divide both sides by -20
y=72
put y= 72 in eqn 2
x+72=107
x=107-72
x=35

3x-9=7x+14 solve for x
Answers
Answer:
x= - 23/4
Step-by-step explanation:
Add 9 to both sides of the equation:
3x -9 = 7x +14
3x- 9 + 9 = 7x +14 +9
Simplify:
3x -9 + 9 = 7x +14 +9
3x = 7x +14 +9
3x =7x +14 +9
Subtract 7x from both sides of the equation:
3x= 7x +23
3x -7x = 7x +23 - 7x
Simplify Again:
3x -7x = 7x +23 -7x
-4x =23
Combine like terms:
-4x =23
Divide both sides of the equation by the same terms:
14x/ 14 = 23/ -4
Cancel terms that are both the numerator and the denominator:
x= - 23/- 4
Answer:
x= - 23/4

1. Ryan and Rachel attended the weekend games at the neighborhood stadium and bought some food at the stands Ryan paid $7.10 for 3 corndogs and 1 coke Rachel paid $7.20 for 2 corndogs and 2 cokes. How much is each corndog?
Please help :( I’ll give you brainiest ♡
Answers
Answer:
$1.75
Step-by-step explanation:
Set up a system of equations where x is the cost of a corndog and y is the cost of a coke:
3x + y = 7.1
2x + 2y = 7.2
Solve by elimination by multiplying the top equation by -2
-6x - 2y = -14.2
2x + 2y = 7.2
Add them together:
-4x = -7
x = 1.75
So, the cost of one corndog is $1.75

If you deposit 4,300 into an account with an semi annual interest rate of 11% how much will you have after 1year
Answers
Answer:
FV= $4,786.01
Step-by-step explanation:
Giving the following information:
Initial deposit (FV)= $4,300
Number of periods (n)= 2 semesters
First, we need to calculate the semi-annual interest rate:
Semi-annual interest rate= 0.11/2= 0.055
Now, to determine the future value, we need to use the following formula:
FV= PV*(1+i)^n
FV= 4,300*(1.055^2)
FV= $4,786.01
