The linear equation represents y = mx + b describes several real world situations such as
- Relation between printer and ink cartridges,
- Relationship between number of songs and how much is left on the card.
<u>Step-by-step explanation</u>:
Linear equations y = mx + b.
m is your rate of change.
b is your constant. This is the initial value of y. The value of y when x is 0.
Finally, y is the thing that depends on x.
Oh right, examples:
- I buy a printer for $100 and the ink cartridges cost $25 each. The relationship between ink cartridges and total cost.
total cost = 25(cartridges I buy) + 100 or y = 25x + 100
-
I get a $100 iTunes gift card for my birthday and then start buying $1 songs. The relationship between the number of songs I buy and how much is left on the card
amount left on card = -$1(songs bought) + 100 or y = -x +100
$1250
Use the formula i = prt
In this case, we don't know P or Principal amount
i = 400
r = .04 *found by diving 4/100*
n = 8
Set formula to solve for P like: P= i/r(n)
P=400/.04(8)
P= 400/.32
P = 1250
Answer:
240
Step-by-step explanation:
5x4x12=240
if you multiply the amount of sizes he can get times the amount of crust sizes he can get you get the pizza it's self (20)
now including the toppings (12) this means 20x12 gets you the amount of toppings on those induviduale pizza's.
Hope this helps!

Answer:
u = -3
Step-by-step explanation:
12 - 2u = 9u + 45
2u - 12 = -9u - 45
2u + 9u = 12 - 45
11u = -33
u = -33/11
u = -3
Answer:
a ) If r ⇒ p
If q ⇒ p
r ∪ q
If r∪p ⇒ ¬ r
∴ s
b) The argument is invalid
Step-by-step explanation:
The argument is invalid because we do not with precision if b), because we do not have enough information about it, and this is because the previous sentences does not mention information about the donkey. We cannot infer something when we do not have enough information.
