Answer:
y = 1300 - 100x
Step-by-step explanation:
Zachary purchased a computer for $1300
The first step is to calculate the purchase he paid after 2 months
= 1,300-1,100
= $200
Then the purchase after 1 month is
= $200/2
= $100 per month
The purchase made after 4 months is
= 1,100-900
= $200
The purchase after a month is
= $200/2
= $100 per month
Therefore the equation that models the balance y after x months is
= initial amount of payment plan - amount per month
y= 1,300 - 100x
2/8 + 2/4
so, what you wanna do is make the numbers have the same denominator, or bottom part of the fraction.
to do this, you have to make 8 into 4, which would mean you divide 8 by 2. and since you do to the numerator what you do to the denominator, now 2/8 is equal to 1/4.
now, you have 1/4+2/4, and since the denominators are the same, you can just add the numerators!!
so your answer is 3/4!! hope i helped, let me know if you need clarification on anything!!
Answer:
1/18
Step-by-step explanation:
there are 12 marbles in the bag
P(choose red) = 2/12 = 1/6
P(choose blue after replacement) = 4/12 = 1/3
P(choose red, then blue with replacement) = (1/6)(1/3) = 1/18
The answer is A. (3,-1/2)
