Answer:

Point Form:

(-1/4, -7/8)

Equation Form:

x= -1/4, y= -7/8

Step-by-step explanation:

Answer:

x=-4, y=-6.5

Step-by-step explanation:

First, we need to find the value of x so

x+2=-2

-2 -2

x=-4

now plug the value of x, in the second equation

-3(-4)+2y=-1

12+2y=-1

minus 12 from both sides

12+2y=-1

-12 -12

2y=-13

divide by 2 to get the value of y

y=-6.5

2.) There are three nickels, four dimes, and four quarters in your pocket. You randomly pick three coins and place them on a counter. The first coin is a nickel, the second is a dime, and the third is a quarter.

A..3/110,

b.8/165,

c. 1/64,

d.10/273

Answers

Answer:

B.

Step-by-step explanation:

Total coins = 11 ( 3 + 4 + 4 = 11).

The probability of picking a nickel first = 3/11 ( 4 nickels out of 11 total).

The probability of picking a dime second = 4/10 = 2/5 ( 3 dimes out of 10 coins left).

The probability of picking the third coin as a quarter = 4/9 ( 3 quarters out of 9 coins left).

The probability of picking all three in that order = 3/11 x 2/5 x 4/9 = 8/165

Waylon is back-to-school shopping with his mom at a large department
store. He's picked out the following items: 3 pair of pants for $87 total, 4 t-shirts
for $48 total, 1 backpack for $35, 1 hoodie for $26, 1 pair of shoes for $37.
When they get to the register, they see this sign:

Answers

Answer:

Waylon's Purchase will cost $198.05, and section B depends.

Explanation: Section A is 85% of 233 since thats the total, making the answer to section A $198.05. The answer to section B depends because if he wants more school supplies, then yes, he would want to buy more things for better deals. But if he’s on a budget, then he wouldn't want to spend as much money since saving 20% on something over $300 is more than saving 15% on something over $200.

Answer:

B, you would save 15%

Step-by-step explanation:

87+48+35+26+37 = 233

and its over $200, so that means you would save 15%
