(a) has no solutions.

(b) has infinitely many solutions.

(c) has exactly one solution.

Answers

Answer and Step-by-step explanation:

Given

ax + by = c

qx + ry = s

(a) the equation has no solutions if a/q = b/r ≠ c/s, when this happens, we say the system of equations has no solution. For example

x + y = 3

x + y = 5

Subtracting first equation from the second we have:

0 = 2 which is impossible.

(b) the equations have infinite solutions if a/q = b/r = c/s, for example

x + y = 2

x + y = 2

Subtracting the first equation from the second we have

0 = 0, since this is always true, then it has infinite solutions.

(c) the equations have unique solutions if a/q ≠ b/r, for example

x + y = 2

x – y = 1

Adding the first and second equation we have

2x = 3, we can get x from here and definitely y, so we have just one solution.

you have a pie with 6 pieces and you eat 2. what fraction is that?​

Answers

Answer:

1/3 is eaten and 2/3 is left

Step-by-step explanation:

Say instead you cut the pizza into smaller pieces. How about cutting the whole pizza pie into 12 equal pieces? Each of five people takes one piece or 1/12 of the pie. Each piece is very small, much smaller than 1/6 of the pie or 1/4 of the pie. 5 of the 12 pieces or as a fraction 5/12 are gone. How many are left? 12 pieces minus 5 pizza slices equals 7 pieces left. Now 7 of 12 pieces pizza are left in your pie; that can be written as a fraction, too: 7/12.

Measurement of angles

on their first day, researchers explore a part of the ocean floor that is 60 feet below sea level. This depth can be represented by the integer -60. On their secon dive, researchers explore a deeper depth.
Write an inequality that represents the possible depth, d, of the researchers' second dive.

Answers

Answer:

d < - 60

Step-by-step explanation:

Given that:

Depth, d of ocean floor on first dive = 60 feets below sea level = - 60

Depth, d explored on second dive is deeper than that of fist dive

Hence, possible depth, d, explored on second dive can be represented by the inequality ;

Each tile is 3/2 feet by 3/2 feet. There are 10 tiles on the bathroom floor.



What is the area covered by the tiles?

Explain how you know.

Answers

9514 1404 393

Answer:

  22.5 square feet

Step-by-step explanation:

The area covered by one tile is the product of its dimensions:

  A = lw

  A = (3/2 ft)(3/2 ft) = 9/4 ft²

The area covered by 10 tiles is 10 times the area covered by one tile. The area covered is ...

  covered by tiles = 10 × 9/4 ft² = 90/4 ft²

  covered by tiles = 22.5 ft²

22 1/2 square feet is the area covered by tiles.

Part C. Naviah buys at least 8 but no more than 12 gallons of gas each week. The price of gas ranged from $2.25 to $2.50 per gallon each week. Write a compound inequality to model all of the possible amounts of money (m) Naviah spends on gas each week. Show or explain all work in detail

Answers

Step-by-step explanation:

Part A

At least 30 miles but less than 50 miles each week.

Required inequality:

30 ≤ x < 50

In 4 weeks:

120 ≤ 4x < 200Part B"At least" means equal or more than 30, hence 30 ≤ xLess than 50, hence x < 50Part C

At least 8 but no more than 12 gallons of gas each week, with the cost $2.25 to $2.50 per gallon.

Match the lowest and highest ends. This is converted as:

8*$2.25 ≤ m ≤ 12*$2.50

Simplified:

$18 ≤ m ≤ $30

Answers

Answer:

ok so in my math class I just learned this so sry if I am wrong but so

Answer:

Options 1, 3, 4, 7

Step-by-step explanation:

I'm guessing you meant the expression 3/5^3.

The base would be 3/5 because that is the number that the exponent is raising.

The exponent is 3 because that's the small number above and to the right of 3/5.

The expanded form is 3/5 × 3/5 × 3/5 because there's an exponent of 3. An exponent means you multiply the number by itself, the number of times it's being raised to. The exponent is 3 and 3/5 is being multiplied 3 times.

The solution would be 27/125 because when you multiply fractions, you just multiply straight across. 3 × 3 × 3 is 27 and 5 × 5 × 5 is 125.

I hope this makes sense, it's kinda hard to make it understandable without being able to actually talk to you.

Also when you graph it, it does not become a line. I can attach an image for evidence (Credits to other person who answered and commented on my answer thanks for finding my mistake.)

The second one has an exponent on the x, so it is not linear.
