-x-3y=-1 -x-3y=2 what do the two equations represent

Mathematics
1 answer:
murzikaleks [220]3 years ago
8 0

Answer:

Step-by-step explanation:

-x - 3y = -1

-3y = x - 1

y = -1/3x + 1/3.....slope here is -1/3 and y int is 1/3

-x - 3y = 2

-3y = x + 2

y = -1/3x - 2/3...slope here is -1/3 and y int is -2/3

these two equations represent parallel lines. Equations that have the same slope and different y intercepts mean the lines are parallel and never cross each others path.

last month you swam the 50-meter freestyle in 28.38 seconds. today you swam it in 27.33 seconds. what is your percent of change?
Nostrana [21]
The distance is the same(50 meters). So we will operate only with numbers 28.38 and 27.33.
The difference is 28.38-27.33=1.05
So the<span> percent of change is (1.05/28.38)*100%</span>≈3.7% 
The answer is 3.7%

Determine whether the relation is a function.<br><br> (4,0), (4,1), (5,2), (6,3), (6,4)
Alexxandr [17]

Answer:

The relation is not a function.

Step-by-step explanation:

In order for a relation to be a function, there can only be one output for every x value. If you were to graph this equation, it would not pass the vertical line test, as 4 has two outputs (0 and 1) and 6 has two outputs (6 and 4).

30 PTS!!!!! Cole needs to include at least 11​ mg and at most 22​ mg of iron in his diet each day. Cole plans to eat multiple ba
ser-zykov [4K]

Answer:

See explanation

Step-by-step explanation:

<u>Part A:</u> If Cole eats 3​ bananas each day. These 3 bananas contain 3\cdot 0.3=0.9 mg of iron.

Let x be the number of vitamins Cole takes. Each whole vitamin contains 4​ mg of iron, then x vitamins contain 4x mg of iron.

The total amount of iron Cole takes is

0.9+4x\ mg

Cole needs to include at least 11​ mg and at most 22​ mg of iron in his diet each day, so

11\le 0.9+4x\le 22

Solve it:

11-0.9\le 4x\le 22-0.9\\ \\10.1\le 4x\le 21.1\\ \\2.525\le x\le 5.275

The smallest number of vitamins - 3, the greatest number of vitamins - 5.

<u>Part B: </u>Cole continues to eat 3​ bananas each day. He pays \$2\cdot 7=\$14 for bananas per week.

If Cole spends a total of $20​ on bananas and vitamins this week, then he spent $20 - $14 = $6 on vitamins.

Let x be the number of vitamins Cole takes this week.

First 10​ vitamins are free, then x - 10 vitamins each cost $0.50 (he pays an additional dollar for every 2​ additional vitamins he purchases) and they cost

\$0.50(x-10)

This amount of money is exactly $6, so

0.50(x-10)=6\\ \\5(x-10)=60\\ \\x-10=12\\ \\x=22

This means Cole takes 3 vitamins per day (the whole number) and he is able to meet his iron requirement every day this week, based on  answer in Part A.

Classify the following polynomials according to the number of terms. Combine any like terms first.
11Alexandr11 [23.1K]

1) Combining like terms, we get x^2 + 5x, which is a binomial.

2) Combining like terms, we get x^3 + 3x^2, which is a binomial.

3) Combining like terms, we get 4x^3 + x^2 - x, which is a trinomial.

4) I can't answer this because there's an asterisk in place of the exponent.
