For which function will both ordered pairs (3,6) and (4,8) be solutions?

Answers

You just have to try them all:
Y=x+3 ≈ 6=3+3 ≈ 6=6 √
Y=x+3 ≈ 8=4+3 ≈ 8=7 X
So the first function doesn't work

Y=2x ≈ 6=2(3) ≈ 6=6 √
Y=2x ≈ 8=2(4) ≈ 8=8 √
Second function works

Y=x+4 ≈ 6=3+4 ≈ 6=7 X
Third function does not work

Y=12-x ≈ 6=12-3 ≈ 6=9 X
Fourth function doesn't work

So your answer is Y=2X :)

Some animals on farms eat hay to get energy. A horse can eat 20 pounds of hay each day. Write and evaluate an expression to find how many pounds a group of 17 horses can eat in two weeks.

Answers

Answer:

The amount of hay these 17 horses can eat in 2 weeks is 4,760 pounds.

Step-by-step explanation:

It is provided that a horse can eat 20 pounds of hay each day.

There is a group of 17 horses.

Compute the amount of hay these 17 horses can eat in 2 weeks as follows:

[tex]\text{Total amount of hay} = 20 \times \text{Number of days} \times \text{Number of Horses}[/tex]

                                [tex]=20\times 14\times 17\\\\=4760[/tex]

Thus, the amount of hay these 17 horses can eat in 2 weeks is 4,760 pounds.

Step-by-step explanation:

A :-) 4 ( x - 7 )^2 - 48 = 12
= 4 ( x^2 - 49 ) - 48 = 12
= 4x^2 - 196 - 48 = 12
= 4x^2 - 244 = 12
= 4x^2 = 12 + 244
= 4x^2 = 256
= x^2 = 256 by 4
= x^2 = 64

Henry incorrectly said the rate 1/5 pound/1/10 gallon can be written as the unit rate 1/50 pound per gallon . What is the correct unit​ rate? What was Henry's likely​ error?

Answers

Answer:

What is the correct unit rate?

The correct unit rate = 2 pound per gallon

What was Henry's likely​ error?

Henry's likely error was that instead of dividing the fractions he multiplied them

Step-by-step explanation:

Henry incorrectly said the rate 1/5 pound/1/10 gallon can be written as the unit rate 1/50 pound per gallon .

What is the correct unit​ rate?

The correct unit rate

= 1/5 / 1/10

= 1/5 ÷ 1/10

= 1/5 × 10/1

= 2 pound per gallon

What was Henry's likely​ error?

Henry's likely error was that instead of dividing the fractions he multiplied them

1/5 / 1/10

Henry calculated it : = 1/5 x 1/10 = 1/50

This is wrong.

The correct step is given below

1/5 / 1/10

= 1/5 ÷ 1/10

= 1/5 × 10/1

= 2 pound per gallon



Problem

The formula for the remaining volume of fuel in a car's tank is I-E\cdot DI−E⋅DI, minus, E, dot, D, where III is the initial volume of fuel, EEE is the fuel efficiency, and DDD is the distance traveled.

Carson drove a distance of 120120120 kilometers. He initially had 303030 liters of fuel, and his car's fuel efficiency is 100100100 cubic centimeters per kilometer.

What calculation will give us the estimated volume of fuel that remains in Carson's tank by the end of the drive, in liters?

Answers

Answer:

18 litres

Step-by-step explanation:

The formula for the remaining volume of fuel in a car's tank is expressed as;

V = I - E.D

where;

I is the initial volume of fuel,

E is the fuel efficiency, and;

D is the distance traveled.

Given

I = 30 litres

1m³ = 1000L

x = 30L

x = 30/1000

x = 0.03m³

I = 0.03m³

E = 100cm³/km

E = 100*10^-6m³/km

E = 10^-4m³/km

E = 10^-4m³/1000m

E = 10^-7m²

D = 120km

Convert km to metres

D = 120km = 120,000m

Substitute the results into the formula;

V = I - E.D

V = 0.03 - (10^-7)(120,000)

V = 0.03 - 0.012

V= 0.018 m³

Convert 0.018 m³ to litres

Since 1 m³ = 1000L

0.018 m³ = y

cross multiply;

y  = 1000 * 0.018

y = 18 litres

Hence volume of fuel that remains in Carson's tank by the end of the drive is 18 litres

Jacob earns $7.25 an hour at his part-time job, and earns $9 each time he mows the lawn for his mother. He graphs the amount of hours he works at his job (x) and the number of lawns he mows (y) to determine how to earn at least $300. Which type of boundary line should he use in his graph?

Answers

Answer:

$7.25 at part-time job $9.00 every time lawn mowed           so he would get 33.33 day so we will just say 33 times to get 300 dollars if he gets $9 for mowing.  And 41.37  hours to get $300 and he would have to use x and y graph to find the boundary line.

Each paragraph should be 5-7 sentences in length. Sticks and stones may break my bones, but words can never hurt me. This age-old adage has been passed down through the generations. Typically, its an offhand response from a parent to a child when someone has said something that hurt the childs feelings. After all, as long as theres no physical damage, then everything must be fine, right? Hurtful words are often treated as inconsequential. People assume they can be easily brushed aside and smoothed over with a flimsy apology on the part of the perpetrator. But the truth is, words can hurt in more ways than one and the effects often far outweigh any scrape or bruise. In todays world, our stories are no longer limited to simple word-of-mouth tales or even hard-bound books. Words are digital and far-reaching, passed around on websites, on social media, and in text messages. More often than not, the words we publish online are not really for the benefit of others, but for ourselves. Writer Gracy Olmstead says, in the world of internet and social media, another narrative has begun to reign supreme: namely, the self-narration. So, what happens when the words we use become more about self-gratification than genuinely helping or communicating with others? The result can be anything from shameless selfies to cyberbullying, and the effects are tangible. The Texas Education Code defines bullying as an act that exploits an imbalance of power and involves written or verbal expression. This has recently expanded to include digital forms of communication. These include sending vicious text messages, emails or instant messages, and spreading rumors or gossip by posting it to social networking sites. The sneaky thing about cyberbullying is that because its not physical, we underestimate its negative effects. With the anonymity and distance the internet provides, cyberbullies dont have to face the consequences of their actions, and often feel free to say whatever they want about others. History has proven that words can be just as potent weapons as if not more so than sticks and stones. During World War II, the Nazi regime employed propaganda to impress upon German civilians and soldiers that the Jews were not only subhuman but also dangerous enemies. The words of the German government became the defining narrative of an entire group of people. While this false propaganda seems a far cry from the problems facing teenagers today, they all demonstrate the impact of words. Novelist Chimamanda Ngozi Adichie put it simply when she said that the stories we tell are often about power. Power is the ability not just to tell the story of another person, but to make it the definitive story of that person, Adichie said. Perhaps the answer is not to fight to be heard, but rather to learn to listen. When we are empowered to tell our own stories or share our own points of view, our words can have positive, transformative effects. They can help people understand other experiences and see the world differently. Now that youve read about the effects words can have, what do you think? Has anyone ever said something about you that was hurtful or untrue? What did you do about it? How have you used words to solve a problem, bring people together, or share your own story?
