the number y of new vocabulary words that you learn after x weeks is represented by the equation y=15 number 17 please help A-C.
ANSWER
QUESTION 17a
We were given the relation, [tex]y=15x[/tex], where y represents the number of new vocabularies learned, and x represents the number of weeks
Draw a horizontal line for number of weeks and a vertical line for number of vocabulary words using a scale of 5 units on both axes.
To graph this equation we need at least three points,
When
[tex]x=0[/tex], [tex]y=15(0)[/tex], [tex]\Rightarrow y=0[/tex]
So we plot the point [tex](0,0)[/tex]
When
[tex]x=1[/tex], [tex]y=15(1)[/tex], [tex]\Rightarrow y=15[/tex]
So we plot the point [tex](1,15)[/tex]
When
[tex]x=2[/tex], [tex]y=15(2)[/tex], [tex]\Rightarrow y=30[/tex]
So we plot the point [tex](2,30)[/tex]
Using a straight edge we draw a straight line through these three points.
The equation of the line is of the form [tex]y=mx[/tex], where [tex]m=15[/tex] is the slope.
This tells us that the 15 new vocabulary words are learned each week.
QUESTION 17 B
To find the number of new vocabulary words learnt after 5 weeks, we plug in [tex]x=5[/tex] in to the equation.
[tex]y=15(5)[/tex]
This gives us
[tex]y=75[/tex]
Therefore after 5 weeks, you learn 75 new vocabulary words.
QUESTION 17 C
We find the number of vocabulary words learned after 4 weeks and subtract it from the number of vocabulary words learned after 6 weeks'
To find the number of new vocabulary words learnt after 4 weeks, we plug in [tex]x=4[/tex] in to the equation.
[tex]y=15(4)[/tex]
This gives us
[tex]y=60[/tex]
Therefore after 4 weeks, you learn 60 new vocabulary words.
To find the number of new vocabulary words learnt after 6 weeks, we plug in [tex]x=6[/tex] in to the equation.
[tex]y=15(6)[/tex]
This gives us
[tex]y=90[/tex]
Therefore after 6 weeks, you learn 90 new vocabulary words.
We now subtract to get
[tex]90-60=30[/tex]
Therefore you learn 30 more vocabulary words after 6 wees than after 4 weeks.
The given equation y=15x + 17 represents the number of new vocabulary words you learn every week. Here, you learn 15 new words each week. You already know 17 words at the start (when x=0).
Explanation:The question is asking for the interpretation of the equation y=15x + 17, which represents the number of new vocabulary words, y, that you learn after x weeks. Here, 15 is the coefficient of x, which means that you learn 15 new words per week. The number 17 is the constant term, implying that even without any weeks passing (when x=0), you already know 17 words. Thus, after one week, you would know 15*1 + 17 = 32 words, after two weeks, 15*2 + 17 = 47 words, and so on.

Given that the strip is 10 times as big as the unit and the mat is 100 times as big as the strip, the mat is 1000 times bigger than the unit. This illustrates the concept of multiplication with powers of ten in real measurements.
Explanation:The question asks how many times the mat is bigger than the unit, given that the strip is 10 times as big as the unit and the mat is 100 times as big as the strip.
This maths problem involves the multiplication of sizes. Here's the step-by-step solution:
Each strip is 10 times as big as the unit, so if we assign U as the unit, the strip would be 10U. The mat is 100 times as big as the strip, which has been defined as 10U, so the mat would be 100 * 10U = 1000U.
Therefore, the mat is 1000 times bigger than the unit. This exhibits how we deal with real measurements and the use of powers of ten in multiplication.

If 2 rectangles have the same perimeter do they have to he congruent
Hey there!
Your answer is no.
I'll give an example to prove this wrong for you.
We have one rectangle with the dimensions of 2 x 6 units and another rectangle with dimentions of 4 x 4 units.
The perimiter of the first one is 16 because the four sides added up is 16: 2 + 2 + 6 + 6 = 16
The perimiter of the second is also 16. 4 + 4 + 4 + 4 = 16
So, they both have the same perimeter, but they are not congruent because their sides are different lengths.

One warehouse had 185 tons of coal, another one had 237 tons. The first warehouse delivered 15 tons of coal to its clients daily, the second one delivered 18 tons of coal to its clients daily. In how many days will the second warehouse have 1.5 times more coal than the first one? I NEED THIS IN 5 MINS
Given
One warehouse had 185 tons of coal, another one had 237 tons
The first warehouse delivered 15 tons of coal to its clients daily, the second one delivered 18 tons of coal to its clients daily.
Find out in how many days will the second warehouse have 1.5 times more coal than the first one.
To proof
Let us assume that the number of days of delivered the coal = x
Take two cases
First case
As given in the question
One warehouse had coal = 185 tons
The first warehouse delivered 15 tons of coal to its clients daily
(As first warehouse delivered 15 tons of coal to its clients daily than the total amount of coal decrease daily as days increase)
Than the equation becomes for first warehouse
= ( 185 - 15x)
( this equation represent the amount of coal left after x days)
Second case
second warehouse had coal = 237 tons
the second one delivered 18 tons of coal to its clients daily.
(As first warehouse delivered 18 tons of coal to its clients daily than the total amount of coal decrease daily as days increase)
Than the equation becomes for the second warehouse
= ( 237 - 18x)
( this equation represent the amount of coal left after x days)
As given in the question
the second warehouse have 1.5 times more coal than the first one
Thus
( 237 -18x ) = 1.5× ( 185 - 15x)
237 - 18x = 277.5 - 22.5x
22.5x - 18x = 277.5 - 237
4.5x = 40.5
x = 9
Therefore the second warehouse have 1.5 times more coal than the first one in 9 days.
Hence proved

The equation |x| = 77 has two solutions: x = 77 and x = -77. This is because the absolute value of a number reflects its distance from zero, regardless of the direction.
Explanation:The equation |x| = 77 has two solutions. This is because the absolute value of a number is its distance from zero on a number line, regardless of the direction. Therefore, both 77 and -77 have an absolute value of 77.
To solve for x, you would set up two equations based on the definition of absolute value:
x = 77-x = 77, which simplifies to x = -77So, the two solutions to the equation |x| = 77 are x = 77 and x = -77.

Dmitry runs 3.1 miles on Saturday,shown by the model. He runs 2.45 on Sunday. How much farther does he run on Saturday
Answer:
0.65 miles.
Step-by-step explanation:
Dmitry runs 3.1 miles on Saturday.
He runs 2.45 miles on Sunday.
On Saturday he runs 3.1 - 2.45 = 0.65 miles farther.
Dimitry ran 0.65 miles farther on Saturday than that during Sunday.
Distance travelled in miles by Dmitry on Saturday, d₁ = 3.1 miles
Distance travelled in miles by Dmitry on Sunday, d₂ = 2.45
The difference in the distance travelled by Dimitry during Saturday and Sunday can be calculated by subtracting the distance travelled on Sunday from that during Saturday.
Subtraction is the activity or process of determining the difference between two amounts or numbers. The phrase taking away one number from another is also used to describe the act of subtracting one number from another.
So,
The difference between the distances, d = d₁ - d₂
d = 3.1 - 2.45
