Answer:
[tex]\displaystyle y=\frac{45}{7}[/tex]
Step-by-step explanation:
Direct Proportions
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
[tex]\displaystyle \frac{y}{x}=k[/tex]
Where k is a constant.
We know y=25 when x=140, and it's required to find the value of when x=36.
For any pair of values (x,y), their ratio is constant:
[tex]\displaystyle \frac{25}{140}=\frac{y}{36}[/tex]
Multiplying by 36:
[tex]\displaystyle y=36*\frac{25}{140}[/tex]
[tex]\displaystyle y=\frac{900}{140}[/tex]
Simplifying:
[tex]\mathbf{\displaystyle y=\frac{45}{7}}[/tex]

ED2021
The reasonable price of the car after 4 years will be $8618.
What is regression analysis?Regression analysis is a group of statistical procedures used in statistical modelling to determine the associations between a dependent variable and one or more independent variables.
Given that a dealership tracks the correlation between the age of its used cars and asking price for a car. The regression line is y = 12,338 – 930x, where x is the age of the car, in years.
The price of the car after 4 years will be calculated as follows:-
y = 12338 - 930x
y = 12338 - ( 930 x 4 )
y = 12338 - 3720
y = $8618
Therefore, the reasonable price of the car after 4 years will be $8618.

Evaluate 7y - 3y for y=3
7 . 3 - 3 . 3
= 21 - 9
= 12
Just substitute you y = 3 into the equation
Answer:
The correct answer is 12.
Step-by-step explanation:
To solve this problem, we must plug in 3 for each occurrence of y in the expression because we are given that y = 3. In this case, we will get the following:
7y - 3y
7(3) - 3(3)
To evaluate, we must simplify this expression. Due to the order of operations, we should compute the multiplication first. 7*3 = 21 and 3*3=9, so we can plug in these values into our expression.
21 - 9
Now, we can perform the subtraction.
21-9=12
Therefore, the correct answer is 12.
Hope this helps!

There are two rules for rounding:
1. If the number you're rounding is followed by a digit from 0 to 4 drop it
2. If it's followed by a digit from 5 to 9 add 1
Let's see them in action!

mr cadwell wants to purchase a motorcycle. he has financing options a and b to chose from, as shown below.
Option A-
Down Payment: $1,000
Monthly payment for 3 years: $85
Option B-
Down payment: $1,200
Monthly Payment for 3 years: $85
The purchase of the motorcycle is $3,500, including tax. Based on the info provided in the table, which statement is true?
Option B is better
Option A is better
Answer:
Option A is better.
Step-by-step explanation:
We will observe both plans one by one to determine which one is better i.e. which one will has less interest to pay.
So,
Option A:
Down Payment: $1,000
Monthly payment for 3 years: $85
The total amount in installments will be:
[tex]=Amount\ per\ month * months\\= 85*36\\=3060[/tex]
The total price of bike will be:
[tex]Total\ price = Downpayment +Installments\\= 1000+3060\\= 4060\\Interest = Total\ price - Purchase \\= 4060-3500\\=560[/tex]
Option B:
Down Payment: $1,200
Monthly payment for 3 years: $85
The total amount in installments will be:
[tex]=Amount\ per\ month * months\\= 85*36\\=3060[/tex]
The total price of bike will be:
[tex]Total\ price = Downpayment +Installments\\= 1200+3060\\= 4260\\Interest = Total\ price - Purchase \\= 4260-3500\\=760[/tex]
We can see that interest in Option A is less than interest in Option B that means Mr. Cardwell will have to pay less amount in Option A.
Hence,
Option A is better.
Which statement is true about figures ABCD and A'B'C'D?
Answer:
Step-by-step explanation:
To understand the transformation better we will take a point B first.
Coordinates of B → (3, 0)
When we rotate this point by 180° counterclockwise about the origin, rule to be followed,
(x, y) → (-x, -y)
By this rule, coordinates of B'' will be,
B(3, 0) → B''(-3, 0)
Now we translate the point B by 2 units right.
Rule for the translation is,
(x, y) → [(x + 2), 0]
Following this rule,
B''(-3, 0) → B'[(-3+2), 0]
→ B'(-1, 0)
We can conclude with the statement, "Figure ABCD was rotated by 180° about the origin followed by the translation of 2 units to the right" to get the new figure A'B'C'D' similar to pre-image ABCD.

hi
you have twi points A ( X;Y) and B ( X ; Y)
slope is : ( Yb -Ya) / (Xb -Xa )

A number increased by 15 is greater than 124. find the smallest integer that satisfies the inequality,
Answer:
This description translated into an inequality is
x + 15 > 124
x > 109
X is greater than 109
This means that the smallest integer that satisfies this inequality is 110 because X cannot be 109 or less; it is greater than 109.
We did not say 109.1 or 109.2 or 109.99 because it is asking for an integer, which cannot be a decimal.
Answer is 110
