Please show working out in an equation form if possible
a) We were told that relationship between the value of the car and its age is linear. This means that it can be represented with a linear equation such as
y = mx + c
y is the dependent variable and in this case, it is the value of the car, V
x is the independent variable and in this case, it is the age of the car, a
The above equation is the slope intercept form equation where
m represents slope
c represents y intercept
The formula for determining slope is expressed as:
m = (y2 - y1)/(x2 - x1)
We were told that a 5 year old car is worth 14000. This means that
When x1 = 5, y1 = 14000
Also, the same car is worth 11400 after 2 years. This means that the car is worth 11400 after 7 years. Thus,
when x2 = 7, y2 = 11400
Thus,
slope, m = (11400 - 14000)/(7 - 5) = - 2600/2
m = - 1300
We would find the y intercept, c by substituting m = - 1300, x = 5 and y = 14000 into the slope intercept equation. Thus,
14000 = - 1300 * 5 + c
14000 = - 6500 + c
c = 14000 + 6500
c = 20500
Thus, by substituting m = - 1300 and c = 20500 into the slope intercept equation, the linear equation representng this scenario is
y = - 1300x + 20500
By replacing with the given variables,
V = - 1300a + 20500
b) When the car was new, it means that a = 0. By substituting a = 0 into the equation, we have
V = - 1300 * 0 + 20500
V = 20500
The value of the car was $20500 when it was new
Ron is x years old. His brother, Ray, is y years older than him. How old was Ray when Ron was first born?
Answer:
Ray was y years old when Ron was born
Step-by-step explanation:
Hey there!
The correct answer is y years old.
If he is y years older, that means that when Ron was 0, or when he was just born, Ray was y years older.
Have a terrificly amazing day! :D

If \large y=5 is the value of the expression more or less than 10?
A. y + 6.5
B. 50 + y
C. 5 y
D. 3 y + 2
Answer:
Step-by-step explanation:
y = 5
A) y + 6.5 = 5 + 6.5 = 11.5 > 10
B) 50 +y = 50 +5 = 55 > 10
C) 5y = 5*5 = 25 > 10
D) 3y + 2 = 3*5 + 2 = 15 + 2 = 17 > 10
Xander goes to the movies with his family. Each family member buys a ticket and two boxes of popcorn. There are five members of his family. Let t represent the cost of a ticket and p represent the cost of a box of popcorn. Explain how each expression describes the situation in a different way.
Answer:
t + 2p = cost of 1 family member
Step-by-step explanation:
Because there are 5 family members who buy 1 ticket and 2 boxes of popcorn, we must multiply the cost of one family member by five .
5(t + 2p) = total cost of the whole family.
We can distribute 5 and the above equation will become.
5t + 2(5)p ⇒ 5t + 10p = total cost of the whole family.
Hope that helps! :)
Answer:
Step-by-step explanation:
t + 2p = cost of 1 family member
since there are 5 family members who bought one ticket and 2 popcorn, we simply multiply the cost of 1 family member by 5.
5(t + 2p) = total cost of the whole family.
We can distribute 5 and the above equation will become.
5t + 2(5)p ⇒ 5t + 10p = total cost of the whole family.

What is the domain of the function y= (square root) x+6-7
Answer:
the third choice. x>_-6
Step-by-step explanation:
1. When you have the square root of (x+6), it shifts the graph 6 units to the left.
2. So the x values would start and include -6 and continue growing to the right.
3. So the domain (x values) of the equation is x is greater than or equal to -6
Sophia buys an apple that weighs 0.45 pound, a grapefruit that weighs pound, a navel orange that weighs pound, and a pear that weighs 0.5 pound. What is the order of the fruit from least
Answer:
The order of fruit from least to greatest weight is -
Apple , pear, navel orange, grapefruit
Step-by-step explanation:
P.S - The exact question is -
Given - Sophia buys an apple that weighs 0.45 pound, a grapefruit that weighs [tex]\frac{3}{4}[/tex] pound, a navel orange that weighs [tex]\frac{5}{8}[/tex] pound, and a pear that weighs 0.5 pound.
To find - What is the order of the fruit from least weight to the greatest weight ?
Proof -
Weight of apple = 0.45 pound
Weight of grapefruit = [tex]\frac{3}{4}[/tex] pound = 0.75 pound
Weight of navel orange = [tex]\frac{5}{8}[/tex] pound = 0.625 pound
Weight of a pear = 0.5 pound
As,
0.45 < 0.5 < 0.625 < 0.75
So, The order of fruit from least to greatest weight is -
Apple , pear, navel orange, grapefruit

.10x + .35x = 15(.20)
.45x = 3
x = 3/4.5
x = 6.67
Answer:
Step-by-step explanation:
[.1x+.35(15-x)]/15=.2
.1x+5.25-.35x=3
-.25x+5.25=3
-.25x=-2.25
x=9
So he will use 9lbs of 10% and 6lbs of 35%.
How wide is an 80" widescreen TV (MEASURED DIAGONALLY) if it has a height of 48”?
Answer:
64"
Step-by-step explanation:
Pythagoras theorem
√(80²-48²)
√4096
=64
Answer:
Width = 64"
Step-by-step explanation:
It forms a right angled triangle. We can use Pythagorean theorem to find the base of the triangle
Base² + altitude² = Hypotenuse²
base² + 48² = 80²
base² + 2304 = 6400
base² = 6400 - 2304
base² = 4096
base = √4096
base = 64
Width = 64"

Which square root is between 4 and 5?
O 10
O 14
O24
O 32
Answer:
√24 because it's lies on between of√16 and√25.
The only square root that falls between 4 and 5 is √24.
What is Number system?A number system is defined as a system of writing to express numbers.
We can estimate the value of each square root and see which one falls between 4 and 5:
The value of √10 is less than 4 because √10 is, 3.16
√14 is less than 4.5 because √14 value is 3.76
√24 is greater than 4.5 because √24 value is 4.89
√32 is greater than 5 because 5 x 5 = 25, and √32 is slightly smaller than 5.
Therefore, the only square root that falls between 4 and 5 is √24.

Answer:
100 degrees
Step-by-step explanation:
hi again,
By the linear pair theorem, Angle B + Angle E will equal 180 degrees
Angle B + 128 = 180
Angle B = 52
By the triangle Sum Theorem, Angle A + Angle B + Angle C = 180
48 + 52 + Angle C = 180
100 + Angle C = 180
Angle C = 80
Like I said, by the linear pair theorem, Angle C + Angle F will equal 180 degrees
80 + Angle F = 180
Angle F = 100
