The price of Stock A 9 AM was $12.84. Since then, the price has been increasing at the rate of $0.07 each hourAt noon the price of Stock 8 was \$13.34 . To decrease at the rate of $0.09 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
Answers
Answer:
In 3 hours 7 minutes and 30 seconds both stocks will be same.
Step-by-step explanation:
It is given that the price of Stock A at 9 AM was $12.84. The price has been increasing at the rate of $0.07 each hour.
The price of stock B at noon was $13.34 which is decreasing at the rate of $0.09 per hour.
So, let's set up equation for each.
Price of stock A equation is
y= 0.07 x +12.84
Price of stock B equation is
y= 13.34-0.09 x
Where 'x' is number of hours.
Let's set up both equations as same to find value for x.
0.07 x+12.84= 13.34-0.09 x
Add both sides 0.09 x
0.16 x+12.84= 13.34
Subtract both sides 12.84
0.16 x = 0.5
Divide both sides by 0.16
x=3.125
Let's change the decimal to minutes.
0.125*60= 7.5 minutes
So, in 3 hours 7 minutes and 30 seconds both stocks will be same.

A. Y= -1/3x + 14
B. Y= -1/3x + 10
C. Y= 3x - 12
D. Y= 3x - 26
Answers
Answer:
D
Step-by-step explanation:
The equation of the line passes through the point (12, 10) and parallel to the line y = 3x + 6 is Y= 3x - 26. The correct option is D.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the line passes through (12, 10) and is parallel to y = 3x + 6.
The slope of the line will be the same as that of the slope of the line which is parallel.
The equation of the line will be written as,
y = 3x + c
The y-intercept will be calculated as,
10 = (3 x 12 ) + c
c = -26
The equation of the line will be,
y = mx + c
y = 3x - 26
Therefore, the equation of the line passes through the point (12, 10) and parallel to the line y = 3x + 6 is Y= 3x - 26. The correct option is D.

Suppose a five minute overseas call cost $6.45 in a 10 minute call cost $11.40 the cost of the car in the length of the call are related write an equation to show the cost of the call of any duration approximately how long can you talk on the phone if you have $51 to spend
Answers
Answer:
The Equation for this is given as
C = $0.99m + $1.50
Where m = number of minutes
C = Cost of the call
If you have $51 to spend , the duration of the call is approximately 50 minutes
Step-by-step explanation:
Step 1
We find the difference in the cost of the calls.
$11.40 - $6.45
= $4.95
The cost for a 5 minute call =
$4.95 ÷ 5 = $0.99
Hence, The extra charges for the 5 minutes call =
$6.45 - $4.95 = $1.50
The Equation for this is given as
C = $0.99m + $1.50
Where m = number of minutes
C = Cost of the call
If you have $51 to spend, the number of minutes you would get is :
$51 = $0.99m + $1.50
$51 - $1.50 = 0.99m
$49.50 = 0.99m
m = $49.50/0.99
m = 50 minutes
Therefore, If you have $51 to spend , the duration of the call is approximately 50 minutes

Khali and Juan are using ribbon to decorate their art project. The ratio of the length of Khali's ribbon to the length of Juan's ribbon is 8:5 If Khali used a total of 72 cm of ribbon, how much did Juan use?
Answers
Answer:

2. Since they are parallel the slopes are the same
3. Insert slope and y-intercept into slope intercept form y-y=m(x-x)
y-(-2/3)=9/7(x-(0))
