Y2=y1*3....
Answer:

Step-by-step explanation:
If y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation and
k = [tex]\frac{y}{x}[/tex]
Check this ratio for each ordered pair, that is
k = [tex]\frac{14}{7}[/tex] = [tex]\frac{42}{21}[/tex] = [tex]\frac{126}{63}[/tex] = [tex]\frac{378}{189}[/tex] = 2
Thus k = 2 and
y = 2x ← equation of variation

The length of x is 4
Step-by-step explanation:
The scale factor is Large/small where 10/8 which is DF/AC.
THE SCALE factor is 5/4.
To find the length of X is in AB we use the scale factor 5/4 and the corresponding DE.
5/4 = DE/AB
5/4 = 5/X
X = 4
To find Y in EF will use the corresponding BC which is 6.
5/4 = EF/BC
5/4 = Y/6
Y= 7.5

An oil company fills 1 over 10 of a tank in 1 over 5 hour. At this rate, which expression can be used to determine how long it will take for the tank to fill completely? (1 point)
a
1 over 5 • 10 hours
b
1 over 10 • 5 hours
c
1 over 5 • 1 over 10 hour
d
5 • 10 hours
Given that,
An oil company fills 1 over 10 of a tank in 1 over 5 hour.
To find,
How long it will take for the tank to fill completely.
Solution,
Let it takes t time to fill the tank completely. It can be calculated as follows :
[tex]t=\dfrac{\dfrac{1}{10}}{\dfrac{1}{5}}\ \text{hours}\\\\=\dfrac{1}{10}\times 5\ \text{hours}[/tex]
Hence, the rate is "1 over 10 • 5 hours ". The correct option is (b).

Graph the point (-2,3) and 3 more points using a slope of -1/2
Answer:
Step-by-step explanation:
(-2,3) k=-1/2
Find the equation of the line:
[tex]y=kx+b[/tex]
[tex]\displaystyle\\3=-\frac{1}{2}*(-2)+b\\\\3=1+b\\ 3-1=1+b-1\\2=b\\Thus,\\y=-\frac{1}{2} x+2[/tex]
The required 3 more coordinates are (0, 2), (1, 3/2), and (2, 1).
Given that,
To determine points using a slope of -1/2 and the point (-2,3).
Coordinate, is represented as the points on the x-axis and y-axis of the graph.
Here,
using the slope-intercept form of the equation,
y = mx + c
we have a point (-2, 3) and m = -1/2
Put point and slope in the equation,
3 = -1/2 * -2 + c
c = 3 - 1
c = 2
Now equation would be
y = -1/2x + 2
Now,
For x = 0
y = 2
Coordinate will be (0,2)
For x = 1
y = -1/2 + 2
y = 3/2
Coordinate will be (1, 3/2)
For x = 2
y = -1/2 * 2 + 2
y = 1
Coordinate will be (2, 1)
Thus, the required 3 more coordinates are (0, 2), (1, 3/2), and (2, 1).

7. Sound travels through air at 330 meters per second. How long will it take a bat's cry to reach its prey and echo back if the prey is 1 meter away? Round to the nearest thousandth of a second.
show your work pls and this is my 3rd time asking LOL
It takes the sound of a bat's cry 1/165 seconds to reach its prey and echo back
How to determine how long will it take a bat's cry to reach its prey and echo back?The given parameters are
Speed = 330 meters per second
Distance = 1 meters
The time taken to get to the prey is calculated as
Speed =Distance/Time
Substitute the known values in the above equation
So, we have
330 = 1/Time
Cross multiply the factors of the equation
So, we have
Time * 330 = 1
Divide both sides of the equation by 330
So, we have
Time 1 = 1/330
Similarly, the time taken to get from the prey is calculated as
Speed =Distance/Time
Substitute the known values in the above equation
So, we have
330 = 1/Time
Cross multiply the factors of the equation
So, we have
Time * 330 = 1
Divide both sides of the equation by 330
So, we have
Time 2 = 1/330
The time it takes a bat's cry to reach its prey and echo back is
Time = Time 1 + Time 2
So, we have
Time = 1/330 + 1/330
Evaluate the sum
So, we have
Time = 2/330
Simplify the quotient
So, we have
Time = 1/165
Hence, it takes the sound of a bat's cry 1/165 seconds to reach its prey and echo back
