y=1/4x is:
stay on the 0-y. Move 1 up and 4 to the x side.
y=4x is:
stay on the 0-y. Move 0 up and 4 to the x side
y=2x is:
stay on the 0-y. Move 0 up and 2 to the x side.
y=1/2x
stay on the 0-y. Move 1 up and 2 to the x side.
<u>The system of equation</u>
First equation
x = 2y + 7
Second equation
3x - 2y = 3
<u>Substitute x with (2y + 7) in the second equation</u>
3x - 2y = 3
3(2y + 7) - 2y = 3
use distributive property
3(2y) + 3(7) - 2y = 3
6y + 21 - 2y = 3
add like terms
6y - 2y + 21 = 3
4y = 3 - 21
4y = -18
y = -18/4
y = -4.5
<u>Substitute y with its value, which is -4.5, in the first equation</u>
x = 2y + 7
x = 2(-4.5) + 7
x = -9 + 7
x = -2
<u>The solution is</u>
<u />(x,y) = (-2, -4.5)
The function rule that relates the number of miles traveled to the hours driven is d = 55t
<h3>What is speed?</h3>
Speed is the ratio of distance traveled by a body to the time taken.
The formula for calculating distance is expressed as:
Given that the speed is 55 miles per hour
55 = d/t
Cross multiply
d = 55t
Hence the function rule that relates the number of miles traveled to the hours driven is d = 55t
