7x+1 = (1/3)
2x + 2y = 28
Systems of equations.
Solve equation with single variable first.
7x+1 = (1/3) , x = (-2/21)
Substitute the value of x in second equation and solve for y.
2(-2/21) + 2y = 28, y = (296/21)
I’m assuming that isn’t the correct answer because you wrote the first equation incorrectly.
Answer:
10.) y = -5x + 7
12.) y = 3/2x - 8
Step-by-step explanation: Since you have to create a new line that us parallel, the slopes will be equivalent. So the mx value will not change. Now we can plug in the coordinates to find the value of b.
10.)
2 = -5(1) + b.
2 = -5 +b
b = 7
therefore...
y = -5x + 7
12.)
2(-5) = 3(2) + b
-10 = 6 + b
b = -16
therefore...
2y = 3x - 16
simplified:
y = 3/2x - 8

1 minute = 60 seconds
1 minute 35 seconds = 60 + 25 = 95 seconds
Speed = 400 meters / 95 seconds
Speed = 4.21 meters / second
The average speed of the horse is 25.0m/s
<h3>What is speed?</h3>
Speed is the rate of change of distance over time
The given parameters are:
- Distance (d) = 800 meters
- Time (t) = 32.0 seconds
The average speed of the horse is then calculated as:
This gives
Evaluate the quotient
Hence, the average speed of the horse is 25.0m/s
