Answer:
Stephanie ran the fastest at 15 feet per second
Step-by-step explanation:
Frank ran the second fastest at 13.2 feet per second because it took him 60 seconds to run 792 feet, and 792/60 = 13.2
Debbie ran the third fastest at 12.08 feet per second because it took her 23 seconds to run 278 feet, and 278/23=12.086
Noah gets last place because it took him 551 seconds to run a mile, or 5280 feet, and 5280/551=9.58 feet per second
Answer:
The equation is ;
4x - y = 13
Step-by-step explanation:
The general equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
from what we are given, let us write the second equation in the general form
x + 4y = 10
4y = -x + 20
y = -1/4x + 20/4
y = -1/4x + 5
mathematically, when two lines are perpendicular, the product of their slope is -1
So for the second line with slope m2
m2 * -1/4 = -1
m2 = 4
So, using the general form, we have the equation as;
y = 4x + b
To get the value of b, we substitute the coordinates of the given point (3,-1)
-1 = 4(3) + b
-1 = 12 + b
b = -1-12
b = -13
So the equation is;
y = 4x - 13 which can be rewritten as;
4x-y = 13
