Distance divided by time is speed. To find the rate of speed, divide 40 yards by 4.24 seconds which is approximately 9.43 yards per second. 9.43 yards per second is the rate of speed.
Let the length of one side of the original square be a.
The length of one side of the new square is (a+7) feet,
the area of the second square is
taking the square root of both sides:
a+7=11
a=4
Answer: 4 feet
Answer:
33333
Step-by-step explanation:
Answer:
the first option, (-4, 6)
Step-by-step explanation:
for this question, we can use the substitution method. this is where we substitute the coordinates in the answer choices into the given system of inequalities or equations to determine which one is true.
1. (-4,6)
x + 4y > 12
-4 + 4(6) > 12
20 > 12 is true
now we can substitute the second inequality.
3(6) > -4 + 6
18 > 2 is true, therefore making this set of points true.
it may be helpful to substitute the rest of the values of x and y into the inequalities to verify your answers :
5 + 4(2) > 12
5 + 8 > 12
13> 12 is true
3(2) > 5 + 6
6 > 11 is not true
the rest of the answer choices are also not true.
I hope this helped you!
Use the elimination method.
(-5x + y = 26)7
2x - 7y = 16
-35x + 7y = 182
2x - 7y = 16
-33x = 198
x = -6
Substitiute -6 for x in one of the equations.
2x -7y = 16
2(-6) - 7y = 16
-12 - 7y =16
-7y = 28
y = -4
The ordered pair would be (-6,-4)
