I dont know if this is multiple choice but A and D are functions
Two consecutive odd integers whose product is 143 are 11 and 13.
Answer:
Width of the house is 15.25 feet.
Step-by-step explanation:
Jason ran around his house = 3 times
In this run he covered total distance = 274.5 feet
Perimeter of the house = 2(length + width)
= 2(30.5 + width)
Perimeter of the house is the distance covered by Jason in one round.
So, distance covered in 3 rounds = 3[2(30.5 + width)]
274.5 = 6(30.5 + width)
274.5 = 6(30.5 + width)
45.75 = 30.5 + width
width = 45.75 - 30.5
width = 15.25 feet
Therefore, width of the house is 15.25 feet.
No
They are not equivalent.
Answer:
x=16, y=39
Step-by-step explanation:
to solve y=2x+7
Substitute 2x+7 for y in y=3x−9
y=3x−9
( solve this like a normal problem)
2x+7=3x−9 (Add -3x to both sides)
-x+7=-9 (Add -7 to both sides)
-x=-16 (Divide both sides by -1)
x=16
Now that you found x you can substitute this in the other problem.
y=3(16)-9
y=39
Hopefully this helped!
