Answer:
x=11, y=13
Step-by-step explanation:
3x-2y=7
3x-2(x+2)=7 . - x + = - -2*+2=-4
3x-2x-4=7
1x-4=7
x=7+4
x=11
y=x+2
y=11+2
y=13
Answer: 5/4
Explanation:
We have the same denominator so we can just add the numerator.
= 6/8 + 4/8
=10/8
10/8 can be simplified
=5/4
Answer:
C
Step-by-step explanation:
if you don't have from same x different outcomes is a function
think that x is a day you count votes, you can not get for the same day different y number of votes ( something is fishy then)
A. not a function because (6, -3) and (6, 3)
B. not a function because (4,7) and (4,2)
C. is a function
D. not a function because (2, -1) (2,1) (2,3)
-10.4
subtract 5.2 on each side because it’s the inverse operation
hope this helps!
Answer:
The possible parking lengths are 45.96 feet and 174.031 feet
Step-by-step explanation:
Let x be the length of rectangular plot and y be the breadth of rectangular plot
A rectangular parking lot must have a perimeter of 440 feet
Perimeter of rectangular plot =2(l+b)=2(x+y)=440
2(x+y)=440
x+y=220
y=220-x
We are also given that an area of at least 8000 square feet.
So,
So,
So,
General quadratic equation :
Formula :
So, The possible parking lengths are 45.96 feet and 174.031 feet
