The standard for is Y=-5/3x +3
Answer: 13
Step-by-step explanation:
Equilateral triangle means that all sides are equal
Soo
3x + 1 must be equal to 5x - 9
3x + 1 = 5x - 9
-2x = -10
x = 5
Substitute x as 5 into either side value
3(5) + 1 = 15 + 1 = 16
So, all sides equal 16
Which means that y + 3 also equals 16
y + 3 = 16
y = 13
Answer:
A
Step-by-step explanation:
(6,8) is the correct answer
Answer:
Length = 9 inches
Width = 13 inches
Step-by-step explanation:
Since width is 4 inches more than the length, we can let length be x, and so width would be x + 4
So we can say;
Perimeter = 2(L + W)
44 = 2{ (x) + (x+4) }
44 = 2 (2x + 4)
44 = 4x + 8
44 - 8 = 4x
36 = 4x
36/4 = x
9 = x
Since Length = x, length = 9
and since width = x + 4, width = 9 + 4 = 13
Hope this helps!
