Answer:
(0, -7)
Step-by-step explanation:
Since -4x is the slope, then -7 is the y-intercept.
For finding y intercept we substitute x=0
y = -7
The ordered pair would be
(0,-7)
hope this helps and is right. p.s. i really need brainliest :)
Answer: length = 24 ft
Width = 8 ft
Step-by-step explanation:
Let L represent the length of the barn.
Let W represent the width of the barn.
The area of a rectangular wall of a barn is 192 sq. Ft. This means that
LW = 192- - - - - - - - - - - - - - -1
It's length is 8 ft longer than twice it's width. This means that
L = 2W + 8
Substituting L = 2W + 8 into equation 1, it becomes
W(2W + 8) = 192
2W² + 8W = 192
2W² + 8W - 192 = 0
Dividing through by 2, it becomes
W² + 4W - 96 = 0
W² + 12W - 8W - 96 = 0
W(W + 12) - 8(W + 12) = 0
(W - 8)(W + 12) = 0
W = 8 or W = - 12
Since the width cannot be negative, then W = 8
L = 192/W = 192/8
L = 24
Answer:
The answer would be 17
Step-by-step explanation:
The answer would be 17 because if you add 12 plus 5 That would be your answer
Answer:
a = 6, b = -2, c = 3
Step-by-step explanation:
6x² - 2x + 3 = 0
a = 6, b = -2, c = 3
