Answer:
(0,-7)
Step-by-step explanation:
the y-intercept is found when the x-value is equal to 0. In this case, we are finding a coordinate pair. First, plug in 0 for x.
7+y=4.3(0)
simplify
7+y=0
subtract 7 from both sides
y=-7
Make it an ordered pair,
(0,-7)
Answer:
4
Step-by-step explanation:
all you have to do is divide 12 by 3
The ratio would be 8:20 or 8 to 20
Area of a rectangular barnyard: A=6x^2+7x-20
A=6(6x^2+7x-20)/6
A=[(6^2)(x^2)+7(6x)-120]/6
A=[(6x)^2+7(6x)-120]/6
A=(6x+15)(6x-8)/6
A=(6x+15)(6x-8)/[(3)(2)]
A=(6x/3+15/3)(6x/2-8/2)
A=(2x+5)(3x-4)
A=bh
b=2x+5; h=3x-4
Answer: The possible dimensions of the barnyard are 2x+5 and 3x-4
