X + 19 + 7x + 9 = 180
8x + 28 = 180
8x = 180 - 28
8x = 152
X = 152 : 8
X = 19
Answer: <span>-x2 + 120x = 1,800

She plans on using the side of the barn as one side of her paddock so it has 3 sides. Since the width is shorter, it will be more efficient to have 2 widths (1 lengths and 2 widths). Because J</span><span>ill has 120 feet of fencing to use, you can get this equation:
120ft= 1L +2W
</span>1L= 120-2W
If you insert it into area formula it would be:
area= L*W
area= (120-2W) *W
area= 120W- 2W^2
-2W^2+120W= area
<span>Since x represent the width of the paddock and the area is 1800 the equation become
</span>-2X^2+120X= 1,800
I'm assuming you would plug in the miles, in this case leaving you with the equation y=3(26.5)+5.5 which equals 85. So i'm assuming your answer would be 85 min.
Answer:
The correct option is;
The graph is a line that rises steeply from left to right and passes through the origin
Step-by-step explanation:
The given equation is y = 110·x
Comparing the given equation to the general equation of a straight line, y = m·x + c
Where;
m = The slope of the straight line graph
c = The y-intercept
We have;
The slope of the given equation, y = 110·x = 110
The y-intercept, which is given by the constant c in the given equation = (0, 0)
Therefore, by the slope of the equation, for each unit increase in x, y increases by 110, therefore, the graph is a straight line that rises steeply and passes through the origin
Answer:
Hi there!
Your answer is:
A. Chemical change
Step-by-step explanation:
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances.
