Answer:
y=4x-4
Step-by-step explanation:
Since this line rises 4 units for every 1 it moves to the right, it has a slope of 4/1=4. Also, since it intersects the y axis at the point (0,-4), b=-4.
Therefore, the equation is y=4x-4. Hope this helps!
Answer:
I don't know
Step-by-step explanation:
If it's the midpoint then MB=3x+3, but to find length set AM equal to one half AB
3x+3=(8x-6)(1/2) or 2(3x+3)=8x-6
2(3x+3)=8x-6
6x+6=8x-6
12=2x
X=6
First, determine the area of the triangle. When all sides of the triangle are given, you can determine its area through the semi-perimeter. This is the half of a perimeter.
s = (30 + 25 + 40)/2
s = 47.5
Then, we apply the Heron's formula:
A = square root [s(s-a)(s-b)(s-c)], where a, b and c are side lengths of the triangle
A = square root [47.5(47.5-30)(47.5-25)(47.5-40)]
A = 374.53 sq feet
To find the number of cows, divide the area by 50:
Number of cows = 373.53 ft2 / 50 ft2 per cow
Number of cows = 7.4906
The estimated number of cow is 7.
