Answer:
equation: x+3=y
Step-by-step explanation:
If the dog is 3 years older, then you take the cat + 3 to = the dogs age
Answer:
The correct choice is option D. y = 2x -12
Step-by-step explanation:
slope of the points (5,-2) and (8,4) is m = 2
y — intercept of the points (5,-2) and (8,4) is b = -12
Now, put it all together, and you'll get : y = 2x -12
Thé transformation is that the function moved 6 units down
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.
