Answer:
y = 5x
Step-by-step explanation:
If each calendar, <em>x</em>, sells for $5 each, you would multiply 5·x because $5 is how much you earn per calender. Therefore, your total income would be 5 times the number of calendars you sell, or in equation "language", y = 5x
Let
. The gradient of
at the point (1, 0, 0) is the normal vector to the surface, which is also orthogonal to the tangent plane at this point.
So the tangent plane has equation

Compute the gradient:

Evaluate the gradient at the given point:

Then the equation of the tangent plane is

Divide the number by 1,000,000 (1 million).
Micrometer is a millionth of a meter
11,562/1,000,000 = 0.011562
Solution :
For the bigger rectangle
Width of bigger rectangle = W
Length of bigger rectangle, L = 2W
For the smaller rectangle
Width , w = W+4
Length, l = L = 2W
Area, a =120 
Now we know,
Area = length x width






We get, either
(rejecting)
or 
∴ length of the bigger rectangle, 
= 2(6)
= 12 m
Length of the smaller rectangle, 
= 2(6)
= 12 m
Hence, the length of the two gardens is 12 m.
Answer:
x=10
y=30
Step-by-step explanation:
x=-2y+70
x=-2*3x+70
x=-6x+70
7x=70
x=10
y=3x
y=3*10
y=30
