Lets use a rectangle as the example because I dont know what kind of shape you're looking for.
Area of a rectangle = length * width
Length (l) = 62
Width (w) = x
Area = 744
744 = 62 * x
Divide both sides by 62
744/62 = 12
12 = x
That means the width would equal 12
12 * 62 = 744
Answer:
b
Step-by-step explanation:
B. Y= (x - 10) ^ 4 - 81 OR y = x^4 - 20x +91
Verbs is the answer my friend
I would say the first choose that the vertical axis should use $0.50 intervals instead of $1.
Because this would make it much easier to read and understand and would it would also be more accurate.
Answer:
The answer is below
Step-by-step explanation:
The system of equations:
8x-9y+13z=11
-8x-5y+5z=15
3x+4y-8z=-10
The equations can be represented in matrix form as:
AX = B
X = A⁻¹B
Therefore:
