Answer:
red question= 8.5 yellow question=4.25
Step-by-step explanation:
Subtract the 2 equations
7x+2y=-19
- -x+2y = 21
--------------------------
8x +0y=-2
x= -1/4
The rule for differentiation for variable with exponents has the formula:
d/dx (xⁿ) = nxⁿ⁻¹
where n is the exponent
Thus, for the given equation, the solution is as follows:
y = 2x²
dy/dx = 2(2)x²⁻¹ = <em>4x
Thus, the derived equation of the given would now be 4x.</em>
