Given data:
The first equation is 3j +14=-5z.
The second equation is -10j=5z .
Add both the equations.
Substitute 2 for j in the first equation.
Thus, the value of j is 2 and z is -4.
Answer:
x = 2
Step-by-step explanation:
<u>Given</u>
2x^2-5+1=3
<u>Combine like terms</u>
-5 + 1 = -4
2x^2 - 4 = 4
<u>Add 4 to both sides</u>
2x^2 = 8
<u>Divide both sides by 2</u>
8/2 = 4
<u>Simplify</u>
x^2 = 4
<u>Square both sides</u>
<u>Simplify</u>
x = 2
<u>Answer</u>
x = 2
A function z=f(x,y) has two partial derivatives and y. These derivatives correspond to each of the independent variables and can be interpreted as instantaneous rates of change (that is, as slopes of a tangent line). Similarly, ∂z/∂y represents the slope of the tangent line parallel to the y-axis.
Answer:
Step-by-step explanation:
6.8x + 9.3 = -9.4 + 3.4(2 - 5x)
6.8x + 9.3 = -9.4 + 6.8 - 17x distribute
23.8x = -11.9 combine terms
x = -0.5 divide
There r 4 sides the bottom and the 3 sides
