Mathematics
1 answer:
Lady_Fox [76]3 years ago
4 0

Answer:

Linear-1,2,3,6

Nin-Linear-4,5

Step-by-step explanation:

A linear equation is an equation in which the highest power of the  variable is 1.

Out of the given equations, the following are linear.

1) 5x_1 + x_2 - 7x_3 = 4

2) 5x_1 + 4.6x_2 + 12x_3 = -5

3) 3x_1 - x_3 = -5x_2 + 7

6) 6x_1 - 4x_2 + x_3 = 0

These equations on the other hand are nonlinear.

4) 3x_1x_2 + x_3 = 5

5) 4x_1^3 + x_2 = 5

No 4 contains a term which is the product of two variables therefore it is not linear.

No 5 contains a term whose highest power is 3. Such an equation is a Cubic Equation.

Turn 276% into a mixed number
AlladinOne [14]
Mixed number is (wholenumber)+(properfraction)
a proper fraction is a/b where a<b and b≠0

so

percent means parts out of 100
x%=x/100

so
276%=
276/100=
200/100+76/100=
2+76/100=
2+38/50=
2+19/25

How do you find the constant of proportionality<br>​
marta [7]

The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
