Which equation is not a linear equation?
question 7 options:
a)
–4v + 2w = 7
b)
2
x
+
3
y
= 5
2x + 3y = 5 {"version": "1.1","math": "2x  +  3y  =  5"}
c)
x = -5
d)
x
4
= y

-4v + 2w = 7 is not a linear equation.

Step-by-step explanation:

A linear equation is one in the form:

y = mx + x

-4v + 2w = 7 is not a linear equation since it has v and w instead of y and x.

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..
