Answer:
Step-by-step explanation:
Write the equations in the form y = mx + b
If the equation contains exponents then it is non-linear, if not then it is linear.
2xy = 3
This graph forms a curve so it is non-linear
y = 1x³ + 5
This equation is non-linear because it contains an exponent
y = x/3
y = 1/3x + 0
This equation is linear ( no exponent(s) )
2y = 1/2x
y = 1/4x + 0
This equation is linear ( no exponent(s) )
<span>5(x-3)= 7x-2(x+)1
5x - 15 = 7x - 2x + 1
5x - 15 = 5x + 1
-5x -5x
- 15 = 1
NO SOLUTIONS because -15 is not equal to 1 </span>

Answer:
k(-7) = - 89
Step-by-step explanation:
k (t) = 10t - 19
Let t = -7
k(-7) =10 * -7 - 19
=-70-19
-89
Answer:
Option A) 1.68
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 100
p = 15% = 0.15
Number of bags overfilled , x = 21
