Based on the following equations, state whether they are linear or non-linear. a) y = 2x

b) = – 3

c) = ^2 + 1

d) 4 + 2 – 10 = 0

e) = −3

f) x = 6

g) y = 1/x

h) y = 3/4x - 2

Step-by-step explanation:

a)it isnt a linear equation because there are two variables but it is a linear equation in two variables

able

b)no it isnt ,there no variables

c)no the highest power of the variable 2,a linear equation should not exceed the ppwer by 1

d)there arent any variables.therefore it isnt a linear eqaution

e)no it isnt,there is no variable

f)yes,this is a linear equation

g)yes, this a linear equation in two variable , but not a linear equation in one variable

h)yes ,this is a linear equation in two variable in two variable but not a limear equation in one variable

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
