Which function is a linear function?

a.
1 − 3x2 = -y
b.
y + 7 = 5x
c.
x3 + 4 = y
d.
9(x2 − y) = 3
e.
y − x3 = 8

y+ 7 = 5x

Step-by-step explanation:

A linear function is a function in which the highest power of the unknown is 1 , that is , the highest power of the variables that are unknown will be 1.

From the question given:

A : 1  - = -y

The power of x is 2 , though the power of y is 1 but because of the existence of the power of x which is 2 , it is not linear

B : y + 7 = 5x

both the power of x and y is 1 , so it is a linear function

C: + 4 = y is not linear

D is also not linear

likewise , E is not linear

Therefore , B is the only linear function

Yes B is a linear function!

Step-by-step explanation:

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
