Solve the inequality 7-7x > 35. (a) write the solution in set-builder notation. (b) write the solution in interval notation. (c) graph the solution set.

a) {}

b) The interval notation is

c) See graph in attachment

Step-by-step explanation:

a) We want to solve the inequality

We group like terms to obtain

Divide both sides by 7 ;

or

{}

b) The interval notation is

c) Since the -4 is not part of the solution we use a hollow circle.

See attachment for the graphed solution

its an acute right triangle
