Plz help I’m really confused The points (0.5. 1/10) and (7,1 2/5 ) are on the graph of a proportional relationship.

a. What is the constant of proportionality?

b. Name one more point on the graph.

c. Write an equation that represents the proportional relationship.

Julius sold five times as many computers as sam sold last year. in total, they sold 78 computers. how many computers did julius sell?

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

Solve the equation using the zero-product property. -3n(7n - 5) = 0 a. 0, -5/7 b. -1/3, -5/7 c. -1/3, 5/7 d. 0, 5/7
