Solve each linear quadratic system graphically. If necessary, round to the nearest integer

The triangles are similar. what is the value of x? show your work.

Find an equation for the linear function which has slope -10 and x-intercept -7

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.
