determine the equivalent system for the given system of equations.
4x − 5y = 2
10x − 21y = 10

a) 4x − 5y = 2
3x − y = 4

b) 4x − 5y = 2
24x − 47y = 22

c) 4x − 5y = 2
10x + 3y = 15

d) 4x − 5y = 2
14x + 26y = 12

What is the measure of angle z in this figure? enter your answer in the box. z = ° two intersection lines. all four angles formed by the intersecting lines are labeled. clockwise, the angles are labeled 43 degrees, x degrees, y degrees, and z degrees.

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.
