Given the following system of equations: -4x+8=16 2x+4y=32 what action was completed to create this new equivalent system of equations? -2x+4y=8 2x+4y=32

For what value of (y) is 3^3/3^y =1/9

One astronomical unit (1 au) is about 1.496 alt tag missing. kilometers. if you wrote this number of kilometers in regular decimal notation (for example, 528 and 3,459 are written in regular decimal notation), how many zeros would your number have?

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.
