Ciara solved the exponential equation 3x+1 = 15 and her work is shown below. what is the first step she did incorrectly? (3 points) step 1: log 3x+1 = log15 step 2: (x + 1)log 3 = log15 step 3: log3 = log 15 over x plus 1 step 4: 0.477121 = 1.176091 over x plus 1 step 5: 0.477121(x + 1) = 1.176091 step 6: x + 1 = 1.176091 over 0.477121 step 7: x + 1 = 2.464975 step 8: x = 1.464975

Given the conditional statement, match the following. conditional statement: if two lines intersect, then their intersection is one point.

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
