First you would try to get the y variable by itself which you can do by subtracing 1/2x on both side. The equation would be y=-1/2x-15. You would then plug this into your graphing calculator and get the answer. If you do not have one, the x-intercept would be (0,-15) and the y-intercept would be (-30,0)
Well you need to divide 3.85 by 7 which would give you 0.55
2. (a＋b)²＝a²＋2ab＋b²
(5x－2)²＝(5x)²－2×5x×2＋2²
(5x－2)²＝25x²－20x＋4
4. (a＋b)²＝a²＋2ab＋b²
(2x＋5)²＝(2x)²＋2×2x×5＋5²
(2x＋5)²＝4x²＋20x＋25
∵a＝4, b＝20, c＝25
∴a＋b＋c＝4＋20＋25＝49
Hope my answer helped u :)
