Which euation has a slope of -7 and a y-intercept of 8? a: 7x + y = 8 b: 8y + -7x = 1 c: y = 7x - 8 d: y = -7/8x

A: 7x+y=8 is the right answer, because if we move 7x to the other side we get: y=-7x+8

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
