Lesson 6.2A solving systems using substitution algebra 1 x=y

Give the equations of two different lines that are perpendicular to the line 3x + 4y = 7.

In the xy-plane, if the parabola with equation passes through the point (-1, -1), which of the following must be true?

Acompany produces packets of soap powder labeled “giant size 32 ounces.” the actual weight of soap powder in such a box has a normal distribution with a mean of 33 oz and a standard deviation of 0.7 oz. to avoid having dissatisfied customers, the company says a box of soap is considered underweight if it weighs less than 32 oz. to avoid losing money, it labels the top 5% (the heaviest 5%) overweight. how heavy does a box have to be for it to be labeled overweight?
