Find all pairs of real numbers $(x, y)$ such that $x + y = 6$ and $x^2 + y^2 = 28$. if you find more than one pair, then list your pairs in order by increasing $x$ value, separated by commas. for example, to enter the solutions $(2,4)$ and $(-3,9)$, you would enter "(-3,,4)" (without the quotation marks).

Adding and subtracting matricesfind the value of each variable. x = and y = would

Martin likes to make flower bouquets that have 3 daffodils and 4 tulips per vase. a daffodil has a mass of d grams, a tulip has a mass of t grams, and the vase has a mass of u grams. the expression 5(3d + 4t + v) describes the mass of 5 bouquets. match each amount in the situation with the expression that represents it. situation expression number of bouquets mass of one bouquet mass of the tulips in one bouquet 4t mass of the daffodils in one bouquet 3d + 4t + v
