Julie needs to cut 4 pieces of yarn, each with the same length, and a piece of yarn 7.75 inches long. let y represent the length of each of the equal pieces of yarn that julie decides to cut.
what is the equation that can be used to determine the total length of all of the yarn that she ends up cutting, t? is the graph of the equation continuous or discrete?

a) t=7.75y+4; discrete
b) t=7.75y+4; continuous
c) t=4y+7.75; discrete
d) t=4y+7.75; continuous

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
