The expression −310+14y represents a submarine that began at a depth of 310 feet below sea level and ascended at a rate of 14 feet per minute. What was the depth of the submarine after 5 ​minutes?

X+ y = 5 ; x - y =3 solve using linear combination

Asquare picture with sides of 32 inches is to be mounted on a square mat with sides of 52 inches. find the area of the mat that will remain uncovered by the picture.

Given the equation y − 4 = three fourths(x + 8) in point-slope form, identify the equation of the same line in standard form. −three fourthsx + y = 10 3x − 4y = −40 y = three fourthsx + 12 y = three fourthsx + 10
