The cost of a new house can be represented by regression equation c= 120 f +90,000,where $120 is a cost per square foot and 90,000 is the cost of the lot . A new cost of a house is 438,000.

Aline has a slope of 1/4 and passes through point (0.4,-1/2). what is the value of the y-intercept?

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.

To find the inverse of a number a, one can use the equation f(c) = a-1/c=0 where c is the inverse of a use the secant method of finding roots of equations to find the inverse of a = 2.5 ,er = 0.001%
