Which description best describes the solution to the following system of equations y = 2x + 3
y = -x + 6
lines y = -2x + 3 and y = -x + 6 intersect and the x axis
lines y = 2x + 3 and y = -x + 6 intersect at the y axis
line y = 2x + 3 intersects the line y = -x + 6
line y = 2x + 3 intersects at the origin

The line y = x + passes through (−3, 7) and is parallel to y = 4x − 1.

Scott harris can invest $7,000 in a 1-year cd that earns interest at an annual rate of 4 percent compounded monthly. the amount per $1.00 is 1.040742. he can also invest $7,000 in a 1-year cd at annual rate of 4 percent compounded quarterly. the amount per $1.00 is 1.040604. what is the difference in the amount of interest earned for each investment? a) $0.96 b) $0.81 c) $0.87 d) $0.88
