First we need to multiply all the inequality by 8 to get rid of the denominator
Now we need to divide all inequality by -3
When dividing or multiplying an inequality by a negative number the inequality sign changes, so
Answer: c ≤ -24
Answer:
It's 51 square inches. You can multiply 12x8 and subtract 9x5 from that.
Slope RS: 2/3
Slope ST: -3/2
Slope TU: 4/6 = 2/3
Slope UR: -1/5
Sides RS and TU have the same slope, so they are parallel.
The slope of side ST is the negative reciprocal of the slopes of sides RS and TU, so side ST is perpendicular to sides RS and TU.
Side UR is not parallel or perpendicular to any other side.
The quadrilateral is a trapezoid.
Use the pythagorean theorem. You should come out with C. Hope this helps!
