Answer: The answer is C.
Step-by-step explanation: This is because when you solve you get y=1/10x+6.5 this graph runs through the point (5,7) and is perpendicular to y=-10x+1. In order for two equations to be perpendicular their slopes will be the opposite.
Altitude forms a 30-60-90 (or 1-sqrt(3)-2) triangle. The hypotenuse is the equilateral triangle's side length, 12 centimeters. The altitude is the sqrt(3) side. 12 / sqrt(3) = 6sqrt(3). Therefore the altitude of the triangle is 6 * sqrt(3) centimeters.
First you want to change the fraction into a decimal on this one the decimal is going to be .3333 now your problem looks like 8-.3333x=16 now subtract the 8 and you get -.3333x=16 now divide by -.3333 and you get -48
The answer is 5 because that is the number that 4 corresponds to
