△rst is mapped to △r′s′t′ using each of the given rules.

for which rules is △rst congruent to △r′s′t′?

select each correct answer.

a) (x, y)→(−x, y)

b) (x, y)→(−x, −y)

c) x, y)→(x, y−7)

d) (x, y)→(−7x, −7y)

e) (x, y)→(0.07x, 0.07y)

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  . 

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
