Describe the location of point (-2,6,7) in three dimensional coordinate space

see the procedure

Step-by-step explanation:

we have

we know that

In Three dimensional space, the point has three coordinates

In this problem

The x-coordinate is equal to -2 ----> that means, 2 units back in the x-axis from the origin ( in the negative x direction)

The y-coordinate is equal to 6 ----> that means, 6 units forward in the y-axis from the origin ( in the positive y direction)

The z-coordinate is equal to 7 ----> that means, 7 units up in the z-axis from the origin ( in the positive z direction)

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
