y = -1/3x + 6
y = 3x + 3
y = (1/3x) - 6

Y=3x+3

Perpendicular lines have the product of their gradients =-1
since gradient of line 1 =-1/3
then  gradient of line 2 is
-1/3*m=-1
m=3

AlladinOne [14]

Answer:

Industries below 50% growth are

Personnel supply services, Warehousing and storage, Water and sanitation, Management and public relations, Business services, Equipment rental and leasing.

Step-by-step explanation:

In the graph percentage change is on the x axis and on the y axis all industries have been mentioned.

All the industries on y axis have the span over x axis representing the growth and salaries.

Out of 10 top industries only four industries have the growth of 50% which is evident from the graph.Those industries are Health Services,Computer and data processing, Cable television services and Residential care. Rest six industries are below 60% growth.So Ella should consider these industries to join.

Find X and Y and show please show calculations
torisob [31]

Answer:

Y = 90

X = 52

Step-by-step explanation:

Y is on a straight line. The sum of the angles on a straight line is 180.

The only other angle (that is marked) on this straight line, is a 90 degree one. So, <y + 90 = 180.

<y = 90.

Now <x + 38 = 90

so, x = 52
