Anderson is a plumber and is paid a fixed amount just to make a house visit. the remainder of his fee, y, is determined by the number of hours that he works, x, as shown below.

plumber charges


which equation represents the graph?
y = 10x – 50
y = 10x + 50
y = 50x – 10
y = 50x + 10

y=10x+50 is correct equation.

B is correct

Step-by-step explanation:

Anderson is a plumber and is paid a fixed amount just to make a house visit. The remainder of his fee, y, is determined by the number of hours that he works, x,

We are given a graph to choose correct equation.

From graph we find two points on graph and then find the equation.

(0,50)  and  (20,250)

where, x represents number of hours worked.

y represents total earn by plumber.

Using two point formula to find equation of line.

Hence, y=10x+50 is correct equation.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
