Remember that x =r cos theta and y = r sin theta.  Thus, 

x + y = r (cos theta + sin theta) = 4, or

r (cos theta + sin theta) = 4, or
                        4
r = -------------------------------
       cos theta + sin theta

The linear equation that represent the left balance of sanjaya’s y after visiting x number of days is:

y = 10x + 500.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

From the data given, we have that:

  • The y-intercept is of 500.
  • The slope is of 10.

Hence the balance is given as follows:

y = 10x + 500.

Identify an equation in slope-intercept form for the line parallel to y=5x+2 that passes through (-6,-1).
Roman55 [17]

Answer:

D

Step-by-step explanation:

gradient for the line y=5x+2 = 5  from y=mx+c where m =gradient

parallel lines have equal gradients thus M2=5

equation for line passing through point (-6,-1) and gradient , m=5 will be

(change in y/change in x)=M2

(y--1/x--6)=5

y+1/x+6 =5

y+1=5(x+6)

y+1=5x+30

y=5x+29
