Assume that y is directly proportional to x. use the given x-value and y-value to find a linear model that relates y and x.
x = 5, y = 1010.

Step-by-step explanation:

To find a linear model, you need to use the formula y = kx and solve that for k.  k is the constant of variation, also known as the slope of a line.  Hence, the word "linear".

If y = kx and y = 1010 and x = 5, then

1010 = 5k so

k = 202

The linear model, then, is

y = 202x

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
