The width of a row of identical townhouses, y, and the number of townhouses, x, have a proportional relationship. The width of 5 townhouses is 105 ft. a. What is the constant of proportionality?

b. Write an equation that relates the width of a row of townhouses and the number of townhouses.

c. What would be the width of 9 townhouses in feet?

idk

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
