What values of x and y satisfy the system of equations {2x+12y=−173x+2y=7? Enter your answer as an ordered pair, like this: (42, 53) If your answer includes one or more fractions, use the / symbol to separate numerators and denominators. enter your answer like this: (42/53, 64/75) If there is no solution, enter "no"; if there are infinitely many solutions, enter "inf."

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

what is the answer?

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
