Order of operation (), 2^2,x,÷,- 3(4+6+9+5+6+2) = -15. what is the questions for this?​

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

the formula of a slope:

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

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
