Which is the contrapositive of pq?
If 3x + 7 = -5, then 4x + 12 = -4.
If 4x + 12 = -4, then 3x + 7 = -5.
If 3x + 7 3-5, then 4x + 12+ -4.
If 4x + 12 = -4, then 3x + 7 = -5.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

yes
