Question 8 From 1890 through 1990, the total number of
people T and the number of men M in the US
labor force can be modeled by the following
equations, where t is the number of years since
1890.
T= 0.0086t2 + 0.087t + 25.375
M = 0.0016t2 + 0.315t + 19.467
Find a model for the number of women in the US
labor force.

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
