Well, their speeds are (

is Jack's speed, and

is Richard's.

They, together, can paint 12 houses in 35 days. To get a single house, we only have to calculate

which is very close to 3 (a bit below)
A- 5
B- 4
C- 3
D- 8
E- -4
I think these are right hopes it help
E^2x - e^x -56 =0
(E^x - 8) (e^x + 7) = 0
E^x - 8 = 0
E^x +7 = 0
X = ln8 or x = 2.07944154...
For this case we have the following inequality:

To solve, we follow the steps below:
We divide between 5 on both sides of the inequality:

We multiply by -1 on both sides taking into account that the sense of inequality changes:

Thus, the solution is given by all values of "y" greater than or equal to 3.
Answer:

See attached image
The vertical axis represents the "y" axis
Answer:
(x,y) = (2 - 1)
Step-by-step explanation:
2x - y = 5
5x + 2y = 8
y + 2x = 5
2y + 5 x = 8
