Answer:
5 chickens, 20 goats
Step-by-step explanation:
We can set up two equations and use substitution
There are 25 total goats and chickens, so
Goats have 4 feet and chickens have two, so
By solving for G in the first equation,
We can now use substitution,
We have 5 chickens, so we have 20 goats.
Let's double check:
It checks out!
Answer:
m=4/3 and b=5
Step-by-step explanation:
We want to find the equation of the line passing through (3,9) and (6,13).
We determine the slope using:
Let:
We substitute the points to get:
We now use the formula:
We substitute to get:
Multiply through by 3 to get;
We expand further to get:
This implies that:
We solve for y to get:
Therefore m=4/3 and b=5
