First of all why is there 2 similar equation connected to one another?
Second in order to solve this all you need to do is plug in the number and solve for x
For 485
85x+60=485
85x=420
X=5
Do the same thing and you get 3
F(4) is
F(x) = 4 when x is also 4
Answer:
b= 6/5
b = 1 1/5
Step-by-step explanation:
We can solve this using cross products
(3b-4) (b-2)
--------- = ---------
4 8
8* (3b-4) = 4*(b-2)
Distribute
24b -32 = 4b -8
Subtract 4b from each side
24b-4b -32 = 4b-4b-8
20b -32 = -8
Add 32 to each side
20b -32+32 = -8 +32
20b =24
Divide each side by 20
20b/20 = 24/20
b= 24/20
Dividing the top and bottom by 4
b = 6/5
b = 1 4/20
=1 1/5
The answer is B. Quadrant II
Just remember this concept instead.
The slope is this and that
