Y2 - y1 1
--------- this equals - -----
x2 - x1 32
A decrease in the ratio 4:5 implies that :
New quantity:Old quantity = 4:5
Let the new quantity be 
So, the new quantity is 32
10. 8 divided by 4 is 2 times 2 is 4 8 plus 6 minus 4 is 10
The answer is x=-6.33333 (-19/3)
First, add like terms (12+7), which would equal to 19.
Then isolate the variable by subtracting 19 and adding it to the other side of the equal sign.
Now with this new equation of 3x=-19, isolate again by dividing 3 from x and do the same thing to the other side (-19/3).
The answer should be -6.33 repeating, but in algebra you would give a more simplified answer. This would be -19/3
Answer:
a. exponential
b. neither
c. exponential
d. linear
Step-by-step explanation:
b is neither because it is a quadratic function which forms a parabola:)
