I think you should believe whatever that person said
F(x) = x + 1

b
g(x) = cx - d
flip values of x and y in each equation, then solve for y:
x = y + a
-------
b
y = a - bx

Answer:
Area of parallelogram = 63 square units
Step-by-step explanation:
In the given parallelogram:
Height of parallelogram = 9 units
Base of parallelogram = 7 units
Find:
Area of parallelogram
Computation:
Using area of parallelogram;
Area of parallelogram = Height of parallelogram x Base of parallelogram
Area of parallelogram = 9 x 7
Area of parallelogram = 63 square units
Answer:
a) 30 000 000
b) -100 000 000
c) -160 000 000
d) 27 500 000
Step-by-step explanation:
You want to know how many bacteria are killed every 6 hours which is 1/10 so 50 000 000:10= 5 000 000 every 6 hours.
a) how many times does 6 hours fit in 1 day) 24÷6=4 so 4×5 000 000= 20 000 000 so then you subtract that from 50 000 000 because you want to know what remains which means 30 000 000 bacteria remain.
b) we already calculated 1 day so 30 000 000×5=150 000 000. Then you subtract that from the 50 000 000. 50 000 000- 150 000 000= -100 000 000
c) 1 day× 7= 30 000 000×7= 210 000 000- 50 000 000= -160 000 000
d) 5 000 000÷2= 2 500 000= 30 000 000- 2 500 000= 27 500 000 6 hours divided by 2 equals 3 hours so you also divide the bacteria by 2.
