Answer:
b
Step-by-step explanation:
just add x values and numbers
For this case we have an equation of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: growth rate
t: time
We then have the following equation:
y = 57 (1.31) ^ t
The initial number of bacteria is 57 and the growth rate is 31% per hour.
Answer:
B. The initial number of bacteria is 57 and the growth rate is 31% per hour
An architect plans to make a drawing of the room of a house. The segment LM represents the ceiling of the room. He wants to construct a line passing through Q and perpendicular to side LM to represent a wall of the room.

Answer:
x=12
y=
Step-by-step explanation:
Hey There!
to solve this problem we need to use the 30 - 60 - 90 triangle rule
So you are correct on x because the hypotenuse is 2x
24/2=12
y would equal
as you could see in the image down below
Answer:
x+1=4x-2
Subtract x from both sides
1=3x-2
Add 2 to both sides
3=3x
Divide 3
x=1
