Answer:
transformations of function 3(-7(x+2))-4
- vertical stretch
- horizontal compression
- translates left
- translates down
- reflection across y-axis
slope intercept formula is y = mx + b.
Isolate the y. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 2x from both sides
2x (-2x) + 3y = (-2x) + 1470
3y = -2x + 1470
Isolate the y. Divide 3 from both sides
(3y)/3 = (-2x + 1470)/3
y = (-2x + 1470)/3
Simplify
y = (-2/3)x + 490
y = (-2/3)x + 490 is your answer
hope this helps
Answer:
The population will be 896 turtles 6 years later ⇒ B
Step-by-step explanation:
The exponential increasing formula is y = a
, where
- r is the rate of increase in decimal
∵ There are 300 turtles
∴ a = 300
∵ The population of the turtles exponentially increases 20% each year
∴ r = 20%
→ Divide it by 100 to change it to decimal
∵ 20% = 20 ÷ 100 = 0.2
∴ r = 0.2
∵ The time is 6 years
∴ x = 6
→ Substitute these values in the exponential formula above
∵ y = 300
∴ y = 300
∴ y = 895.7952
→ Round it to the nearest whole number
∴ y = 896
∴ The population will be 896 turtles 6 years later
