Answer:
A
Step-by-step explanation:
Because f(x) equals 4X
Answer:
273 frogs.
Step-by-step explanation:
The equation of growth in the number of frogs N = 137(1.09)^t where t is the time in years.
The year 2022 is 8 years after 2014 so the prediction for N in 2022 is:
N = 137(1.09)^8 = 273.
Answer:
55/9
Step-by-step explanation:
Not sure if this is correct or not but my answer is 48
These were my steps:
2(6+(12divided(3+1)-1
2x6=12. 3+1=4 4-1=3
12divided by 3 =4
So now all we have are 12 from (6x2) and 4 from 12div. By3
Then we multiply 12 with the 4 which =48
Hope that helped and made sense.
Answer:
y = 8/3x - 91/3
*view attached graph*
Step-by-step explanation:
3x +8y =4
-3x -3x
8y = -3x + 4
/8 /8
y = -3/8x + 1/2
Perpendicular lines have reciprocal slopes. So, the slope of -3/8 will now be 8/3
y = mx + b
y = 8/3x + b
-9 = 8/3(8) + b
-9 = 64/3 + b
3(-9 = 64/3 + b)
-27 = 64 + 3b
-64 -64
-91 = 3b
/3 /3
-91/3 = b
y = 8/3x - 91/3
Check your answer using (8, -9):
y = 8/3x - 91/3
-9 = 8/3(8) - 91/3
-9 = 64/3 - 91/3
-9 = -27/3
-9 = -9
This statement is true.
Hope this helps!
