Answer:
y=9
Step-by-step explanation:
First we need to solve al addition and subtraction by performing the inverse operation. In this case, we need to add to reverse the subtraction
y/3 -4= -1
y/3= 3
Now we solve all multiplication and division again using the inverse operation, which in this case is multiplication, because the variable is being divided.
y/3=3
y=9
Thus we get that the value for y is 9.
Hope this helped!
Btw you're very pretty! <3
Answer:
a = 249 and b = 1.16
Step-by-step explanation:
Consider the provided information.
The exponential function for growth is: 
Here, a is the initial value and r is the rate of change.
It is given that the number of birds is 249.
It means a = 249
The rate is given 16%
r=0.16
Put the value of a and r in the above formula.
Now we will compare it with the exponential function form 
Therefore, a = 249 and b = 1.16
0-2+9=7 is the answer I think
#1
(56,7) is the co-ordinate of point B.
#2
(56,7)
It means that the ball has travelled 56yards .it is at the height of 7ft.
Answer: Definition: Ratio of the size of the map to its subject: Scale ... so scale = 1 cm / 100,000 cm = 1/100,000. - Scale ... STEP 1: - 2 cm represents 5 km
Step-by-step explanation:
STEP 1: - 2 cm represents 5 km - (write in full)
- STEP 2: - 1 cm represents 2.5 km - (divide so left side = 1)
- STEP 3: - 1 cm represents 250,000 cm - (convert to same units)
- STEP 4: - scale is 1 : 250,000 - (express as a representative fraction)
