Assuming this is linear
write everything in thousands smaller

p=mx+b
b=initial amount
m=growth rate

city increases by 4 each year
in 2025, population is 450
find it after 2010, with 2010 being year 0 or x=0

so
2025-2010=15 years
15*4=60
increased by 60
450=result=increase+originalin2010
increase=60
450=60+original
minus 60
390=original

p=4x+390

Answer:

B. x = 2

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

check by substituting each given value of x into the function

x = 0 ⇒ y =  × 0² = 0

hence (0, 0) is correct

x = 2 ⇒ y =  × 4 = 3

hence (2, 4 ) is incorrect

x = 3 ⇒ y =  × 9 = 6  

hence (3, 6 ) is correct

x = 5 ⇒ y =  × 25 = 18  

hence (5, 18 ) is correct

Find the value of p for which the given pair of linear equations have infinitely many solutions for 4X + 3 Y - 4 is equals to ze
tino4ka555 [31]

Answer:

x=8/3

y= -20/9

Step-by-step explanation:

4X + 3Y -4 =0

Linear egquations must in

x + y = 0

so 4X + 3Y =4

THEN

3X + 9Y = - 12

Use the multiplier method to increase 88 pounds by 14% you must show your working
Komok [63]

Answer:

100.32

Step-by-step explanation:

First, we have to find 14% of 88

14% of 88 is = 88 x 14/100

                  = 12.32

Now we have to increase the number 88 by 14%, which means we have to add 14% of 88 (12.32) to the given number (88)  

88 + (14% of 88)

= 88 + 12.32

=100.32 pounds
