A) growth; B) decay; C) growth; D) decay
A is growth because the value of b raised to the exponent is larger than 1.
B is decay because the value of b raised to the exponent is smaller than 1.
C is growth because the value of b raised to the exponent is larger than 1.
D is decay because the value of b raised to the exponent is smaller than 1.
Answer:
Children 92 and 229 Adults
Step-by-step explanation:
1.5C + 2.25A = 653.25
C+A = 321
A = 321-C
Then
1.5C + 2.25(321-C) = 653.25
1.5C + 722.25 - 2.25C = 653.25
2.25C-1.5C = 722.25-653.25
0.75C = 69
C = 92
then
A = 321-92
A = 229
Answer: The models would be P
14.5 would be the answer for part B
Step-by-step explanation:
10x+3y=43
-9x-y=-20
From second equation,
y=-9x+20
Substitute third equation into first equation,
10x+3(-9x+20)=43
10x-27x+60=43
-17x=43-60
-17x=-17
x=1
y= -9+20= 11
Option B
