Answer: a
Infinitely many
Step-by-step explanation:
Solve by substitution:
1) Solve 
for 
:
2) Substitute 
for in 
:
3) Simplify both sides of the equation:
4) Add -2 to both sides of the equation:
5) Simplify both sides of the equation:
Therefore, there are infinitely many solutions.
Solve by elimination:
You cannot solve this system by elimination
Solve by graphing:
The 
equations are on top of each other, therefore, the system of equations has infinitely many solutions.
Answer:
The complete factored form in (p-7)(5b^2+7)
Step-by-step explanation:
Formula for geometric series
an=a1(r)^n-1
a2=1/4(1/3)^1
a2=1/12
17 - x =36
subtract 17 on both sides
-x = 19
Now divide both sides by -1
Answer is B. -19
Strength [is proportional to] d^2
strength1/(d1)^2 = strength2/(d2)^2
800kg/(2cm)^2 = strength2/(3cm)^2
strength2 = 800 kg * (3 cm)^2/(2 cm)^2
strength2 = 800 kg * 3^2/2^2
strength2 = 800 kg * 9/4
strength2 = 1800 kg
