So basically the question wants to confuse by saying “6 months” which is half a year, right? Do everything normally until 4yrs and then write into compound interest formula but with n as 1/2 which is root.
Yes they are equivilent because of the distributive property
which is
a(b+c)=ab+ac
or in this case
5(p+c)=5p+5c
if you don't believe it *cough* *cough* *Brainiac01* *cough* *cough*
then subsitute values
lets sayp=4 and c=3
5(4)+5(3)=5(4+3)
20+15=5(7)
35=35
tada
so the answer is yes
Answer:
None of the options are correct, the correct answers are: x = 0.967 and -2.067
Step-by-step explanation:
Comparing this equation with
a = 1, b = 1.1, c = -2
Using the almighty formula for solving quadratic equation:
Answer:
x = 2
y = 4
Step-by-step explanation:
y = x + 2
y = 3x - 2
From equation one, y = x + 2
So, substitute x + 2 for y into equation two
We have
x + 2 = 3x - 2
Add 2 to both sides of the equation
x + 2 + 2 = 3x - 2 + 2
x + 4 = 3x
Subtract x from both sides
x - x + 4 = 3x - x
4 = 2x
Divide both sides by by 2
4/2 = 2x/2
2 = x
x = 2
Substitute 2 for x in either of the equations to get y.
Using the first equation, we have
y = 2 + 2
y = 4
