Answer:
12x + 7 is the answer
Step-by-step explanation:
No it doesnt because it 8 is repeated and function has 1 outcome for each x
Answer:
9 years
Step-by-step explanation:
Simple interest for any amount p is given by
SI = P*R*T/100
where R is the rate of interest
T is the time period in years
given
P =$1500
R = 4%
T we have to find
SI = $540
Thus, putting the given value in SI = P*R*T/100
540 = 1500*4*T/100
T = 540*100/1500*4 = 9 years
Thus, It will take 9 years for Sam to earn $540
Which page is this in the book
Answer:
-2.61803398875, -0.38196601125
or
(-3±√5)/2
Step-by-step explanation:
First, expand. (2x+3)² = 4x²+12x+9=5
4x²+12x+4 = 0
Quadratic equations take the form ax²+bx+c = 0
In this case,
a = 4
b = 12
c = 4
You can solve with the equation x=(-b±√b²-4ac)/2a
Plug in:
(-12±√144-64)/8
(-12±√80)/8
(-12±√2^4×5)/8
(-12±4√5)/8
(-3±√5)/2
Final answer x = (-3±√5)/2
If you want decimal form: -2.61803398875, -0.38196601125
