Answer:
D
Step-by-step explanation:
Let's solve your equation step-by-step.
x2+4=3x+8
Step 1: Subtract 3x+8 from both sides.
x2+4−(3x+8)=3x+8−(3x+8)
x2−3x−4=0
Step 2: Factor left side of equation.
(x+1)(x−4)=0
Step 3: Set factors equal to 0.
x+1=0 or x−4=0
x=−1 or x=4
Answer:
x=−1 or x=4
Answer:
-12
Step-by-step explanation:
numerator: -10 - 6 + 4 = -16 + 4 = - 12
denominator: (-0.5)(-2) = 1 Try this on your calculator.
Answer
-12 / 1 = - 12
Please try to be more specific. What I think you meant was "what is the area under the standard normal curve to the left of 2.6 standard deviations above the mean?" If that's it, the area can be found from a table of z-scores (look for z=2.6) or by using a calculator:
normalcdf(-100,2.6) = 0.995.
R = 8%/year
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving our equation:
r = (1/2)((2320/2000) - 1) = 0.08
r = 0.08
Converting r decimal to R a percentage
R = 0.08 * 100 = 8%/year
The interest rate required to get a total amount, principal plus interest, of $2,320.00 from simple interest on a principal of $2,000.00 over 2 years is 8% per year.
