Answer:

0.477121=−log(3x+7)+0.30103

Step 1: Flip the equation.

−log(3x+7)+0.30103=0.477121

Step 2: Add -0.30103 to both sides.

−log(3x+7)+0.30103+−0.30103=0.477121+−0.30103

−log(3x+7)=0.176091

Step 3: Divide both sides by -1.

log(3x+7)=−0.176091

Step 4: Solve Logarithm.

log(3x+7)=−0.176091

10log(3x+7)=10−0.176091

3x+7=0.666667

3x+7−7=0.666667−7(Subtract 7 from both sides)

3x=−6.333333

−6.333333

(Divide both sides by 3)

x=−2.111111

1. Over a period of 6 years (from 1980 to 1986) the house gained a value of 12000 dollars (109k-97k). 12000/6 gives you a rate of 2000 dollars per year. Because the initial price at t=0 is 97000, the function is 97000+2000t

2(a+7) - 7 = 9 what is the answer

REY [17]

Answer:

The answer is 1

Step-by-step explanation:

2(a+7)−7=9

Step 1: Simplify both sides of the equation.

2(a+7)−7=9

(2)(a)+(2)(7)+−7=9(Distribute)

2a+14+−7=9

(2a)+(14+−7)=9(Combine Like Terms)

2a+7=9

Step 2: Subtract 7 from both sides.

2a+7−7=9−7

2a=2

Step 3: Divide both sides by 2.

a=1
