To solve this first distribute the 2, and then distribute the negative sign.

2(b+3)-(7+b)=-7

2b+6-7-b=-7

Combine like terms.

2b+(-b)=b

6+(-7)=-1

b-1=-7

Add 1 on both sides of the equation.

b-1+1=-7+1

b=-6

2(b + 3) - (7 + b) = -7

2b + 6 - 7 - b = -7

b = -6 + 7 - 7

b = -6

ElenaW [278]

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Decrease rate (d)= 7%

Number of periods (n)= 7 years

Current population (PV)= 48,000

First, to calculate the future value, we need to use the following decrease exponential formula:

FV= PV*[(1+d)^-n]

After 7 years:

FV= 48,000*(1.07^-7)

FV= 29,892

Identify the values of a,b, and c that could be used with the quadratic formula to solve the equation. Enter a as a positive int

Goshia [24]

Answer:

a=1

b= -6

c=48

Step-by-step explanation:

x^2=6(x-8)

x^2=6x-48

x^2-6x+48

a,b are the coefficients of x^2 and x

c is the constant value present

Therefore it is basically written as ax^2+bx+c

and comparing with the answer x^2-6x+48,

a=1, b= -6, c=48
