701 = 21 + 68w
701-21= 680
680/68=10
w=10
Answer:
the answer is c: s=40(1.1)^m, s=20(1.15)^m
Step-by-step explanation:
in option A, (0.10) and (0.15) make it exponential decay rather than exponential growth like it's supposed to be.
In option B, the rate of growth is supposed to be on the exponent, not the sales themselves in the equation
option c is correct I just finished the test
option d has the same mistake as a and b combined

Answer: its −2
Step-by-step explanation:
3*(5*x+2)-(2*(3*x-6))=0
Step by step solution :

STEP
2
:
Pulling out like terms
2.1 Pull out like factors :
3x - 6 = 3 • (x - 2)
Equation at the end of step
2
:
(3 • (5x + 2)) - 6 • (x - 2) = 0
STEP
3
:
Equation at the end of step 3
3 • (5x + 2) - 6 • (x - 2) = 0

5
:
Pulling out like terms
5.1 Pull out like factors :
9x + 18 = 9 • (x + 2)
Equation at the end of step
5
:
9 • (x + 2) = 0
STEP
6
:
Equations which are never true
6.1 Solve : 9 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
6.2 Solve : x+2 = 0
Subtract 2 from both sides of the equation :
x = -2
One solution was found :
x = -2
