Based on the tables, what is the solution to the equation 2(3)x = 3x + 3?
A)x=-1
B)x=0
C)x=1
D)X=6

Answers

Hello,

Answer C) x=1 for 3^1+3=3+3=6 and 2*3^1=2*3=6

Without the tables:
2*3^x=3^x+3
==> 2*3^x-3^x=3
==>3^x * (2-1)=3
==>3^x=3^1
==>x=1

Answer:

X will equal 1

Determine which ordered pair is a solution of y=8x.A. (0,8)
B. (-1,8)
C. (1.5,10)
D. (2,16)

Answers

we know that

If the ordered pair is a solution of the equation, then the ordered pair must satisfied the equation

we will proceed to solve each case to determine the solution of the problem

we have

$y=8x$ -------> equation $1$

case a) $(0,8)$

$x=0\ny=8$

For $x=0$

substitute the value of x in the equation $1$ and then compare the values of y

$y=8*0=0$

$0\neq 8$

The ordered pair case a) is not solution

case b) $(-1,8)$

$x=-1\ny=8$

For $x=-1$

substitute the value of x in the equation $1$ and then compare the values of y

$y=8*(-1)=-8$

$-8\neq 8$

The ordered pair case b) is not solution

case c) $(1.5,10)$

$x=1.5\ny=10$

For $x=1.5$

substitute the value of x in the equation $1$ and then compare the values of y

$y=8*1.5=12$

$12\neq 10$

The ordered pair case c) is not solution

case d) $(2,16)$

$x=2\ny=16$

For $x=2$

substitute the value of x in the equation $1$ and then compare the values of y

$y=8*2=16$

$16=16$

The ordered pair case d) is a solution

therefore

the answer is

$(2,16)$

y = 8x
y = 8(2)
y = 16
(x, y) = (2, 16)

The answer is D.

Rachel deposits $100 in a bank account and she gets 8% simple interest on it. Which linear model gives the return on her investment in terms of time t in years?a. R = 8t – 100
b. R = 8t + 100
c. R = 2t + 100
d. R = 88t + 100
e. R = 3t + 108

Answers

The answer would be B because the 100 stays in there and you are adding 8% per year. Hope this helps.
