Multiply the first equation with (-1)
you should get this

-6r + 3t = -6
6r + 8t = -16

start to eliminate

11t = -22

divide by 11

t = -2

substitute

6r - 3(-2) = 6
6r + 6 = 6
6r = 6 - 6
6r = 0
r=0

Which of the following equations represents a line with a negative slope and a negative y-intercept?

Luden [163]

The answer is A because u can subtract the 3x to get 2y by itself then divide by 2 to completely get y by itself and it would be y=-3/2x - 9/2

Answer:

$f(x)=10000(1.23)^x$

Step-by-step explanation:

We are going to apply algebra to solve for the exponential growth

we know that the expression for the exponential formula is

$y = ab^x.$

where

a = the amount before measuring growth or decay

= 10,000

r = growth or decay rate = 23%= 0.23

x = number of time intervals that have passed

since this problem is on the growth we are going to replace "b" with (1+r), likewise for decay (1-r)

hence the formula becomes

$y = a(1+r)^x.$

$f(x)=10000(1+0.23)^x \\\\f(x)=10000(1.23)^x$

The expression that will give the population value is

$f(x)=10000(1.23)^x$
