Answer:

x=12

Step-by-step explanation:

3(x-1)=2x+9 - Original equation

3x-3=2x+9 - Distribute 3 through the parentheses

3x-2x-3=9 - Move variable to the left-hand side and change sign

3x-2x=9+3 - Move constant to the right-hand side and change its sign

x=9+3 - Collect like terms and add

x=12 - Answer

Hope this helps

On a coordinate plane, a dashed straight line has a negative slope and goes through (0, 3) and (2, negative 1). Everything to th

Nimfa-mama [501]

Answer:

The answer to your question is y < -2x + 3

Step-by-step explanation:

See the graph below

Process

1.- Find the slope

$m = \frac{y2 - y1}{x2 - x1}$

Substitution

$m = \frac{-1 - 3}{2 - 0}$

$m = \frac{-4}{2}$

$m = -2$

2.- Find the equation of the line

y - y1 = m(x - x1)

Substitution

y - 3 = -2(x - 0)

Simplify and solve for y

y - 3 = -2x

y = -2x + 3

3.- Write the inequality

As the left area of the plane is shaded the inequality must be

y < -2x + 3

The value of a mountain bike Y(in dollars) can be approximated by the model Y=200(1-.0025) to the t power, where T is the number

tino4ka555 [31]

Answer:

It will take 554 years

Step-by-step explanation:

Here, we want to estimate the time when t will be $50

We can rewrite the exponential equation as;

y = 200(1-0.0025)^t

In this case, y = $50 and we want to calculate t

so, we simply proceed to substitute the value 50 for y

we have this as ;

50 = 200(1-0.0025)^t

50/200 = (1-0.0025)^t

1/4 = 0.9975^t

0.25 = 0.9975^t

Take the natural logarithm of both sides

ln 0.25 = ln 0.9975^t

ln 0.25 = t ln 0.9975

t = ln 0.25 / ln 0.9975

t = 553.8 = 554 years

The bike will be $50 in 554 years
