In the xy- plane, the graph of the equation y + 3x + 5 is a line that intersects the y-axis at (0,b) what is the value of b?

maxonik [38]

Answer:

$b=5$

Step-by-step explanation:

The given equation is:

$y=3x+5$

To find the point where this line intersect the y-axis, we put x=0 into the given equation.

When x=0, we have $y=3(0)+5$ .

This implies that; y=5.

The y-intercept is (0,5).

Comparing (0,5) to (0,b), we can conclude that; b=5

How to solve 9x-(4x-1)=2

koban [17]

first, we can distribute the negative into the numbers in parentheses

9x-(4x-1)=2

9x-4x+1=2

now we can combine like terms and then isolate x

5x + 1 = 2

5x = 1

x = 1/5

Capital Value An investment produces a perpetual stream of income with a flow rate of

Elodia [21]

Answer:

$30,000

Step-by-step explanation:

The capital value is given by

$\int_{0}^{\infty} R(t) e^{-r t} dt$

where R(t) is annual rate

r - annual rate of interest

capital value $= \int_{0}^{\infty} 1200 e^{0.03t} e^{-0.07 t} dt$

= lim at b tend to infinity $\int_{0}^{b} 1200 e^{0.03t} dt$

=lim at b tend to infinity $\left [ \frac{1200}{-0.04} e^{-0.04 t} \right ]_0^b$

-30,000 { lim at b tend to inifinity $(e^{-0.04 b) = e^0]$

As $b\rightarrow \infty, e^{-0.04 b} \rightarrow 0$

$\int_{0}^{\infty} 1200 e^{0.03t} e^{-0.07 t} dt = -30,000(0 -1) =$30,000$
