Write the equation in slope-intercept form, then find the slope and the y intercept. Finally draw the graph of the line. 9x+5y=2

Oksi-84 [34.3K]

Answer:

Check explanation.

Step-by-step explanation:

slope-intercept form: y=mx+b

9x+5y=23

5y=-9x+23

y=-9/5x+23/5

m=slope: -9/5

b=y-intercept: 23/5

The product of (3 2i) and a complex number is (17 7i) <br> What is the complex number.

lutik1710 [3]

(I'll assume that the blank spaces are PLUS signs ( + ),
as they usually are on Brainly.)

The mystery complex number is (5 - i) .

(3 + 2i) x (5 - i) = (17 + 7i)

FOIL it out and you'll see it.

Find the particular solution of the differential equation that satisfies the initial condition(s). f ''(x) = x−3/2, f '(4) = 1,

sweet [91]

Answer:

Hence, the particular solution of the differential equation is $y = \frac{1}{6} \cdot x^{3} - \frac{3}{4}\cdot x^{2} - x$ .

Step-by-step explanation:

This differential equation has separable variable and can be solved by integration. First derivative is now obtained:

$f'' = x - \frac{3}{2}$

$f' = \int {\left(x-\frac{3}{2}\right) } \, dx$

$f' = \int {x} \, dx -\frac{3}{2}\int \, dx$

$f' = \frac{1}{2}\cdot x^{2} - \frac{3}{2}\cdot x + C$ , where C is the integration constant.

The integration constant can be found by using the initial condition for the first derivative ( $f'(4) = 1$ ):

$1 = \frac{1}{2}\cdot 4^{2} - \frac{3}{2}\cdot (4) + C$

$C = 1 - \frac{1}{2}\cdot 4^{2} + \frac{3}{2}\cdot (4)$

$C = -1$

The first derivative is $y' = \frac{1}{2}\cdot x^{2}- \frac{3}{2}\cdot x - 1$ , and the particular solution is found by integrating one more time and using the initial condition ( $f(0) = 0$ ):
