Answer:

Yes.

Step-by-step explanation:

If a function has a counterpart with the numerator and denominator switched multiplied by -1, then it is perpendicular. Also, here's image proof.

(-3 - 5i )(-3 + 5i ) = -16 34 34 - 30
Virty [35]

You can use:

(a-b)(a+b)=a^2-b^2

We know:

i=\sqrt{-1}\to i^2=-1

Calculate:

(-3-5i)(-3+5i)=(-3)^2-(5i)^2=9-25i^2=9-25(-1)=9+25=34

Find the equation of a line passing through the point(-3,0) and (2,-3)​
Svetradugi [14.3K]

Answer <u>(assuming the question allows it to be written in slope-intercept form)</u>:

y = -\frac{3}{5} x-\frac{9}{5}

Step-by-step explanation:

1) First, find the slope of the equation. Use the slope formula m = \frac{y_2-y_1}{x_2-x_1}, substitute the given points' x and y values, and simplify:

m = \frac{(-3)-(0)}{(2)-(-3)} \\m  =\frac{-3-0}{2+3}\\m = -\frac{3}{5}

Thus, the slope is -\frac{3}{5}.

2) Now, use the point-slope formula y-y_1 = m (x-x_1) and substitute real values for m, x_1, and y_1.

Since m represents the slope, substitute -\frac{3}{5} in its place. Since x_1 and y_1 represent the x and y values of a point the line crosses, use the x and y values of any one of the given points to substitute into the formula. (Either one is fine. I chose (2,-3).) Then, isolate y to put it into slope-intercept form and find the answer:

y-(-3) = -\frac{3}{5} (x-(2))\\y + 3 = -\frac{3}{5} x + \frac{6}{5} \\y = -\frac{3}{5} x - \frac{9}{5}

5/6 multiplied by 1/5<br> Show you work please
lesya692 [45]

Answer:

The answer is 5/30

Step-by-step explanation:

The answer is 5/30 because when multiplying a fraction by a fraction you have to multiply the numerator by the numerator and the denominator by the denominator so if you multiply 5 by 1 you get 5 and when you multiply 6 by 5 you get 30 so the answer is 5/30

What is two times the sum of 6 and some number is 30. What would the number be.?
Dvinal [7]

Answer:

The variable "a number" stands for 9.

Step-by-step explanation:

Rewrite the problem as 2 * (6 + x) = 30

Divide 30 into 2. 30/2 = 15

That means that the variable that is added to 6 must make the number 15.

15 - 6 = 9

The variable x is 9 so the equation would be:

2 * (6 + 9) = 30
