Answer:

Option A: $-\frac{4}{3}$ is the correct answer.

Step-by-step explanation:

Given that:

Slope of the line = $\frac{3}{4}$

Let,

m be the slope of the line perpendicular to the line with slope $\frac{3}{4}$

We know that,

The product of slopes of two perpendicular lines is equals to -1.

Therefore,

$\frac{3}{4}.m=-1\\$

Multiplying both sides by $\frac{4}{3}$

$\frac{4}{3}*\frac{3}{4}m=-1*\frac{4}{3}\\$

m = $-\frac{4}{3}$

$-\frac{4}{3}$ is the slope of the line perpendicular to the line having slope $\frac{3}{4}$

Hence,

Option A: $-\frac{4}{3}$ is the correct answer.

So I'm stuck on a math problem. Given z=3 + 5i and w= -5 +I, evaluate z-w

skad [1K]

Answer:

8 + 4i

Step-by-step explanation:

Put corresponding terms above each other and subtract in the usual way.

z = 3 + 5i

<u> w = -5 + i </u>

z - w = 8 + 4i: 3 - (-5} = 8; 5i - 1i = 4 i

Answer:

1. 600 x 20 x 20=240000

2. Jason should say "Find the product of 4 x 5 and then add all of the remaining zeroes in the problem to your answer. This results in 400,000 x 50,000= 20,000,000,000."

Solve the simultaneous equations 2x-y=7 3x+y=3

Debora [2.8K]

Answer:

<h2>( 2 , - 3 )</h2>

Step-by-step explanation:

Using elimination method:

2x - y = 7

3x + y = 3

--------------

5x = 10

Divide both sides of the equation by 5

$\frac{5x}{5} = \frac{10}{5}$

Calculate

$x = 2$

Now, substitute the given value of X in the equation

3x + y = 3

$3 \times 2 + y = 3$

Multiply the numbers

$6 + y = 3$

Move constant to R.H.S and change it's sign

$y = 3 - 6$

Calculate

$y = - 3$

The possible solution of this system is the ordered pair ( x , y )

<h3>( x , y ) = ( 2 , -3 )</h3>

---------------------------------------------------------------------

Check if the given ordered pair is the solution of the system of equation

$2 \times 2 - ( - 3) = 7$

$3 \times 2 - 3 = 3$

Simplify the equalities

$7 = 7$

$3 = 3$

Since all of the equalities are true, the ordered pair is the solution of the system

<h3> ( x , y ) = ( 2 , - 3 )</h3>

Hope this helps..

Best regards!!
