Mathematics
1 answer:
QveST [7]3 years ago
8 0

Answer:

option D

Step-by-step explanation:

Take the two through which the lines passes.

Let it be ( -5 , 0) and ( 0 , -3)

Step 1 : Find slope, m

     Slope,m = \frac{y_2 -y_1}{x_2 - x_1}

                  = \frac{-3-0}{0--5} = \frac{-3}{5}

Step 2 : Find the equation

      (y - y_ 1) = m( x - x_1)\\\\( y - 0) = \frac{-3}{5} (x --5) \\\\y = -\frac{3}{5}( x  + 5 ) \\\\y = -\frac{3}{5}x  - 3

Can someone please help me with these 2 problems. With work please & thank u
Triss [41]

Answer:

I'm not good with the type of math on 3, so I'm going to answer 4. (P.S I don't know the question you're asking, so I'm going to assume you want to know the area and perimeter of the shapes.

Step-by-step explanation:

To solve number 4 I added the width of the 2 triangles to give me the width of the rectangle, so then 2 times 9 is 18. Then for the triangles. The formula for triangles is base times height divided by 2. So we add the areas of all shapes and we get: 18+6+24=48m. So the area for number 4 is 48 meters.

(hope this was your question)

if (20,14) is an ordered pair of the inverse of f(x) which of the following is an ordered pair of the function f(x)
Strike441 [17]
<h3>(14, 20) is the ordered pair of the function f(x)</h3>

<em><u>Solution:</u></em>

Given that,

(20, 14) is an ordered pair of the inverse of f(x)

We have to find the ordered pair of the function f(x)

In an inverse funciton, the domain of f(x) becomes the range and range of f(x) becomes the domain

To find the ordered pair of the function f(x),  we swap the variables x and y

(y, x) of inverse of f(x) becomes (x, y) of f(x)

Therefore, (14, 20) is the ordered pair of the function f(x)

Which expression shows the first step in simplifying 2x – 3(x + 2y) – 5(y – 7x)?
artcher [175]

Answer: Option 3.


Step-by-step explanation:

1. To simplify the expression shown in the problem, the first step is to apply the Distributive property, this means that you must multiply the number that are outside of the parentheses by the numbers inside of them.

2. Then, you have that the first step is:

2x-3(x+2y)-5(y-7x)=2x-3x-6y-5y+35x

3. Therefore, you can conclude that the correct answer is the third option.
