vovikov84 [41]3 years ago
5 0

Answer:

\large\boxed{m=-\dfrac{1}{2}}

Step-by-step explanation:

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

From the graph we have the points (2, 3) and (4, 2). Substitute:

m=\dfrac{2-3}{4-2}=\dfrac{-1}{2}=-\dfrac{1}{2}

Other method.

Look at the picture.

m=\dfrac{\Delta y}{\Delta x}

\Delta y=-1\\\\\Delta x=2

Substitute:

m=\dfrac{-1}{2}=-\dfrac{1}{2}

First, add the numbers in the hundredths column:

9+8=16

Carry the one, and add the numbers in the tenths column:

1+0+3=4

Now, add the numbers in the ones column:

1+1=2

Bring the decimal straight down.

The answer is 2.46

Hope this helps!!

4. Why do people sometimes use credit to pay for items instead of just using cash?
Makovka662 [10]

Answer:

Some people use credit to pay for items instead of just using cash so they do not have to carry money around and so it is easier. ... It is preferable to receive a low interest rate so you do not have to pay high amounts. Sometimes, lenders allow or require a down payment before they extend you the loan.

B, x = 2

Step-by-step explanation:

Given the vertices of the image, and preimage of this right isosceles triangle, we can find the line of reflection by definitively understanding how reflections work. Given the preimage contains the points A(-1,1), B(1,-1), and C(-3,-1). And that the image contains the points A'(5,1), B'(3,-1), C'(7,-1). We can differentiate the corresponding points and apply them to the rules of a reflection. if figure Z is reflected over x = n,

than Z'(x,y) = Z(-x+2n,y). Logically, you can see that this pattern resembles all three coordinates for the transformation. i.e A'(5,1) = A(--1+2n,1) ; (1+2n,1) = (5,1) ; 1 + 2n = 5, 2n = 4, n = 2

we can prove this by using another point:

B'(3,-1) = (-1+2n,-1) = (-1 + 4, -1) = (3,-1)

Hopefully you understand,
