Determine the equation of the line that passes through the points:

Mathematics
1 answer:
marin [14]3 years ago
3 0

Answer:

y = -2x+8

Step-by-step explanation:

First find the slope

m = ( y2-y1)/(x2-x1)

    = ( -4-4)/(6-2)

    = -8/4

   = -2

The slope is -2

We can use the slope intercept form

y = mx+b where m is the slope and b is the y intercept

y = -2x +b

Using the point ( 2,4)

4 = -2(2) +b

4 = -4+b

Add 4 to each side

4+4 = -4+4+b

8 = b

y = -2x+8

Surface area = 3 cm²

Find:

Thickens (Height)

Computation:

7/8 as a sum of fractions
Ratling [72]

(I am not sure if this is what you are looking for)

7/8 is seven eights, so we can break it into 7 parts.

\frac{1}{8} + \frac{1}{8} + \frac{1}{8} + \frac{1}{8} + \frac{1}{8} + \frac{1}{8} + \frac{1}{8} = \frac{7}{8}

Hope this helps, have a nice day!

Do you think maths classes tend to focus more on getting the right answer than understanding the process

Getting the right answer

Step-by-step explanation:

It really depends on what the teacher says but it's more important for you to understand the actual process, else you wouldn't be able to get the answers if you don't understand the process.

40 kg of tomatoes cost $200 how many kilograms of tomato’s can you get with $45
Roman55 [17]

Answer:

9 kg of tomatoes

Step-by-step explanation:

Cost of 40 kg of tomatoes = $200

Cost of 1 kg of tomatoes = 200/40 = $5

For $45, we get x kg of tomatoes,

kg       $

1          5

x         45

=> 45*1/5 = x kg (by cross multiplication)

=> 45/5 = x kg

We get 9 kg of tomatoes for $45.

Hope you understood!
