Answer:

Step-by-step explanation:

When we use the distributive property for expanding polynomial products, we often use it in the form ...

  (a +b)c = ac +bc

Here, we have ...

  (a +b) = (x -1)   ⇒   a=x, b=-1

  c = (4x+2)

So, the proper application of the distributive property looks like ...

  (a +b)c = ac +bc

  (x -1)(4x +2) = x(4x+2) -1(4x+2) . . . . . different from the work shown

We must conclude ...

  The distributive property was not applied correctly in the first step.

What is the equation for a line that passes through the points (8,2) and (-7,2)
TiliK225 [7]

Answer:

y = 0x + 2

Step-by-step explanation:

Find the slope.

Slope = <u> y2 - y1</u>

              x2 - x1

Plug in the points.

Slope =    <u>2 - 2</u>         =   <u>0</u>

                -7 - 8            -15

Pick a point to plug into the y = mx + b formula

I picked (8,2)

Now plug in the point and slope.

(Your teacher might prefer you to use 0/-17, but it can be simplified to 0, so I'll just use that.)

Equation: (2) = 0(8) + b

                 2  = 0 + b

                 2 = b  (b = 2)

Now put your slope and the y-intercept into the equation, and it will be:

y = 0x + 2

It's a bit hard to show on keyboard, so I hope you understand.

Find the slope of the line passing through the points (-2, 5) and (-6, 7).
Vlad1618 [11]
The slope would be - 1/2 !!

you would number the x and y values of the coordinates.

( -2 , 5 ) ( -6 , 7 )
x1. y1. x2. y2

then do the formula that gives you the slope y2 - y1 / x2 - x1

this gives you:

7 - 5 / -6 - (-2) = 2/ -4 (simplify) -1/2

so this would give you m= -1/2

Answer this (picture attached)
oee [108]

Answer:

80

Step-by-step explanation:

The ratio of sweets between the people would be

Sushil:Alex:Peter or 3:2:5

In this case, Sushil has 24 sweets meaning that 3 was multiplied by 8 in order to get 24. This means that we have to multiply all the numbers by 8 and and them up.

24+(2x8)+(5x8)

=24+16+40

=80 sweets
