For the pan one, you would colour all 4 of them (lightly) because she used all 4. For the cutting them up one, you did it right. For the next one, the first thing you need to do is colour 1 slice on the first triangle, on the 3rd on colour 2 slices, on the 2nd one colour two slices, and on the 4th one colour 4 slices. (Colour these ones hard.)

The 2nd pan could have 1/2 left, shade in 2, ( 2/4=1/2), and the 4th pan could also have 1/2 left, shade in 4, (1/2=4/8) and for the 1/3 ones you could the 1st one, shade 1,(1/3=1/3), and the 3rd pan, shade in 2, (2/6=1/3)

Write an equation in slope-intercept form: (1,6) and (2,3) are on the line
s344n2d4d5 [400]

Step-by-step explanation:

eqn of line : y = mx+ c

m = slope or gradient

c = y-intercept.

Lets take (1,6) = (x1,y1) and (2,3) = (x2,y2)

m \:  =  \frac{y1 - y2}{x1 - x2}  \\  =  \frac{6 - 3}{1 - 2}  \\ =  \frac{3}{ - 1}  \\  =  - 3

Substitute x = 1 and y = 6 into equation,

6 = ( - 3)(1) + c \\ 6 =  - 3 + c \\ c = 6 + 3 \\  = 9

Therefore substituting m and c value, equation of line is

y =  - 3x + 9

The difference between two number is 9 and the product of the number is 162 find the 2 number
erik [133]

Answer:

18 and 9

OR

-18 and -9

Step-by-step explanation:

Let:

first number = x

second number = y

According to given conditions:

x -  y = 9 ---------- eq1

x * y = 162 ------- eq2

From eq1:

x = 9 + y

Put it in eq2:

(9+ y)*y = 162

9y + y^2 - 162 = 0

OR

y^2 + 9y -162 = 0

By factorizing we get:

y^2 -9y + 18y - 162 = 0

Taking common:

y(y - 9) + 18(y - 9) = 0

(y - 9)(y + 18) = 0

So:

y = -18 and y = 9

ignoring negative integer

Putting values of y in eq1:

   x - 9 = 9

  x = 9 + 9

   x = 18

So the two numbers are:

18 and 9

OR

-18 and -9

i hope it will help you!
