Iodine test for starch

Method:

Place one spatula of the food sample on a dish or 1 cm3 if the sample is liquid.

Using a dropper, place a few drops of iodine solution onto the food.

Record any change in the colour of the solution.

Starch is detected using iodine solution. This turns blue-black in the presence of starch.

Answer/Step-by-step explanation:

First you would plot -9 on the number line

Then you would go to the right 5 times which would take you to -4 and that would be you answer.

(Sorry I could not find a number line to plot but I hope you get the idea)

Answer:

9x+3

Step-by-step explanation:

first you add common variables like 7x plus 2x and get 9x. since 3 does't have a common variable it is just 3 therefor you answer would be 9x+3

Starting : 7x+2x+3

combine like terms 7x+2x=9x

youre left with 9x+3

The equation for the line of best fit shows the relationship between the number of students enrolled

The equation for the line of best fit, then predict the number of students enrolled in 2011 is [tex]y = 90.2x - 177670.2[/tex]

To do this, we make use of a graphing calculator that has the following calculation summary

A regression equation is represented as:

[tex]y = bx + a[/tex]

So, we have:

[tex]y = 90.2x - 177670.2[/tex]

Hence, the regression equation is [tex]y = 90.2x - 177670.2[/tex]

Answer:

(0, -2) and (3, 1)

Step-by-step explanation:

y = x - 2, y = (x - 1)² - 3

To solve this problem, we need to find when the x and ys in both equations are equal.

So,

y = x - 2 = y = (x - 1)² - 3

x - 2 = (x - 1)² - 3

Simplify right side.

x - 2 = x² - 2x - 2

Subtract both sides by (x² - 2x - 2)

x - 2 - (x² - 2x - 2) = 0

Simplify.

-x² + 3x = 0

Factor x.

x (-x + 3) = 0

Because the only way to get a product of 0 is to multiply a number by 0, either x = 0 or (-x + 3) = 0 (x would be 3 in this equation)

So, x = 0 or x = 3

Now, to find y, plug x = 0 x = 3 into one of the equations.

When x = 3, y = x - 2 = 3 - 2 = 1

When x = 0, y = x - 2 = 0 - 2 = -2

Just in case, let's check these values.

Put x = 0 and y = -2 into y = (x - 1)² - 3

-2 = (0 - 1)² - 3 = (-1)² - 3 = 1 - 3 = -2

So, x = 0 and y = -2 is correct.

Put x = 3 and y = 1 into y = (x - 1)² - 3

1 = (3 - 1)² - 3 = 2² - 3 = 4 - 3 = 1

So, x = 3, y = 1 is correct.

Thus, the answers are

(0, -2) and (3, 1)
