Why are both 6 and -6 solutions to the equation below? x² = 36

Mathematics
1 answer:
elena55 [62]3 years ago
5 0

Answer:

6 and -6 are solutions because any negative multiplied by a negative is a positive. The negatives cancel each other out but this only works for multiplication from what I know.

Step-by-step explanation:

6 x 6 = 36

-6 x -6 = 36

Tom spent 1/6 of the day working in the flower bed. Tom spent 2/3 of that time adding mulch to the flower bed. What fraction of
maxonik [38]
Since 1/6 of the day was spent in the flower bed and 2/3 of that was spreading mulch, we need to find 2/3 of 1/6 to find out how much of the day was spreading the mulch.

In math "of" means times
"is" means equals

2/3 of 1/6 is
 
translates to

2/3 x 1/6 =

Now we just multiply the numerators across and denominators across then reduce if possible...

2/3 x 1/6 = 2/18

2 and 18 both divide by 2 so it reduces

2/18 = 1/9

Tom spent 1/9 of the day spreading mulch.

Experimental data are collected as:
aliina [53]

Answer:

y = 1.00114x + 1.75243

Step-by-step explanation:

Given

The x and y values

Required

The regression line equation

Because of the length of the given data, I will run the analysis using online tools, then analyze the result.

From the analysis, we have:

\sum x = 5050

\sum y = 5231.1011

\bar x = 50.5

\bar y = 52.311

SSX = 83325 --- Sum of squares

SP = 83419.7626 --- Sum of products

The regression equation is calculated as:

y = ax + b

Where:

a = \frac{SP}{SSX}

So, we have:

a = \frac{83419.76}{83325}

a = 1.00114

b = \bar y - a * \bar x

b = 52.31 - (1.00114*50.5)

b = 1.75243

So:

y = ax + b becomes

y = 1.00114x + 1.75243
