Answer:

f(x)=-3x+2

Step-by-step explanation:

The first one is a quadtratic function because it is in quadtratic form.

The second one is also not linear because it looks like a squiggly line. Sorry I forgot what they are called but I know it is not linear.

That leaves the last one is is linear and should be going down because there is a negative in front of the coefficient. It also has so exponent to prove why it is linear even further.

Hope this helps!

Answer: B

You can see that the length of the sides from abc are factored by 1/3 to get the length of xyz. Therefore, the scale factor is 1/3.

Answer:

[tex]\frac{99}{14}[/tex] or [tex]7\frac{1}{14}[/tex]

Step-by-step explanation:

[tex]5\frac{1}{2}[/tex] × [tex]1\frac{2}{7}[/tex]

Step 1. Convert the mixed fractions into an improper fraction (by multiplying the denominator by the whole number and adding the numerator with de denominator to the result)

Answer:

[tex]5\frac{1}{2}=[/tex] [tex]2[/tex] × [tex]5+1=[/tex] [tex]\frac{11}{2}[/tex]

[tex]1\frac{2}{7}=[/tex] [tex]7[/tex] × [tex]1+2=\frac{9}{7}[/tex]

Step 2. Multiply (by multiplying numerator by numerator and denominator by denominator)

Answer:

[tex]\frac{11}{2}[/tex] × [tex]\frac{9}{7}=\frac{99}{14}[/tex] or [tex]7\frac{1}{14}[/tex]

Answer:

The product of 5 1/2 and 1 2/7 is 7 1/14

Step-by-step explanation:

Turn the mixed numbers into improper fractions.

11/2 * 9/7

Multiply.

11/2 * 9/7 = 99/14

Turn into a mixed number.

99/14 = 7 1/14

Answer:

Step-by-step explanation:

369 = x + (x+2) + (x+4)

369 = 3x + 6

363 = 3x

121 = x

now that we know that x = 121, we can solve the equation by plugging in the variable

369 = x + (x+2) + (x+4)

369 = 121 + 123 + 125

369 = 369

The smallest three integers are 121,123 and 125.

Let, the smallest odd integers be n

Then according to the given condition,

[tex]n+(n+2)+(n+4)=369\\3n+6=369\\3n=363\\n=121[/tex]

So, the numbers are,

[tex]n=121\\n+2=121+2=123\\n+4=121+4=125[/tex]

Now in pot experiments the most important point is to have the same number of plants per pot. To achieve this you plant more seeds and then you thin them after emergence to keep the same number of uniform plant per pot.

Now for calculating fertilizer rate of application in pots, you calculate according to soil weigh as you correctly indicated 2.2 M Kg/ha. You don't have to weigh the soil, just use the bulk density to calculate weigh from volume. Forget about space in pot experiment. you will have a lot of problems since pots have different shapes and forms!

Another recommandation mix soil and fertilizers for each treatment for the number of replicate pots. If you are using 5 replicates pot of 2 Kg soil/ pot, mix the fertilizers you want to apply to the 5 pots with 10 Kg of soil and after mixing well (preferably mechanically) distribute the same volume of soil in each one of the 5 pots.

If the amount of fertilizer to apply is small mix with some soil first and mix well before mixing to the whole soil. The idea is to have as much as possible, a uniform distribution.

You might also consider fractionating you nitrogen source if it will be leached.

Now according to the exact aim of your work other method sof fertilizationare possible.

Finally remember that maize is a mycorrhizal plant and this beneficial symbiosis can be influenced by the amount of soluble P you are adding.

Answer:

 -12 b + 6 c + 18

Step-by-step explanation:

-4 b + 8 c + 12 - 8 b - 2 c + 6

After simplification, the correct value is,

⇒ 6 (- 2b + c + 3)

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We haver to given that;

The expression is,

⇒ -4b + 8c + 12 - 8b - 2c + 6.

Now, We can simplify by combine like terms as;

⇒ -4b + 8c + 12 - 8b - 2c + 6.

⇒ - 12b + 6c + 18

And, GCD of 12, 6, 18 = 6

Hence, Take 6 as common as;

⇒ - 12b + 6c + 18

⇒ - 2×6b + 6c + 3×6

⇒ 6 (- 2b + c + 3)

Therefore, The solution of the expression is,

⇒ 6 (- 2b + c + 3)
