Answer:

None

See below under Remark.

Step-by-step explanation:

When you shift left, you think of moving in the negative direction. But it is not shown that way. You need to show what happens when you substitute a value in for x. Usually a graphing program helps to show which choice is right.

g(x) = f(x+4) = 2(x + 4)

None of the choices are this result, so we have to assume that the brackets were just omitted. The graph below shows what the answer given is the correct one.

Remark

Look at the graph carefully. The red line is f(x) = 2x

The blue line is g(x) = f(x-4) = 2(x - 4)

Notice that g(x) has shifted 4 units to the left. The x intercept has gone from 0,0 to (-4,0) and is so labeled.

If you have an answer with brackets around (x + 4) that's the one you choose. It needs the 2 outside the brackets.

A farmer sells 8.3 kg of apples and pears at the farmers market this way is apples and Restless Paris how many kilograms of Pari

Serga [27]

Answer:

She sell <u>2.075 kilograms</u> of pears at the farmer's market.

Step-by-step explanation:

<u><em>There is a mistake in the question some data is missing, so the correct question is below: </em></u>

<em>A farmer sells 8.3 kg of apples and pears at the farmer's market. 3 /4 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?</em>

Now, to find the kilograms of pears.

Total weight of apples and pears = 8.3 kg.

Weight of apples = $\frac{3}{4}$ of 8.3 kg.

So, to get the weight of apples:

$\frac{3}{4} \times 8.3$

$=0.75\times 8.3$

$=6.225\ kg.$

Thus, the weight of apples = 6.225 kg.

Now, to get the weight of pears we subtract the weight of apples from the total weight of apples and pears:

$8.3-6.225\\\\=2.075\ kg.$

Therefore, she sell 2.075 kilograms of pears at the farmer's market.

How do you simplify this equation?

Troyanec [42]

4^3*4^-5= 4^-2 (add the exponents since the base is the same)
5^-4*5^1= 5^-3 (add the exponents since the base is the same)

Square both terms (double the exponents)
(4^-2)^2= 4^-4
(5^-3)2= 5^-6

Then take out negative exponents (x^-a= 1/x^a)
4^-4 /5^-6 = 5^6/4^4

Final answer: 5^6/4^4

If you want it in number form
5^6= 15625
4^4=256
15625/256= 61.035...
