For this case we must solve the following equation:

$-5x - 4 = 46$

To do this, we must clear the value of "x":

We add 4 to both sides of the equation:

$-5x - 4 + 4 = 46 + 4\\-5x = 50$

We divide between -5 on both sides of the equation:

$\frac {-5x} {- 5} = \frac {50} {- 5}\\x = -10$

Answer:

$x = -10$

-5x-4=46
-5x=46+4
-5x=50
÷both sides by -5x.
so your answer is going to be -10. and is so because u are diving with a negative number

The statement that best explains the effects of specializations in the US are:

The Midwest became a major grain-growing region of the United States. (Option B)
The north became dependent on workers who migrated from the South. (Option C)
The northeast became a center for manufacturing and industry. (Option F)

<h3>What is specialization in economics?</h3>

Specialization refers to the act of strategy of focusing on one's area of strength.

For a country, that would mean focusing on the production of goods and services in which it has a higher degree of advantage or efficiency.

Explain why Rolle's Theorem does not apply to the function even though there exist a and b such that f(a) = f(b).

aliya0001 [1]

This may help you

he functión Cot[x/2] is not continuos in the points <span>x=2nπ, where n=0,1,2,3,...</span> You can check it with a calculator. So the function is not continuos in the domain the problem gives you, so the Rolle's theorem can not be applied. If the inteverval was, <span>[π/2,3π/2]</span> Then we could apply the Rolle's theorem.

You have been tasked with filling 4 ounce and 3 ounce bags from a 41 ounce container of candy.

Alchen [17]

Answer:

A. 3 possible combinations

B. 8 4-ounce's bags and 3 3-ounce's bags

C. 2 4-ounce's bags and 11 3-ounce's bags

D. 8 4-ounce's bags and 3 3-ounce's bags

E. All solutions offer the same revenue.

Step-by-step explanation:

You have been tasked with filling 4 ounce and 3 ounce bags from a 41 ounce container of candy. Let x be the number of 4 ounce bags and y be the number of 3 ounce bags. Then

$4x+3y=41.$

A. Find all integer solutions:

When x=0, then 3y=41 - impossible, because 41 is not divisible by 3.

When x=1, then 3y=37 - impossible, because 37 is not divisible by 3.

When x=2, then 3y=33, y=11 - possible.

When x=3, then 3y=29 - impossible, because 29 is not divisible by 3.

When x=4, then 3y=25 - impossible, because 25 is not divisible by 3.

When x=5, then 3y=21, y=7 - possible.

When x=6, then 3y=17 - impossible, because 17 is not divisible by 3.

When x=7, then 3y=13 - impossible, because 13 is not divisible by 3.

When x=8, then 3y=9, y=3 - possible.

When x=9, then 3y=5 - impossible, because 5 is not divisible by 3.

When x=10, then 3y=1 - impossible, because 1 is not divisible by 3.

You get 3 possible combinations.

B. 1. 2 + 11 = 13,

2. 5 + 7 = 12,

3. 8 + 3 = 11.

The minimal number of bags is 11.

C. 1. 2·7+11·5=69 cents

2. 5·7+7·5=70 cents

3. 8·7+3·5=71 cents

The cheapest is 1st solution.

D. 1. 2·6+11·5=67 cents

2. 5·6+7·5=65 cents

3. 8·6+3·5=63 cents

The cheapest is 3rd solution.

E. 1. 2·2+11·1.50=$20.50

2. 5·2+7·1.50=$20.50

3. 8·2+3·1.50=$20.50

All solutions offer the same revenue.

Trae is searching for a treasure on the beach. From point $A$, he is told to walk two meters north, three meters east, and then

Nat2105 [25]

Answer:

Step-by-step explanation: In total, Trae walked 4 meters north and 3 meters east to get from point $A$ to point $B$. Since 3-4-5 is a Pythagorean triple, the length of $\overline{AB} = \boxed 5$.
