Find the illegal values of b in the fraction

 Find The Illegal Values Of B In The Fraction

Answers

Answer 1

Answer:

[tex]b=4\text { or }b=-2[/tex]

Step-by-step explanation:  

We have been given a rational expression: [tex]\frac{2b^2+3b-10}{b^2-2b-8}[/tex] and we are asked to find the illegal values of b.

Illegal values of b will be those values, which will make our denominator 0.

To solve for illegal or excluded values of b, let us set our denominator equal to 0.

[tex]b^2-2b-8=0[/tex]

We will factor out our equation by splitting the middle term.

[tex]b^2-4b+2b-8=0[/tex]

[tex]b(b-4)+2(b-4)=0[/tex]

[tex](b-4)(b+2)=0[/tex]

[tex]b-4=0\text { or }b+2=0[/tex]

[tex]b=4\text { or }b=-2[/tex]

Therefore, [tex]b=4\text { or }b=-2[/tex] are illegal values of b in the given fraction.

Solve h + p = 4(k − 8) for k.

Answers

Answer:

[tex]\frac{h+p+32}{4}[/tex]

Step-by-step explanation:

distribute the parenthesis

h + p = 4k - 32 ( isolate 4k by adding 32 to both sides )

h + p + 32 = 4k ( divide both sides by 4 )

k = [tex]\frac{h+p+32}{4}[/tex]


expand the brackets, to get 4k-32

sp you have; h + p = 4k - 32

add 32 to both sides==     h + p + 32 = 4k

/4

k= (h + p+ 32)/4

Which of the following would earn the same amount of interest as a​ $600 principal with​ 2.5% interest for 6​ years?

Answers

Final answer:

To earn the same amount of simple interest as $600 with 2.5% interest over six years ($90), another investment combination that would yield the same interest amount is $1,000 at 3% interest for 3 years.

Explanation:

The student is asking which investment would earn the same amount of simple interest as a principal of $600 with 2.5% interest over 6 years. The formula for calculating simple interest is Interest = Principal  imes Rate  imes Time. For the given principal of $600 with 2.5% interest over 6 years, the interest earned would be:

Interest = $600  imes 0.025  imes 6

Interest = $90

To find another investment with the same interest earned, one must find a principal, rate, and time that satisfy the equation:

Interest Earned = New Principal  imes New Rate  imes New Time = $90

An example would be a principal of $1,000 with 3% interest for 3 years:

Interest Earned = $1,000  imes 0.03  imes 3

Interest Earned = $90

This indicates that both investments would earn the same amount of interest over their respective periods.

Write the expression 6a-2(a-1) in simplest form

Answers

Final answer:

To simplify the expression 6a - 2(a - 1), distribute the -2 across the terms inside the parentheses, and then combine like terms to get the simplest form, which is 4a + 2.

Explanation:

To simplify the expression 6a - 2(a - 1), you need to distribute the -2 across the terms inside the parentheses and then combine like terms. Here's the process step by step:

Distribute the -2 to both a and -1 inside the parentheses: -2 x a gives us -2a, and -2 x -1 gives us +2.Write out the new expression without parentheses: 6a - 2a + 2.Combine like terms by subtracting -2a from 6a, which results in 4a.Add the constant term 2 to get the final simplified expression: 4a + 2.

The simplest form of the expression is 4a + 2.

b) y−2=−2(x+2)
c) y−6=−2(x+2)
d) y−2=2(x+2)

Answers

Answer:

the answer is c

Step-by-step explanation:


Answer:

c) y−6=−2(x+2)

Step-by-step explanation:

The general point slope form equation is:

y - y1 = m*(x - x1)

where x and y are the variables, (x1, y1) is the coordinate of a point on the line and m is the slope of the line.

To calculate the slope of the line we need two points on the line (x1, y1) and (x2, y2) and the following equation:

m = (y2 - y1)/(x2- x1)

Coordinates of point A: (-2, 6)

Coordinates of point B: (2, -2)

Replacing into the equation:

m = (6 - (-2))/(-2 - 2)

m = 8/(-4)

m = -2

Replacing this value and coordinate of point A into the general point slope equation we get:

y - 6 = -2*(x - (-2))

y - 6 = -2*(x + 2)

Which value is the same as 2 tenths?

Answers

One fifth
1/5

.........
Final answer:

2 tenths is equal to 0.2 in decimal format. This is derived from its fraction format, 2/10, and its place value in the base-ten number system, which is a 'tenths' place.

Explanation:

In mathematics, the value that is equivalent to 2 tenths is 0.2. This is because when we say 'tenths', we are referring to a fractional or decimal value that has a denominator of ten in the context of fractions or one place after the decimal point.

Therefore, 2 tenths is essentially 2 divided by 10 which equals 0.2 in decimal format. We can further illustrate this using a base-ten number system. In this system, each place to the right of the decimal point represents a 'tenths' place value. Therefore, in the number 0.2, the digit '2' is in the 'tenths' place.

Dan wants to make 12 pancakes but what quantity of each ingredient should he use for 240g plain flour,2 eggs and 600ml milk?

Answers

Final answer:

To make 12 pancakes, Dan should use 20g of plain flour, 2 eggs, and 50ml of milk.

Explanation:

To determine the quantity of each ingredient needed to make 12 pancakes, we can use the ratio of ingredients given in the recipe:

240g plain flour : 2 eggs : 600ml milk

To find the quantity of plain flour needed for 12 pancakes, we can set up a proportion:

240g / x = 12 / 1

Cross multiplying, we get:

x = (240g * 1) / 12

x = 20g

Therefore, Dan should use 20g of plain flour for 12 pancakes. Similarly, he should use 2 eggs and 50ml of milk for 12 pancakes.

A storeowner orders 25 calculators that cost ​$48 each. The storeowner can sell each calculator for ​$60. The storeowner sold 22 calculators to customers. He had to return 3 calculators that were never sold and pay a ​$2 charge for each returned calculator​ (although the initial cost is​ refunded). What is the​ storeowner's profit?

Answers

25*48=1,200

So we start at -1,200

22*60=1,320

So currently we are at a profit of $120.

120-6=114


Total profit: $114

Final answer:

As per the given values, the storeowner's profit is $114.

Explanation:

Total number of calculators = 25

Cost of calculators = ​$48

The amount at which they can be sold = $60.

To calculate the storeowner's profit, we need to consider the total cost and total revenue.

First, calculate the total cost of the calculators:
25 calculators x $48 each
= $1200.Next, calculate the total revenue from the sale of the calculators:
22 calculators x $60 each
= $1320.Deduct the cost of the returned calculators:
3 calculators x $2 charge each
= $6.Finally, calculate the profit:
Total revenue - Total cost - Cost of returned calculators
= $1320 - $1200 - $6
= $114.

Julia is allowed to watch no more than 5 hours of telivison a week. So far this week, she has watched 1.5 hours. write and solve an inequality to show how many hours of teli she can watch this week. ( can u show your work along with it? )

Answers

Answer:

she can watch 3.5 hours this week.

Step-by-step explanation:

Julia is allowed to watch no more than 5 hours of television a week.

Let x be the number of hours she can watch per week

number of hours not more than 5 hours

so x<=5

She already watched 1.5 hours. so inequality becomes

x+ 1.5 <= 5

Now we solve for x

subtract 1.5 on both sides

x + 1.5 < = 5 - 1.5

x < = 3.5

So, she can watch 3.5 hours this week.

The answer is A. g(x).

Here's why:

f(x) = -x^4 - 2: This function is a downward-facing parabola (due to the negative coefficient of x^4) with a maximum y-value at its vertex. The vertex occurs at x = 0, and the maximum y-value is f(0) = -2.

g(x) = -3x^3 + 2: This function is a cubic function with a local maximum, but it does not have a global maximum. However, its maximum value is still greater than the maximum value of f(x).

Key points:

The maximum y-value of f(x) is limited to -2 because of the negative leading coefficient and the constant term of -2.

g(x) doesn't have a defined maximum y-value, but it can reach values greater than -2, making its maximum value larger than that of f(x).

Therefore, g(x) has the largest maximum y-value among the two functions.

A recipe calls for 40 ounces of meat.How many pounds of meat does the recipe require?

Answers

Answer: 40 ounces=2.5 pounds


Step-by-step explanation:

Since 1 pound=16 ounces. You have to see how many times 16 goes into 40, it goes in forty 2 times with 8 left over so that means we need  decimal, since 8 is half of 16 the answer is 2.5.


Final answer:

To convert 40 ounces of meat to pounds, divide by the unit equivalence of 16 ounces per pound, resulting in 2.5 pounds of meat needed for the recipe.

Explanation:

The student is asking how many pounds are equivalent to 40 ounces of meat. To find the answer, you will need to know the unit equivalence between ounces and pounds.

The unit equivalence is 1 pound = 16 ounces. Therefore, to convert ounces to pounds, you divide the number of ounces by the unit equivalence.

Converting 40 ounces to pounds:

Start with the given amount in ounces: 40 ounces.Use the unit equivalence: 1 pound = 16 ounces.Divide 40 ounces by 16 ounces per pound to find the number of pounds.

40 ounces ÷ 16 ounces/pound = 2.5 pounds

So, the recipe requires 2.5 pounds of meat.
