To write a linear function with the given values f(3) = -4 and f(5) = -4, we can use the point-slope form of a linear equation. The linear function is y = -4.

To write a linear function with the given values f(3) = -4 and f(5) = -4, we can use the point-slope form of a linear equation. The formula for point-slope form is y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope. We can choose any point (x1, y1) from the given values. Let's choose (3, -4) as a point on the line. Now we can substitute the values into the formula to find the linear function:

y - (-4) = m(x - 3)

y + 4 = m(x - 3)

To find the slope, we can use another point on the line, such as (5, -4). Substituting the values into the formula, we get:

-4 + 4 = m(5 - 3)

0 = 2m

Solving for m, we get m = 0.

Now we can substitute the slope and one of the points back into the formula to find the linear function:

y + 4 = 0(x - 3)

y + 4 = 0

y = -4

So, the linear function with the given values is y = -4.

Given values f(3) = -4 and f(5) = -4 suggest a horizontal line as the y-coordinate remains constant at -4 regardless of x values. Hence, the linear function is f(x) = -4.

The student wants to know how to write a linear function with the values f(3)=-4 and f(5)=-4. The first thing we need to understand here is that a linear function is represented by the equation y = mx + b, where y is the output, m is the slope, x is the input, and b is the y-intercept. In this problem, since f(3) = -4 and f(5) = -4, it indicates that the y coordinate remains the same (-4), thus forming a horizontal line despite the changes in the x coordinates. This means the function has a slope (m) of 0. So, the linear function that satisfies these conditions is f(x) = -4.

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.

Gabe needs 20 liters of the 40% solution.  

He also needs 40 liters of the 70% solution.

Step-by-step explanation:

Equation:

acid + acid = acid

0.40x + 0.70(60-x) = 0.60*60

40x + 70*60 - 70x = 60*60

-30x = -10*60

x = 20 liters

Gabe needs 20 liters of the 40% solution.  

He also needs 40 liters of the 70% solution.

Answer: 30%

Step-by-step explanation:

The first step is to find the increase in numbers

26-20= 6

Now you find the percent. This means you're looking for the percent 6 is equal to when compared to 20. The easiest way is to divide the increase by the original number

6/20= 0.3

To convert that to percent, multiply it by 100

0.3 * 100= 30%

There was a 30% increase.

Final answer:

To calculate the percentage increase of guests from August's first party to the second, subtract the initial number from the final number, divide by the initial number, and multiply by 100. The calculation shows a 30% increase in guests from 20 to 26.

Explanation:

The question asks to calculate the percentage increase in the number of guests from the first dinner party to the second dinner party hosted by August. To find the percentage increase, you subtract the original number of guests from the new number of guests, divide by the original number, and then multiply by 100 to get the percentage.

We start with the initial number of guests at the first party, which is 20, and the final number of guests at the second party, which is 26. Using the formula:

Percentage Increase = ((Final Number - Initial Number) / Initial Number) × 100

Percentage Increase = ((26 - 20) / 20) × 100

Percentage Increase = (6 / 20) × 100

Percentage Increase = 0.3 × 100

Percentage Increase = 30%

Therefore, the percentage increase of the number of guests from the first party to the second party is 30%.

Answer:

11/20

Step-by-step explanation:

Answer:  [tex]\dfrac{11}{20}[/tex] represents the fraction of guests order the signature dish.

Step-by-step explanation:

Since we have given that

Percentage of guest who order the signature dish = 55%

Total percentage = 100

We need to find the fraction of guests order the signature dish.

So, Fraction of guests order the signature dish is given by

[tex]\dfrac{\text{Percentage of guest order the signature dish}}{\text{Total percentage}}\\\\=\dfrac{55}{100}\\\\=\dfrac{11}{20}[/tex]

Hence, [tex]\dfrac{11}{20}[/tex] represents the fraction of guests order the signature dish.

Answer:

Mr. Wright taught 1,050 students in 25 years.

Step-by-step explanation:

Given,

The number of students Mr. Wright taught = 18,

Also, every year the number of student is increased by 2,

So, in second year, the number of students = 18 + 2 = 20,

In third year = 20 + 2 = 22,

In fourth year = 22 + 2 = 24,

.............., so on,

Hence, we get an A.P. that shows the given situation,

18, 20, 22, 24, ............. till 25 years.....

First term, a = 18,

Common difference, d = 2,

And, number of terms, n = 25,

Hence, the total number of students that have been taught by him are,

[tex]S_n=\frac{n}{2}[2a+(n-1)d][/tex]

[tex]S_{25}=\frac{25}{2}[36+(25-1)2][/tex]

Answer:

Huma's share =Rs x =  Rs. 1.35392881

Seema's share =Rs. 12x =  Rs (12 *  1.35392881) = Rs. 16.2471457

Hubna's share =Rs. 123*12x =  Rs. (123*16.2471457) = Rs. 1998.39892

Step-by-step explanation:

Given :

Huma , Hubna and Seema received a total of ₨2,016 as monthly allowance from their mother.

Seema gets 12 of what Huma gets

Hubna gets 123 times Seema’s share

To find : How much money do the three sisters get individually?

Solution :

Let  Huma's share be Rs. x.

Since we are given that Seema gets 12 of  Huma's share

⇒ Seema's share = Rs 12x.

Since we are given that Hubna gets 123 times Seema’s share

⇒Hubna's share = Rs. (123 * 12x) = Rs. 1476x.

We are given that they received together Rs. 2016 in total .

⇒[tex]x+12x+1476x= 2016[/tex]

⇒[tex]1489x= 2016[/tex]

⇒[tex]x = \frac{2016}{1489}[/tex]

⇒[tex]x = 1.35392881[/tex]

Thus Huma's share =Rs x =  Rs. 1.35392881

Thus Seema's share =Rs. 12x =  Rs (12 *  1.35392881) = Rs. 16.2471457

Thus Hubna's share =Rs. 123*12x =  Rs. (123*16.2471457) = Rs. 1998.39892

Answer:

1.  B. BD

2. C. 15

3. A. 2

Step-by-step explanation:

1.  From the figure,

∠DAB = ∠DAC

Therefore, BD is the bisector of ∠ABC.

2.  From the figure, IG = GH

3x = 5x - 10

10 = 5x - 3x

2x = 10

x = 5

So, GH = 5x - 10

= 5(5) - 10

= 25 - 10

= 15

Therefore, GH = 15.

3.  From the figure,

∠DAB = ∠DAC

10y = 8y + 4

10y - 8y = 4

2y = 4

y = 2

The smallest diameter needed to drill through the wall is 0.75 inches, which is calculated by multiplying the inside diameter of the pipe (0.5 inches) by the ratio of the outside diameter to the inside diameter (1.5). Always measure and plan ahead to avoid mistakes.

The subject matter of this question is mathematics, specifically ratios. To find the smallest diameter you would need to drill into the wall, you would need to multiply the inside diameter of your pipe (0.5 inches) by the ratio of the outside diameter to the inside diameter (1.5). So, 0.5 inches * 1.5 = 0.75 inches.

This means, to allow the pipes to pass through the wall, you will need to drill a hole at least 0.75 inches in diameter. This is assuming the wall is thin enough that the entire length of the pipe that needs to pass through the wall is less than the thickness of the wall.

Remember, it's always better to pre-measure and plan ahead to avoid unnecessary work and potentially costly mistakes.

B. Total number of 6-ounce jars = 551

Total money earned from 6-ounce jars = $4408

Step-by-step explanation:

A. Jian's family's collection = 3311 ounces

Number of 4-ounce jars = [tex]\frac{3311}{4}[/tex]

= 827.75

Jian rounded it to 828 which is wrong. There are 827 jars that can be completely filled.

Cost per 4-ounce jar = $5.

Total cost = 827 × 5 = 4135

B. Now, number of 6-ounce jars =  [tex]\frac{3311}{6}[/tex]
