evaluate f (x) = -4x + 7 when x = 2 and x = -2

Answer:

-13/6 or -2 and 1/6 or -2.16

Step-by-step explanation:

The solution of expression in mixed fraction form is,

⇒ 2 1/6

We have to simplify the expression,

⇒ 5 1/6 - 7 1/3

Firstly we can change it into improper fraction,

⇒ 5 1/6 - 7 1/3

⇒ 31/6 - 22/3

Make denominator same by taking LCM of 6 and 3 which is 6,

⇒ 31/6 - 44/6

⇒ (31 - 44) / 6

⇒ 13/6

⇒ 2 1/6

Therefore, The solution of expression in mixed fraction form is,

⇒ 2 1/6

Answer:

Change the confidence interval.

Step-by-step explanation:

The confidence interval should be altered . If a 95 % or 90% confidence interval is set then better results can be obtained for student satisfaction.

A 90 or 95  or 99 percent confidence interval will show  a greater range of the data that lies within or without the given criteria.

95 % confidence interval does not mean that the probability is 95% . It means that we are 95% of the data lies  or does not lie within the specific range.

This gives better results as compared to 60- 80 % confidence intervals.

If 95% of the students are satisfied as compared to 60% or 80% , this shows more accuracy.

Equation: y-5=8(x+4)

Step-by-step explanation:

Point-slope form is y-y1=m(x-x1)

Since m=8, y1=5, and x1=-4, then we have y-5=8(x+4) as our final equation

Step-by-step explanation:

Answer: $1004.4

Step-by-step explanation:

Simple math

The total commission of the employee will be $1004.4 for the given sale.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

4.5% of commission on sales.

Total selling = 36 x 620 = $22320

4.5% of $22320 = (4.5/100)22320 = $1004.4

Hence "The total commission of the employee will be $1004.4 for the given sale".

Solteros= 27

Step-by-step explanation:

Entiendo que de los 120 tripulantes, sobrevivió el 30%. Y de los sobrevivientes, 25% son casados.

Primero, debemos calcular la cantidad de sobrevivientes:

Sobrevivientes= 120*0.3= 36

Ahora la cantidad de casados, y por diferencia los solteros:

Casados= 36*0.25= 9

Solteros= 36 - 9

Solteros= 27

Answer:

from least to greatest or what? ill do lest to greatest tho

-7/8, -13/16, -1 4/5, 7/4

Step-by-step explanation:

all of these can be converted into a fraction with a denominator of 16 so you can compare easier except for -1 4/5 but that is the highest negative number so that would be the last one you put down because it has a whole number so it is greater than one therefor being greater than the rest of the negative fractions that are less than one, but for the rest, it is just simple least to greatest *(if it is greatest to least just reverse it)*

Answer:

From least to greatest: -1 4/5, -7/8, -13/16, 7/4

Greatest to least: 7/4, -13/16, -7/8, -1 4/5

Step-by-step explanation: Start with the greatest number. This would be 7/4 since it is the only positive number in the set of numbers. Then, find a common denominator for the rest of the numbers/fractions. To save time, a common denominator of -7/8, -1 4/5 and -13/16 is 80. Then, make all the equations equivalent. To do this, I’ll just use -13/16. So, just multiply 5 by 16 and -13 by 5 to get the right fraction. The answer would be -65/80 and you would do this process for the rest of the numbers. Once your done with this explanation, just remember that a lower negative number has a higher value on the number line making it greater in a set of numbers.

Answer:

C. 4

Step-by-step explanation:

The formula of slopes is: y2 - y1/x2 - x1

m = y2 - y1/x2 - x1

m = 15 - 7/5 - 3

m = 8/2

m = 4/1

m = 4

The slope of the line through the points (3,7) and (5,15) is  4 .

The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line.

Δy =  change in y coordinate  = y2 - y1

Δx = change in x coordinate = x2 - x1

m = Δy/Δx

where,

m is the slope  

According to the question

Points (3,7) and (5,15)

therefore,

(x1,y1) =  (3,7)

(x2,y2) =  (5,15)

Now ,

The slope of the line  

Using slope formula

m = Δy/Δx

Δy = y2 - y1  

Δy = 15 - 7

Δy = 8

Δx =  = x2 - x1

Δx = 5 - 3  

Δx = 2

Therefore,

m = [tex]\frac{8}{2}[/tex]

m = 4

Hence, the slope of the line through the points (3,7) and (5,15) is  4 .

Answer:

[tex]-\left(5.3x-7y\right)\left(-9.6\right)=\:50.88x-67.2y[/tex]

Step-by-step explanation:

Given the expression

[tex]-\left(5.3x-7y\right)\times \left(-9.6\right)[/tex]

[tex]=-\left(-9.6\right)\left(5.3x-7y\right)[/tex]

Apply distributive law

[tex]a\left(b-c\right)=ab-ac[/tex]

[tex]a=-\left(-9.6\right),\:b=5.3x,\:c=7y[/tex]

so the expression becomes

[tex]=-\left(-9.6\right)\times \:5.3x-\left(-\left(-9.6\right)\right)\times \:7y[/tex]

[tex]=-\left(-9.6\right)\times \:5.3x+7\left(-9.6\right)y[/tex]    ∵ [tex]-\left(-a\right)=a[/tex]

[tex]\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a[/tex]

[tex]=9.6\times \:5.3x-7\times \:9.6y[/tex]

[tex]=50.88x-7\times \:9.6y[/tex]

[tex]=50.88x-67.2y[/tex]

Therefore,

[tex]-\left(5.3x-7y\right)\left(-9.6\right)=\:50.88x-67.2y[/tex]
