If we multiply a positive and a negative number, is the result positive or
negative?

Answer:

y = - 3x + 11

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{3}[/tex] x - 3 ← is in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3, then

y = - 3x + c ← is the partial equation

To find c substitute (3, 2) into the partial equation

2 = - 9 + c ⇒ c = 2 + 9 = 11

y = - 3x + 11 ← equation of perpendicular line

Answer:

[tex] \frac{144}{35} [/tex]

Step-by-step explanation:

[tex]3 - \frac{3}{7} \div \frac{5}{8} [/tex]

[tex] \frac{18}{7} \div \frac{5}{8} [/tex]

[tex] \frac{144}{ 35} [/tex]

Answer:

Slope = 8 Y-intecept = (0, 3)

Step-by-step explanation:

Slope-intercept form: y = mx + b

m = slope

b = y intercept value

y = 8x + 3

m = 8

y = 3

Answer:

No. The margin of error only includes sampling variability.

Step-by-step explanation:

The margin of error would be considered for the sampling error

In the case when some adults does not have telephones so it is called as error selection bias this is not a sampling error

The selection bias, unresponse bias and the response would be the examples of an error but it is not a sampling errors

So there is no margin of error as it only involved the variability in the sampling

Answer:

10

Step-by-step explanation:

i think its 10 maybe cuz if u see

the perimeter of a rectangular room is 52 feet. right?

then then height is 2 more than the width. what is the width of the room? so am I right copying the question? yes the question is right copied ok!

now see when u subtract 2 from 12 it gives u 10 and length i as 2 more than the width so maybe 10

Answer:

4 3/7 as an improper fraction is 31/7

Answer:

31/7

Step-by-step explanation:

4 3/7

4 x 7 = 28

28 + 3 = 31

31/7

Answer: 1/4

Step-by-step explanation:

A die has 6 figures which are 1, 2, 3, 4, 5 and 6. There are 3 even numbers which are 2, 4 and 6. A coin has 2 outcomes which are head or tail.

The probability of getting an even number is 3/6 = 1/2.

The probability of getting a head is 1/2.

Therefore, the probability of obtaining an even number and a head will be:

= 1/2 × 1/2

= 1/4

Answer:

4 < x < 36;  values that apply are 5, 16, 20, 35

Step-by-step explanation:

use triangle inequality theorem:

the sum of any two sides is greater than the third

16 + x > 20;   x > 4

16 + 20 > x;   x < 36  

Answer:

$6.72

Step-by-step explanation:

1.68 is 7% of 24, so there is a 7% tax.

96x.07= 6.72

Answer:  The sales tax would be 6.72

Step-by-step explanation: 24 is 1/4 of 96 so that means that you have to multiply the sales tax number by 4 and 1.68 x 4 = 6.72

Answer:

D) y =   -2

The equation of the perpendicular line to the given line is  y = -2

Step-by-step explanation:

Explanation:-

Given point (-3,-2)

In graph the equation of line  x = 8 ( parallel to y- axis )

                              1 x + o y - 8 =0

The equation of the perpendicular line to the given line  

                        b x - a y + k =0

                       o x - 1 y + k =0 ...(i)

The equation (i) is Paases through the point ( -3,-2)

                        0 ( -3) -1(-2) + k =0

                               2 + k =0

                                     k = -2

∴The equation of the perpendicular line to the given line  is

     put k = -2 in equation (i)    

                        o x - 1 y + k =0

                      - y +(-2) =0

                       - y = 2

                         y = -2

Final answer:-

∴The equation of the perpendicular line to the given line is  y =-2

Answer:

Over time, mathematicians have developed a set of rules called the order of operations to determine which operation to do first. The rules are: Multiply and divide from left to right. Add and subtract from left to right.

Step-by-step explanation:

Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. Continue to perform multiplication and division from left to right. Next, add and subtract from left to right.

Answer:

You got to give me an qestion with numbers but hears how you do it.

Answer:

26.7pounds

Step-by-step explanation:

Suppose that an individual has a body fat percentage of 15.9% in weighs 168 pounds

This is calculated as:

Pounds of his weight that is made up of fat is calculated as

Body fat percentage × Body weight in pounds

= 15.9% × 168 pounds

= 15.9/100 = 168 pounds

= 26.712 pounds

Approximately to the nearest tenth = 26.7 pounds
