the slope-intercept form of the equation for this line?

Answers

Answer:

u of the record for me and my family are doing well and that you have a meeting with the record for me and my family are doing well and that you have

Answer:

Step-by-step explanation:

Just rewrite  y-3 = {(x - 1) as   y-3 = m(x - 1).   {(x - 1)  is not valid.

Next, solve this y-3 = m(x - 1) for y:

Adding 3 to both sides yields    y = m(x - 1) + 3, or:

y = mx - m + 3, or

y = mx + (-m + 3).  This is in slope-intercept form.

If you choose m = 2, then the equation becomes

y = 2x +(-2 + 3), or:

y = 2x + 1

Note:  to get a single answer to this question you must provide the m value.

A packet of crisp weighs 32 grams to the nearest gram. a multi-pack crisp contains 10 packets. work out the least and the greatest weighs of the multipack. ignore the weight of the multipack

Answers

Answer:

Least weight of multipack :

31.5 * 10 = 315g

Highest weight of multipack :

32.4 * 10 = 324g

Step-by-step explanation:

Weight of a packet of crisp to the nearest gram = 32 g

The least value of the weight of actual packet = 31.5 (least number which can give 32 when rounded to the nearest gram)

The highest value of the weight of actual packet = 32.4g (Highest number which can give 32 when rounded to the nearest gram)

Since a multipack contains 10 packets of crisp :

Least weight of multipack :

31.5 * 10 = 315g

Highest weight of multipack :

32.4 * 10 = 324g

Answers

Answer:

width is 12.5 inches

Step-by-step explanation:

x is width, 3x is length,

Double each and make it equal to 100, ie. 2x+6x=100Divide everything by two, x+3x=50Combine x and 3x, 4x=50divide broth sides by 4x = 12.5Since x is width, width is 12.5Length is 3x, so 12.5 * 3 is 37.5

Rearrange and put the like terms on either side

25w - 7w - 2w = -18 - 3 + 25

16w = 4

Divide both sides by 16 to make the variable 'w' on its own

Rules of adding integers

To add integers having the same sign, keep the same sign. and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

Rules of subtracting integer

First, keep the first number (known as the minuend).  Second, change the operation from subtraction to addition.  Third, get the opposite sign of the second number (known as the subtrahend) . Finally, proceed with the regular addition of integers.

A random survey of quality of city parks is taken. Seventy-five percent of the people surveyed were pleased with the condition of the parks. If 180 people were please, the how many people were surveyed. (Hint: You can use a % bar or % proportion to solve)

Answers

Answer:

Number of people surveyed is 240 people

Step-by-step explanation:

We are told that Seventy-five percent of the people surveyed were pleased with the condition of the parks.

Now, if the number of people surveyed is represented by y, then number of people that were pleased with the condition of the parks = 75%y

This can be written as: 75y/100

Now, we are 180 people were pleased.

This means that;

75y/100 = 180

Let's multiply both sides by 100 to get;

(75y/100) × 100 = 180 × 100

This gives;. 75y = 18000

Divide both sides by 75 to get;

75y/75 = 18000/75

y = 240

Number of people surveyed is 240 people

The daily energy requirement for males is modeled by the chart below. Age (Years) (X) Energy Needed (Calories) (Y) 1 1100 2 1300 5 1800 8 2200 11 2500 14 2800 17 3000 Use the points (5, 1800) and (17, 3000) to determine a linear equation for the data.

Answers

Answer: y = 100x + 1300

Step-by-step explanation: Linear Equation is an equation whose graphic produces a line. It is of the form y = mx + B, in which m and B are real numbers.

The term m is also the slope or gradient of the equation, i.e., it shows the steepness of the line. While B is y-intercept, i.e., it is the point where the line touches the y-axis.

The slope is determined by:

[tex]m=\frac{y-y_{0}}{x-x_{0}}[/tex]

[tex]m=\frac{3000-1800}{17-5}[/tex]

m = 100

For the linear equation, use:

[tex]y-y_{1}=m(x-x_{1})[/tex]

and point (5,1800):

[tex]y-1800=100(x-5)[/tex]

[tex]y=100x-500+1800[/tex]

[tex]y=100x+1300[/tex]

The linear equation of daily energy requirement for males is [tex]y=100x+1300[/tex].

What is the equation of the line that passes through the point (-5, -3) and has a
slope of -1

Answers

Answer:

The equation of the line is y = - x - 8

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

m is the slope of the lineb is the y-intercept

Let us solve the question

∵ The slope of the line is -1

m = -1

→ Substitute it in the form of the equation above

∴ y = -1(x) + b

∴ y = - x + b

→ To find b substitute x and y in the equation by the coordinates of

   a point lies on the line

∵ The line passes through point (-5, -3)

∴ x = -5 and y = -3

∵ -3 = - (-5) + b

→ Remember (-)(-) = (+) and (-)(+) = (-)

∴ -3 = 5 + b

→ Subtract 5 from both sides

∴ -3 - 5 = 5 - 5 + b

-8 = b

→ Substitute it in the equation

∴ y = - x + (-8)

∴ y = - x - 8

The equation of the line is y = - x - 8
