Answer:

  see below

Step-by-step explanation:

Starting from the point-slope equation ...

  y -y1 = m(x -x1)

Solving for y gives ...

  y = mx +(y1 -m·x1)

So, the slope-intercept form equation is fairly easily found:

  y = mx +b . . . . where m = m, and b = y1-m·x1

This is the equation we have used for 'b' in the attached spreadsheet.

__

Of course, the formula for slope is ...

  m = (y2 -y1)/(x2 -x1)

This is the equation we have used for 'm' in the attached spreadsheet. For all problems, we have used the first point. (It doesn't matter which point you use if there are two of them.)

__

The second attachment is the Google Sheets spreadsheet saved in ODS format. Most spreadsheet programs should be able to open that so you can see the formulas, if you're interested. (The gray values of m are computed using the two points. The unshaded values of m are entered by hand.)

_____

I'll write a couple of equations in each group so you can see how the spreadsheet numbers relate:

  y = mx +b

1.  y = 2x -7

3.  y = 2/3x +4

8.  y = 1/3x -5

9.  y = -5/2x +4

Answers

Answer:

Step-by-step explanation:

To solve this problem, simply multiply 800 x 0.12.

    800 x 0.12 = 96

I hope this was helpful to you! If it was, please consider rating, pressing thanks, and marking my answer Brainliest. It would help a lot. Have a great day!

Answer:

[tex]\huge\boxed{\text{96 students}}[/tex]

Step-by-step explanation:

In order to find how many students stay back for Chess Club, we want to find 12% of 800.

To do this, we can set up a percentage proportion.

[tex]\frac{12}{100} = \frac{x}{800}[/tex]

We can now solve for x by cross multiplying.

[tex]800 \cdot 12 = 9600\\9600 \div 100 = 96[/tex]

So, 96 students attend Chess Club on Wednesdays.

Answer:

A & E

Step-by-step explanation:

First, multiply 40 by 100, giving you 4000. You then divide 4000 by 25, where you will get a quotient of 160. Now, this can be represented as 160% or 160/100 because a percentage is always out of 100.

A serving of bagel chips contains 20 grams of carbohydrates, 3 grams of fat, and 3 grams of protein. How many calories would be in the serving of chips?
1 gram of protein= 4 calories, 1 gram of carbs= 4 calories, 1 gram of fat= 9 calories.

Answers

Answer:

119 calories in a serving

Step-by-step explanation:

>>1 gram of carbs=4 cal

20 g of carbs times 4 calories per gram of carbs= 80 calories

>>1 gram of fat=9 calories

3 g of fat times 9 calories per gram of fat= 27 calories

>>1 gram of protein=4 calories

3 g of protein times 4 calories per gram of protein= 12 calories

<80+27+12=119 calories total in a serving of chips>

Josh bought 3 bottles of grape juice and 5 bottles of water for a total of $14.50. Mary bought 2 bottles
of grape juice and 3 bottles of water for a total of $9.00. How much does the grape juice cost and the water?

Answers

Answer:

Bottle of water = $2Bottle of grape juice = $1.50

Step-by-step explanation:

Grape juice = gWater = w

Equations:

3g + 5w = 14.502g + 3w = 9.00

Subtract the 3 times the second equation from the twice the first:

2*(3g + 5w) - 3(2g + 3w) = 2*14.50 - 3*9.006g + 10w - 6g - 9w = 29 - 27w = 2

Then, finding g:

3g  + 2*5= 14.503g = 14.50 - 103g = 4.5g = 1.50

the diagram shows a circle inside a square ABCDB AB = 20 cm. the radius of the circle is 9 cm. work out the area of the shaded region

Answers

Step-by-step explanation:

Area of the square = a²

= 20²

= 400cm²

Area of the circle = πr²

= 22/7 × 9²

= 22/7 × 81

= 254.57cm²

Area of the shaded region = Area of the square - Area of the circle

= 400cm² - 254.57cm²

= 145.43cm²

Jiro and Joey share a 30-ounce box of cereal. By the end of the week, Jiro has eaten 3/10 of the box, and Joey has eaten 3/5 of the box of cereal. How many ounces are left in the box?

Answers

Answer:

6 ounce of cereal

Step-by-step explanation:

Step one:

given that the box is 30 ounce of cereal.

for Jiro----who ate 3/10 of the 30 ounce

=3/10*30

=9 ounce

Jiro ate 9 ounce

step two:

for Joey----who ate 5/10 of the 30 ounce

=5/10*30

=15 ounce

Joey ate 15ounce

the total ounces that both of them ate is

=9+15

=24

therefore the ounce left

=30-24

=6 ounce of cereal

The left over is 6 ounce of cereal

Make & the subject of the
Formula
6x ta=5(x+t)

What is the answer please

Answers

Answer is x = 5t-a

6x+a = 5(x+t) Expand the bracket
6x+a = 5x+5t Subtract the least x’s (so 5x)
x+a = 5t Subtract a to make x the subject
x = 5t-a

Answer:

x  = 5t - a

Step-by-step explanation:

The problem deals with making a variable the subject of the formula in the expression.

 Given expression:

            6x + a = 5(x + t)

  We are to make x the subject of the formula in the expression

   

Solution:

           6x + a  = 5(x+t)

On the right hand side, expand the parentheses and distribute the term outside;

          6x + a  = 5x + 5t

   Bring the term desired to be the subject to one side by adding (-5x) to both sides;

     6x + (-5x) + a = 5x + (-5x) + 5t

           x + a  = 5t

  Now add (-a) to both sides

         x + a + (-a) = 5t + (-a)

          x  = 5t - a

Alexa took a test and lost 3 points for each of the 7 questions she got wrong. She earned an additional 5 points for answering a bonus question correctly. How many points did Alexa receive or lose overall?

Answers

Answer:

Alexa lost 16 points overall

Step-by-step explanation:

To determine whether Alexa had a net receipt or loss of points, we will fine the total points received or lost, and find the difference:

points lost:

3 point for each of the 7 questions she answered wrong

lost point = 3 × 7 - 21 points

Points received:

5 points for answering a bonus question

point received = 5 point

The points lost (21) is greater than the points received (5), hence, there was a net loss. The net loss is calculated as follows:

points lost - points received

= 21 - 5 = 16

∴ Alexa lost 16 points overall


Find a point-slope form for the line with slope 1/5 and passing through the point (-4,-9).

Answers

Answer:

y + 9 = [tex]\frac{1}{5}[/tex](x + 4)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = [tex]\frac{1}{5}[/tex] and (a, b) = (- 4, - 9) , thus

y - (- 9) = [tex]\frac{1}{5}[/tex](x - (- 4) ) , that is

y + 9 = [tex]\frac{1}{5}[/tex](x + 4)

The angles of a triangle are x,2x,3x. Find the value of x in degrees​

Answers

Answer: x = 30°
Sum of interior angles is 180°, and there are 6x’s. 180 divided by 6 is 30

Step-by-step explanation:

x +2x+3x=6x

since triangles are 180° in total. 6/180=30

so 30° is your answer.

Adult tickets to a musical cost $15 and children's tickets cost $8. A total of 725 tickets were sold which brought in a total of $8775.

How many of each type of ticket were sold?

State the equation used to solve, along with both answers.

Answers

Given:

Cost of adult's ticket = $15

Cost of  children's  ticket = $8

Total tickets = 725

Total sales = $8775

To find:

The number of each type of ticket were sold.

Solution:

Let x be the number of adult tickets and y be the number of children's ticket.

Total tickets : [tex]x+y=725[/tex]         ...(i)

Total sales : [tex]15x+18y=8775[/tex]           ...(ii)

Multiply equation (i) by 15.

[tex]15x+15y=10875[/tex]         ...(iii)

Subtract (iii) from (ii),

[tex]15x+18y-15x-15y=8775-10875[/tex]

[tex]3x=-2100[/tex]

[tex]x=-700[/tex]

Putting x=-700 in (i), we get

[tex]-700+y=725[/tex]

[tex]y=725+700[/tex]

[tex]y=1425[/tex]

Therefore, the number of adult tickets is -700 and number of child tickets is 1425.

Note: The number of tickets cannot be negative. So, there must be some error in the question.
