A mother decides to teach her son about a letter each day of the week. She will choose a letter from the name of the day. For example, on Saturday she might teach about the letter S or the letter U, but not the letter M. What letters are possible to teach using this method? (There are 15.) List all the letters in alphabetical order, with no spaces

Answers

Answer 1
Answer:

Answer:

  • A, D, E, F, H, I, M, N, O, R, S, T, U, W, Y

Explanation:

Order the letters of each day, omitting the repetitions:

MONDAY:

  • A, D, M, N, O, Y

TUESDAY:

  • A, D, E, S, T, U, Y

WEDNESDAY:

  • A, D, E, N, S, W, Y

THURSDAY:

  • A, D, H, R, S, T, U, Y

FRIDAY:

  • A, D, F, I, R, Y

SATURDAY:

  • A, D, R, S, T, U, Y

SUNDAY:

  • A, D, N, S, U, Y

Put the letters together:

  • A, D, M, N, O, Y, A, D, E, S, T, U, Y, A, D, E, N, S, W, Y, A, D, H, R, S, T, U, Y, A, D, F, I, R, Y, A, D, R, S, T, U, Y, A, D, N, S, U, Y

Delete the repetitions:

  • A, D, M, N, O, Y, E, S, T, U, W, H, R, F, I.

Reorder:

  • A, D, E, F, H, I, M, N, O, R, S, T, U, W, Y ← answer

A line has the equation y = 6x + 13
What are the coordinates of the y-intercept of the line?

Answers

Answer:

(0,13)

Step-by-step explanation:

The equation y = 6x + 13 is in the slope - intercept form of y=mx + b, where m is the slope and b is the y-intercept.  The y-intercept (b) is the value of y when x = 0.  This means that the line will intersect the y axis at 13, when x is zero. =   (0,13)

↠ Answer :

(0,13)

↠ Step-by-step explanation :

We're given the following equation :

→ y = 6x + 13

Notice that this equation is in slope-intercept form (y = mx + b); here, m is the slope and b is the y-intercept.  So, the y-intercept is 13.

To find the coordinates, remember that a y-intercept has the form (0,b). The value of b is 13. So, the coordinates are (0,13).

Which set of ordered pairs (x, y) could represent a linear function?A = {(-6,3), (-3,0), (0, -3), (3,-5)}
B= Y(-1,2), (2, 1), (5,0), (8, -1)}
C = {(-4,-7), (-1, -3), (2.0), (5,3)}
D = {(-5, -8), (-2,-4), (1,1), (4,6)}

Answers

Set of ordered pairs (x, y) could represent a linear function

B= {(-1,2), (2, 1), (5,0), (8, -1)}

Option B is correct

Linear Function

Linear function is a function whose graph is a straight line .

Slope

Slope of a line tells us how steep the line is . Slope of a line is same at all the points.

Slope formula is (y_2-y_1)/(x_2-x_1)

Lets find out slope of any two points in each option

A = {(-6,3), (-3,0), (0, -3), (3,-5)}

(0-3)/(-3+6) =-1\n(-5+3)/(3-0) =-(2)/(3) \n

Slopes are not same

Lets check the second option

B={(-1,2), (2, 1), (5,0), (8, -1)}

(1-2)/(2+1) =(-1)/(3) \n(0-1)/(5-2) =(-1)/(3) \n(-1-0)/(8-5) =(-1)/(3) \n

The slope of any two points are equal .

slope are same . So it represents a linear function .

C = {(-4,-7), (-1, -3), (2.0), (5,3)}

slope =(-3+7)/(-1+4)=(4)/(3) \nslope =(0+3)/(2+1)=(3)/(3)=1

Slopes are not same . So it is not a linear function

D = {(-5, -8), (-2,-4), (1,1), (4,6)}

slope = (-4+8)/(-2+5)= (4)/(3) \nSlope = (1+4)/(1+2)= (5)/(3) \n\nslope = (6-1)/(4-1)= (5)/(3) \n

Slopes are not same . so it is not a linear function .

Option B is correct.

If 3 pounds of potato-salad feeds 15 people, how many pounds would you need for 200 people?

Answers

If 3 pounds of potato salad feeds 15 people, then 1 pound of potato salad would feed 5 people. Now divide 200 by 5 to get the number of pounds. 200/5 = 40 pounds

Randi and her distant sold ballons for .50 they made 48$ if Randy has twice as many balloons as your sister how many balloon animals did each girl make

Answers

Answer:Randy made 64 balloon animals and his sister made 32 balloon animals.

Step-by-step explanation:

Let x represent the number of balloon animals that Randi made.

Let y represent the number of balloon animals that her sister made.

Randi and her sister made balloon animals and sold the for. $0.50 each at the school carnival. They made $48.00. This means that

0.5x + 0.5y = 48 - - - - - - - - - -1

Randi made twice as many balloons as her sister. This means that

x = 2y

Substituting x = 2y into equation 1, it becomes

0.5 × 2y + 0.5y = 48

y + 0.5y = 48

1.5y = 48

y = 48/1.5 = 32

x = 2y = 2 × 32

x = 64
Randi has 32 balloons and the other girl has 16 simply divided 48/3
