Item 3
Jessica and Raphael are saving money for concert tickets. Each friend starts with an amount and also saves a specific amount each week.

Jessica came up with the following equation to show the total, y, she has saved at the end of each week, x.

y = 10x + 20



Raphael created a table to show the total he has saved at the end of each week.

Weeks 0 1 2 3 4 5 6 7 8
Amount saved 40 46 52 58 64 70 76 82 88


After saving for a certain number of weeks, Jessica and Raphael will have each saved the same amount of money. How much money will they have each saved then?

Compare the rate at which each friend saves money.

Select the correct answer from the drop-down menu to complete the statement.

The rate at which Jessica is adding to her savings each week is $
1,4,6,8,or 10
more than the rate at which Raphael is adding to his savings each week.

Answers

Answer 1

Answer:

part 1: Jessica saved 100, Raphael saved 88

part 2: The rate at which Jessica is adding to her savings each week is $4 more than the rate at which Raphael is adding to his savings each week.

Step-by-step explanation:

First figure out how much money Jessica saved at the end of week 8, compared to Raphael.

Use x =8

y = 10*8 + 20 = 100

For Raphael it is shown in the table as 88.

Next figure out the rate Raphael saves. We can find the slope usng (y2-y1) / (x2-x1).

Using the table lets use (0,40) and (1,46)

46-40 / 1-0 = 6/1 = 6

So Raphael saves $6 each week. This is $4 less than what Jessica saves each week since the slope for her equation is 10 or $10 each week.

please give thanks :)

Solve for x. 1/2x + 18 = 1/4x - 6

Answers

Answer:

x = -96

General Formulas and Concepts:

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

1/2x + 18 = 1/4x - 6

Step 2: Solve for x

Subtract 1/4x on both sides:                    1/4x + 18 = -6Subtract 18 on both sides:                       1/4x = -24Divide 1/4 on both sides:                          x = -96

A student solved z + (-0.72) = -2.5 for z using the
following steps.
Step 1: Z + (-0.72) + (-0.72) = -2.5+ (-0.72)
z = -2.5+ (-0.72)
Step 2:
Step 3:
z = -3.22
What was the student's error?

Answers

Answer:

Mistake in step1

Step-by-step explanation:

Given

z + (-0.72) = -2.5

Solving in steps

1. ⇒ z + (-0.72) - (-0.72) = -2.5 - (-0.72)2. ⇒ z = - (2.5 - 0.72)3. ⇒ z = - 1.78

The student's mistake was adding (-0.72) instead of - (-0.72) or 0.72

Answer:

To solve, you must use the inverse operation. In step 1, -0.72 should have been subtracted from both sides, not added. Otherwise, 0.72 should have been added to both sides, not -0.72.

David expressed the ratio of the number of books that he owns to the number of DVDs that he owns as 27:11. Which statement could be true based upon this relationship? David has 11 books and 27 DVDs. David has 11 DVDs and 27 books. David has 11 DVDs and 27 items total. David has 11 books and 27 items total.

Answers

Answer: David has 11 DVDs and 27 books.

Step-by-step explanation:

When numbers are put in ratio form they are meant to compare their relative sizes.

The first number will be the first item being compared to the other.

For instance, if you had 2 pens and 3 pencils, the ratio of your pens to your pencils will be;  2:3. The ratio of your pencils to your pens however is 3:2.

In the same vein, a ratio of books to DVDs of 27:11 means that David has 27 books and 11 DVDs.

Answer:

David has 11 DVDs and 27 books.

Can somebody help me with this question, please? I have no idea how to do this or find the answer. :/ How many ways are there to choose a number from the set {−96, −48, −42, −36, −18, −14, −6, 14} that is divisible by either 6 or 8?

Answers

Answer:

28 different ways

Step-by-step explanation:

This is a combination question. Combination has to do with selection.

Total number of element in the set = 8

Number divisible by 6 or 8 are {-98, -48, -42, -36, -18, -6}

Total number divisible by 6 or 8 is 6

The number of ways we can choose 6 items from 8 is expressed as;

8C6 = 8!/(8-6)!6!

8C6 = 8!/(2)!6!

8C6 = 8*7*6!/2!6!

8C6 = 8*7/2

8C6 = 56/2

8C6 = 28 ways

Hence there are 28 different ways

22=-2x+4(-4x-17)

solve for x pls​

Answers

Answer:

x=-5

Step-by-step explanation:

22=-2x+4(-4x-17)

We move all terms to the left:

22-(-2x+4(-4x-17))=0

 We calculate terms in parentheses: -(-2x+4(-4x-17)), so:

-2x+4(-4x-17)

We multiply parentheses

-2x-16x-68

We add all the numbers together, and all the variables

-18x-68

Back to the equation:

-(-18x-68)

We get rid of parentheses

18x+68+22=0

We add all the numbers together, and all the variables

18x+90=0

We move all terms containing x to the left, all other terms to the right

18x=-90

x=-90/18

x=-5

Answer:

Step-by-step explanation:

22 = -2x + 4(-4x - 17)

22 = -2x + 4*(-4x) - 4*17

22 = -2x - 16x  - 68     {Combine like terms}

22 =  -18x - 68            {Add 68 to both sides}

22 + 68 = -18x

90 = -18x           {Divide both sides by (-18)

90/-18 = x

x = -5

the vertices of parallelogram abcd are A(4,0,3), B(3,4,-2),C(-2,0,1). find the coodrdinates of fourth vertices

Answers

Given :

The vertices of parallelogram ABCD are A(4,0,3), B(3,4,-2),C(-2,0,1).

To Find :

The coordinates of fourth vertices.

Solution :

We know, the vertices are ABCD .

Let, point D is (x,y,z) .

Also, diagonals of a parallelogram bisect each other.

Let, point of intersection of daigonal is O.

Coordinates of O are :

[tex]O_x = \dfrac{4+(-2)}{2}= 1\\\\O_y = \dfrac{0+0}{2 } = 0 \\\\O_z = \dfrac{3+1}{2}= 2[/tex]

O(1,0,2)

Value of point O through BD.

[tex]O_x = \dfrac{3+x}{2}\\\\x=-1\\\\O_y = \dfrac{4+y}{2}\\\\y = -4\\\\O_z= \dfrac{-2+z}{2}\\\\z = 6[/tex]

Therefore, the fourth vertices is D( -1,-4,6 ).
