Answer:

x = 1/5, y = 6

Step-by-step explanation:

5x + y = 7

y = 7 - 5x

Set equations equal to each other to eliminate y

7 - 5x = 20x + 2

7 = 25x + 2

5 = 25x

x = 1/5

y = 7 - 5(1/5)

y = 7 - 1

y = 6

Answer:

C. y = 10x + 25

Step-by-step explanation:

If John put $10 each week but we don't know how many weeks that he deposits $10, use x as the amount of weeks. x10.

There was already $25 in his savings account so we don't have to put an x next to the $25.

Answer:

a. 10 + 2.50x

b. 60

c. 100

Step-by-step explanation:

a. 10 + 2.50x

b. 10 + 2.50(20)

= 10 + 50

= 60

c. 260 = 10 + 2.50x

250 = 2.50x

250/2.50 = x

x = 100

Answer: 10 hours

Step-by-step explanation:

First and foremost, we should note that:

Speed = Distance / Time

Total destination = 610 miles

Loretta speed = 55 mph

Time to be used by Loretta = 4 hours

Loretta's distance = Speed × Time = 55 × 4 = 220 miles

The distance to be covered by her dad will then be:

= 610 - 220

= 390 miles

Her dad's average speed = 65 mph.

Time taken by her dad will be:

= 390 / 65

= 6 hours

The number of hours to be used by the family will then be:

Time taken by Loretta + Time taken by her dad

= 4 hours + 6 hours

= 10 hours

Answer:

63 books in each boxes

1 book left which need a box

Step-by-step explanation:

James has 568 books

He plans to put them into 9 boxes

Therefore the number of books n each boxes can be calculated as follows

= 568/9

63 remainder 1

Hence there would be 63 books in each boxes and 1 book would be left which need another box

Answer:

Step-by-step explanation:

This is a difference of squares.

√x^2 - √49  is the basic formula for factoring a difference of squares. The  idea is that the middle term has been cancelled out.

√x^2 = x

√49 = 7

(x - 7)(x + 7) is the way this factors.

(x - 7)(x + 7)

===========

(x + 7)

The (x +7) in the numerator cancels with the (x + 7) in the denominator.

The answer is (x - 7)

====================================================

She might have wanted you to do it like this.

(x + 7) || x^2  + 0x    - 49  || x     -   7

            x^2 + 7x  ........... Subtract

           ==========

                   -7x      - 49

                   -7x      - 49   ...... Subtract.

                   =============

                           0

Or she might have seen you do this

x^2 - 49          x^2        49

=======   =   ===    -   =====

x + 7                x             7

Every math teacher freaks when they see this. I hope I didn't put ideas in your head.

But if you got the answer by doing what I did, you got it right.  

Answer:

Plz Brain -list the answer  It takes effort tnx dear

Step-by-step explanation:

From given condition

equation of line is given as,

x*cos(α)+y*sin(α)=p

& as tanα= 5/12 so from Pythagoras theorem

sinα=  5/13

​cosα=  12/13

⇒12x+5y=39

p = 3, α = tan-1 (5/12) So, tan α = 5/12 sin α = 5/13 cos α = 12/13 The equation of the line in normal form is given by By using the formula, x cos α + y sin α = p Now, substitute the values, we get 12x/13 + 5y/13 = 3 12x + 5y = 39 ∴

Step-by-step explanation:

Since angles in the same segment are equal, Angle ABC (x) = Angle AOC.

Since Angles AOC and COD are supplementary, Angle AOC = 180° - 130° = 50°

Therefore x = 50°.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the function

Putting all the values of y=9, 6, 0, and -3 to complete the table

FOR y=9

putting y=9

switch sides

subtract 3 from both sides

Hence,

when y=9, x=4

FOR y=6

putting y=6

switch sides

subtract 3 from both sides

Hence,

when y=6, x=2

FOR y=0

putting y=0

switch sides

subtract 3 from both sides

Hence,

when y=0, x=-2

FOR y=-3

putting y=-3

switch sides

subtract 3 from both sides

Hence,

when y=-3, x=-4

Hence, the table becomes:

x                     y

9                    4

6                    2

0                    -2

-3                   -4

Answer:

Option 4 (4, 2, 3)

Step-by-step explanation:

Coordinances for a three-dimensional coordinate system are (x, y, z).

The letter labeling each axis is always on the positive side.

Therefore, all of the coordinances must be positive.

If you look at the x,y plane you can identify that the point is two over on the y axis and four over on the x.  You can use this same strategy on the z axis to get the coordinances (4, 2, 3).

Answer:

Step-by-step explanation:

The arithmetic sequence represented by the expression 3n+1 , where n represents the position of a term in the sequence is B.4,7,10,13,16,...

check:

A. 3,6,9,12,15,...

using the 4th term

first term, a = 3

4th term = 12

3n + 1

= 3(4) + 1

= 12 + 1

= 13

not applicable

B. 4,7,10,13,16,...

using the 4th term

first term, a = 4

4th term = 13

3n + 1

3(4) + 1

= 12 + 1

= 13

applicable

C. 4,5,6,7,8,...

using the 4th term

first term, a = 4

4th term = 7

3n + 1

= 3(4) + 1

= 12 + 1

= 13

not applicable

D. 3,4,5,6,7,...

using the 4th term

first term, a = 3

4th term = 6

3n + 1

= 3(4) + 1

= 12 + 1

= 13

not applicable

Therefore, arithmetic sequence represented by the expression 3n+1 , where n represents the position of a term in the sequence is B. 4, 7, 10, 13, 16,...
