2. Nancy is saving $2 from her allowance every week. Marco
is saving $1 the first week, $2 the second week, $3 the third
week, and so on. At the end of 10 weeks, who will have
saved more money? How much more?

Answers

Answer 1

Answer:

Marco will have $35 more than Nancy.

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

Nancy just has linear savings of N=2w

Marco has the sum of an arithmetic sequence of the form M=w(w+1)/2 or (w^2+w)/2

After 10 weeks Nancy has 2(10)=$20

Marco has (100+10)/2=$55

So Marco saved 55-20=$35 more than Nancy after 10 weeks.

Taxis usually charge a fee on top of the per-mile charge. In this case, the taxi charges $3 as a set fee and $0.80 per mile traveled. The function y=0.8x+3 is used to represent the total cost of a ride.

Answers

Answer:

$12.3

Step-by-step explanation:

Given data

We are given that the function for the charge is expressed as

y=0.8x+3

Where y is the total cost for a ride

X is the distance of the ride

Say x= 12 miles

Hence the total cost of the ride is

Y= 0.8*12+3

Y= 9.6+3

Y= $12.3

Hence a 12 miles Distance will cost $12.3

C. ( 4, 17 )

Step-by-step explanation:

Function: y = 3x + 5

Using method of elimination

A. (2, –1)

x = 2, y = -1

-1 = 3 (2) + 5

-1 ≠ 11

This option is incorrect!

B. ( –3, –4)

x = -3, y = -4

-4 = 3 (-3) + 5

-4 = - 9 + 5

-4 = -4

This option is correct!

C. ( 4, 17 )

x = 4, y = 17

17 = 3 (4) + 5

17 = 12 + 5

17 = 17

This option is correct!

D. ( 3, 8 )

x = 3, y = 8

8 = 3 (3) + 5

In order to obtain the ratio between numbers, we divide by the largest common factor between both.

In this question, the numbers are;

36 : 90

Use completing the square to solve the equation x2 - 10x = -8.

x 2 - 10x + 25 = -8
x 2 - 10x - 25 = -33

Answers

Answer:

x^2 - 10x + 25 = 17

Step-by-step explanation:

x^2 - 10x = - 8

Now x^2 - 10x = (x - 5)^2 - 25, so

(x - 5)^2 - 25 = -8

(x - 5)^2 = -8 + 25

x^2 - 10x + 25 = 17..

Solve these simultaneous equations:

3. 5x – 3y = 15 4x 3y = 6

2x + 5y = 26 4x + 3y = 24

3x + 3y = 39 2x - 3y = - 2

Answers

Answer:

1) We have the system:

5*x - 3*y = 15

4*x + 3*y = 6

To solve this, we first need to isolate one of the variables in one of the equations, let's isolate x in the first equation:

x = 15/5 + (3/5)*y = 3 + (3/5)*y

Now we can replace this in the other equation to get:

4*( 3 + (3/5)*y) + 3*y = 6

and solve this for y.

12 + (12/5)*y  + 3*y = 6

(12/5 + 3)*y = 6 - 12 = -6

(12/5 + 15/5)*y = -6

(27/5)*y = -6

y = -6*(5/27) = 1.11

Now we can replace this in the equation:

x = 3 + (3/5)*y

To get the value of x.

x = 3 + (3/5)*1.11 = 3.67

Then the solution of this system is the point (3.67, 1.11)

2) Now we have the system:

2*x + 5*y = 26

4*x + 3*y = 24

The solution method is the same as before:

x = 26/2 - (5/2)*y = 13 - (5/2)*y

Now we replace this in the other equation:

4*( 13 - (5/2)*y) + 3*y = 24

52 - 10*y + 3*y = 24

52 - 7*y = 24

52 - 24 = 7*y

28 = 7*y

28/7 = y

4 = y

now we replace this in the equatio:

x = 13 - (5/2)*y

x = 13 - (5/2)*4 = 13 - 10 = 3

The solution of this sytem is (3, 4)

3) Now we have the system:

3*x + 3*y = 39

2*x - 3*y = -2

first we isolate x in the first equation:

x = 39/3 - 3*y/3 = 13 - y

Now we can replace this in the other equation:

2*(13 - y) - 3*y = -2

26 - 2*y - 3*y = -2

26 - 5*y = -2

26 + 2 = 5*y

28 = 5*y

28/5 = y = 5.6

Now we can replace this in the equation:

x = 13 - y

To get the x-value

x = 13 - 5.6 = 7.4

Then the solution for this system is (7.4, 5.6)

Who can help me with these two?!? and can show work plz

Answers

Answer:

(4, 2 ) and (5, - 4 )

Step-by-step explanation:

(3)

6x + 2y = 28 → (1)

x = 2y → (2)

Substitute x = 2y into (1)

6(2y) + 2y = 28

12y + 2y = 28

14y = 28 ( divide both sides by 14 )

y = 2

Substitute y = 2 into (2) for corresponding value of x

x = 2(2) = 4

solution is (4, 2 )

(4)

x + y = 1 → (1)

2x + y = 6 → (2)

Rearrange (2) expressing y in terms of x by subtracting 2x from both sides

y = 6 - 2x → (3)

Substitute y = 6 - 2x into (1)

x + 6 - 2x = 1

- x + 6 = 1 ( subtract 6 from both sides )

- x = - 5 ( multiply both sides by - 1 )

x = 5

Substitute x = 5 into (3) for corresponding value of y

y = 6 - 2(5) = 6 - 10 = - 4

solution is (5, - 4 )

8) A (trapezoid) = 1/2(7)(10+12)
