true or false. if there are two solutions to a system of linear equations then there are an infinite number of solutions.

Answer:

16 months

Step-by-step explanation:

let m = number of months

6000 = 3200 + 175m

2800 = 175m

m = 2800/175

m = 16

Answer:

16 months

Step-by-step explanation:

First I will subtract how much he has already paid.

6000 - 3200 = 2800.

Now to find how many months it will take to get a total of 2800 dollars we must divide.

[tex]2800 \div 175[/tex]

= 16

this means that an additional 16 months will be needed to reach the total of 6000 dollars.

Hope this helps! :)

Answer:

[tex]GH = 7\ meters[/tex]

Step-by-step explanation:

Given

[tex]GH = 7\ meters[/tex]

Required

Length of GH after two rotations

In transformations, when a point, shape, line or line segment is rotated; the orientation and location of the point, shape, line or line segment change.

However, the length of the point, shape, line or line segment remains the same.

This is to say that:

After line segment GH is rotated twice, its length will remain unchanged.

Hence:

[tex]GH = 7\ meters[/tex]

Answer:

24 pieces

Quotient: 2

Step-by-step explanation:

This is the answer because:

1) If you cut one candy bar into half three times, there will be 4 pieces.

2) Then, just multiply 6 and 4 together to know how many pieces there are together:

6 x 4 = 24

Therefore, the answer is 24 pieces.

3) In order to find the quotient, just divide 6 and 3:

6 ÷ 3 = 2

Therefore, the quotient is 2.

The price of the coat after a 40% increase in price will be $77.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

A store pays $55 for a coat. The store marks up the price by 40%. Then the marked price is calculated as,

P = $55 x (1 + 0.40)

P = $55 x 1.40

P = $77

The price of the coat after a 40% increase in price will be $77.

Answer:

y = 4x + 9, y = -3x - 5

y = 2x + 5, y = 5x + 11

and y= 3x + 7, y = -x - 1

I just did this on Plato/Edmentum xD

The system of equations that intersect at point A = (-2, 1) is:

y = 4x + 9

y = -3x - 5

y = 2x + 5

y = 5x + 11

y = 3x + 7

y = -x - 1

We have,

Let's substitute the coordinates (-2, 1) into each equation to find the correct system of equations:

y = 10x - 1

Substituting (-2, 1):

1 = 10(-2) - 1

1 = -20 - 1

1 = -21 (Not satisfied)

y = 4x + 9

Substituting (-2, 1):

1 = 4(-2) + 9

1 = -8 + 9

1 = 1 (Satisfied)

y = -3x - 5

Substituting (-2, 1):

1 = -3(-2) - 5

1 = 6 - 5

1 = 1 (Satisfied)

y = 2x + 5

Substituting (-2, 1):

1 = 2(-2) + 5

1 = -4 + 5

1 = 1 (Satisfied)

y = x - 1

Substituting (-2, 1):

1 = -2 - 1

1 = -3 (Not satisfied)

y = 5x + 11

Substituting (-2, 1):

1 = 5(-2) + 11

1 = -10 + 11

1 = 1 (Satisfied)

y = 3x + 7

Substituting (-2, 1):

1 = 3(-2) + 7

1 = -6 + 7

1 = 1 (Satisfied)

y = -x - 1

Substituting (-2, 1):

1 = -(-2) - 1

1 = 2 - 1

1 = 1 (Satisfied)

Thus,

The system of equations that intersect at point A = (-2, 1) is:

y = 4x + 9

y = -3x - 5

y = 2x + 5

y = 5x + 11

y = 3x + 7

y = -x - 1

Answer:

B.  $19

Step-by-step explanation:

Approximate prices:

1/4 lb ham = 0.25 * $6 = $1.50

1 1/2 lb turkey = 1.5 * $5 = $7.50

1 lb roast beef = $7

3/4 lb bologna = 0.75 * $4 = $3

Add the approximate individual prices:

$1.50 + $7.50 + $7 + $3 = $19

Answer:

a) Number of projects in the first year = 90

b) Earnings in the twelfth year = $116500

Total money earned in 12 years = $969000

Step-by-step explanation:

Given that:

Number of projects done in fourth year = 129

Number of projects done in tenth year = 207

There is a fixed increase every year.

a) To find:

Number of projects done in the first year.

This problem is nothing but a case of arithmetic progression.

Let the first term i.e. number of projects done in first year = [tex]a[/tex]

Given that:

[tex]a_4=129\\a_{10}=207[/tex]

Formula for [tex]n^{th}[/tex] term of an Arithmetic Progression is given as:

[tex]a_n=a+(n-1)d[/tex]

Where [tex]d[/tex] will represent the number of projects increased every year.

and [tex]n[/tex] is the year number.

[tex]a_4=129=a+(4-1)d \\\Rightarrow 129=a+3d .....(1)\\a_{10}=207=a+(10-1)d \\\Rightarrow 207=a+9d .....(2)[/tex]

Subtracting (2) from (1):

[tex]78 = 6d\\\Rightarrow d =13[/tex]

By equation (1):

[tex]129 =a+3\times 13\\\Rightarrow a =129-39\\\Rightarrow a =90[/tex]

Number of projects in the first year = 90

b)

Number of projects in the twelfth year =

[tex]a_{12} = a+11d\\\Rightarrow a_{12} = 90+11\times 13 =233[/tex]

Each project pays $500

Earnings in the twelfth year = 233 [tex]\times[/tex] 500 = $116500

Sum of an AP is given as:

[tex]S_n=\dfrac{n}{2}(2a+(n-1)d)\\\Rightarrow S_{12}=\dfrac{12}{2}(2\times 90+(12-1)\times 13)\\\Rightarrow S_{12}=6\times 323\\\Rightarrow S_{12}=1938[/tex]

It gives us the total number of projects done in 12 years = 1938

Total money earned in 12 years = 500 [tex]\times[/tex] 1938 = $969000

Answer:

4 is c; 5 is a

Step-by-step explanation:

Given points for 4: (7, 2), (11, 5)

Given info for 5: (-2, -8); slope of  3

point-slope formula: y2 - y1 = m(x2 - x1)

Plugging in points: 5 - 2 = m(11 - 7)

Now we solve for m.

3 = m4

Final step: divide both sides by 4

Answer: m = 3/4

Second equation!

Plug into point-slope formula: y + 8 = 3(x + 2)

Distributive property of equality to eliminate parentheses

y + 8 = 3x + 6

Get y by itself by subtracting 8 to both sides

y = 3x - 2

The unknown side lengths are

Large triangle 10

Medium triangle 2

Small triangle 12/5 or 2.4

Step-by-step explanation:

EFD to ABC is 0.4 or 2/5

EFD to GHI is 0.24 or 6/25

ABC to GHI is 0.6 or 6/10

The side length of c is  2.

The side length of d is 10.

The side length of e is 10.

The side length of h is  2.4.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Triangles ABC, EFD, and GHI are all similar.

The side lengths of the triangles all have the same units.

This means,

The ratio of the corresponding sides of the two triangles is the same.

Now,

ΔABC and ΔGHI

4/(12/5) = 4/h = c/ (6/5)

20/12 = 4/h = 5c/6

We will consider 20/12 = 4/h.

20/12 = 4/h

5/12 = 1/h

h = 12/5

h = 2.4

We will consider 20/12 = 5c/6

20/12 = 5c/6

4/2 = c

c = 2

Now,

ΔABC and ΔEFD

4/e = 4/d = c/5

4/e = 4/d = 2/5

Consider 4/e = 2/5

4/e = 2/5

2/e = 1/5

e = 10

Consider 4/d = 2/5

4/d = 2/5

2/d = 1/5

d = 10

Thus,

The side length are:

c = 2

d = 10

e = 10

h = 2.4
