Mr. Hann is trying to decide how many new copies of a book to order for his students. Each book weighs 6 ounces .Which ordered pair is a viable solution if x represents the number of books he orders and y represents the total weight of the books, in ounces?

8×11/4+12

2×11+12

22+12

33

Answer:

{-1,7}

Step-by-step explanation:

1/2 | 5x-15| = 10

Multiply each side by 2

1/2 *2 | 5x-15| = 10*2

| 5x-15| = 20

Absolute value equations have two solutions, one positive and one negative

5x-15 = 20     5x-15 = -20

Add 15 to all sides

5x-15+15 = 20+15          5x-15 +15 = -20+15

5x= 35                                   5x=-5

Divide by 5

5x/5 = 35/5                              5x/5 = -5/5

x=7                                                   x=-1

The solution is,

ACDB = 3 cm²

AAMC = 6 cm²

AABD = 6 cm²

AADC = 3 cm²

AABC = 12 cm²

A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.

here, we have,

A median divides the area of a triangle into two equal parts. The first median, CM, divides triangle ABC into two equal areas, AMC and BMC. The second median, BD, divides triangle BMC into two equal areas, BMD and CDB.

We're given that ABMD = 3 cm², so ACDB is also 3 cm². The sum of those two areas is ABMC, which is also AAMC, 6 cm².

Median AD also divides ΔAMC in half, so AADC = 3 cm² and AADM = 3 cm². AABD is the sum of ABMD (3 cm²) and AADM (3 cm²) so is 6 cm².

AABC is the sum of the smaller areas, so is 12 cm².

Answer:

y = -2/3x + 2

have a good day :3

Step-by-step explanation:

we need to bring it into the form

y = ax + b

so,

2x + 3y = 6

3y = -2x + 6

y = (-2/3)x + 2

the slope is the factor of x (-2/3). the y-intercept is 2 (meaning y = 2 for x = 0).

Answer:

Option B. -4

Step-by-step explanation:

-12 x (1/3)

=> -12 ÷ 3

=> -4

Therefore, -4 is our answer.

Answer:

y=-9x-10

Step-by-step explanation:

First, start by putting the first equation into slope intercept form:

y=-9x+5

We know that in the standard slope intercept formula (y=mx+b), m is the slope and b is the y intercept. Thus, line with the same slope as the one above would have a slope of -9.

To have the same y intercept as y=-8x-10, the y intercept would have to be -10.

Therefore, the formula would be y=-9x-10

Answer:

y = - 6/5x + 8/9

Step-by-step explanation:

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

Where:

m: It is the slope of the line

b: It is the cut point with the y axis

We have the following equations:

Equation 1:

By definition, if two lines are perpendicular then the product of their slopes is -1:

Equation 2:

Finally, the requested equation is:

Answer:

  x = 12

  perimeter = 124

Step-by-step explanation:

The midline RS is half the length of MN, so we have ...

  2×RS = MN

  2(x +3) = 5x -30

  2x +6 = 5x -30

  36 = 3x . . . . . . . . . add 30-2x

  12 = x . . . . . . . . . . divide by 3

__

The length RS is then ...

  RS = x +3 = 15

and the perimeter of QRS is ...

  P(QRS) = QR +RS +SQ = 25 +15 +22 = 62

The perimeter of QRS is half the perimeter of MNP, so ...

  P(MNP) = 2×P(QRS) = 2×62 = 124

The perimeter of ΔMNP = 124.

Answer:

9

Step-by-step explanation:

9>6

ex. 92>69

nine is greater than 6, meaning that if a number begins with a 9, it automatically means that it is bigger than a number beginning with a 6.

The two-digit number formed with tens place taken by 9 will be always greater than the two-digit number formed with tens place taken by 6.

The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.

Let the two of the multi-digit number be a two digit number.

Now, It is known that the left-most place in a two-digit number is always tens place. Therefore, if a two-digit number is formed by the tens place taken by 6 and the unit digit taken by any other number, then it will always be less than the two digit number formed by formed by the tens place taken by 9 and the unit digit taken by any other number.

Also, if the two numbers are 4 digit numbers, the four-digit number is formed by the thousand place taken by 6 and the other place taken by any other digit, then it will always be less than the four digit number digit number formed by formed by the thousand place taken by 9 and the other place digit taken by any other digit.

Hence, the two-digit number formed with tens place taken by 9 will be always greater than the two-digit number formed with tens place taken by 6.

Answer : 2

Step-by-step explanation:

Slope is a ratio, Slope = rise/run. This can also be described as "the change in Y" / "The change in X"

So, using the table, find the rate of change in the y-values and the x-values.

y = mx + b

slope : m

x=-7, y=2 : -7m + b = 2 (1)

x=-6, y=4 : -6m + b = 4 (2)

(2)-(1) => m= 2

Answer:

0

Step-by-step explanation:

→ State the slope formula

( y₂ - y₁ ) ÷ ( x₂ - x₁ )

→ State each value

x₁ = 3, y₁ = 18, x₂ = 0 and y₂ = 18

→ Substitute in each value into the formula

( 18 - 18 ) ÷ ( 0 - 3 )

→ Simplify

:

Trying to factor by splitting the middle term

2.1     Factoring  4a2-2a+9

The first term is,  4a2  its coefficient is  4 .

The middle term is,  -2a  its coefficient is  -2 .

The last term, "the constant", is  +9

Step-1 : Multiply the coefficient of the first term by the constant   4 • 9 = 36

Step-2 : Find two factors of  36  whose sum equals the coefficient of the middle term, which is   -2 .

     -36    +    -1    =    -37

     -18    +    -2    =    -20

     -12    +    -3    =    -15

     -9    +    -4    =    -13

     -6    +    -6    =    -12

     -4    +    -9    =    -13

For tidiness, printing of 12 lines which failed to find two such factors, was suppressed

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Using the information given in the table, the number of weeks that would pass before more dogs would have to be washed is 16 weeks.

Given the Parameters :

Recall :

Profit made per week = $124 - $8 = $116

Total amount of profit made :

. Total profit made = $116 × 8 = $928

Total amount owned = $928 + $32 = $960

Number of weeks before total amount owned is expended can be calculated thus :

Number of weeks = ($960 ÷ $60) = 16

Hence, 16 weeks will pass before more dogs would have to be washed.

Answer: 3 and a half acres.

Explanation: 7 divided by 2 is 3 and a half acres.

Answer:

  A: 2 1/2 ft^2/h

  B: 3 1/3 ft^2/h

  B has the greater rate

Step-by-step explanation:

The rate in square feet per hour is found by dividing square feet by hours.

Machine A:

  (5/8 ft^2) ÷ (1/4 h) = (5/8)×(4/1) ft^2/h = 5/2 ft^2/h = 2 1/2 ft²/h

Machine B:

  (2/3 ft^2) ÷ (1/5 h) = (2/3)×(5/1) ft^2/h = 10/3 ft²/h = 3 1/3 ft²/h

Machine B has the greater rate.
