Answer:

  1e. 2t² +8t -6

  2h. a² +2ab -3b²

  3b. 8r +4

  4b. 6x +4y -11

  5b. e -3

Step-by-step explanation:

1e. Combine like terms.

  (3t² +3t -6) +(-t² +5t) = t²(3 -1) +t(3 +5) -6

  = 2t² +8t -6

__

2h. (2a² +3ab -4b²) -(a² +ab -b²)

Use the distributive property to eliminate parentheses. Note that all signs change in the second set of parentheses.

  = 2a² +3ab -4b² -a² -ab +b² = a²(2 -1) +ab(3 -1) +b²(-4+1)

  = a² +2ab -3b²

__

3b. The hash marks indicate sides of the same length. The perimeter is the sum of all side lengths.

  P = (4r -2) +2(2r +3)

  P = 4r -2 +4r +6 . . . . . . eliminate parentheses

  P = 8r +4 . . . . . . . . . . . . combine like terms

__

4b. (3x +4y) +(5x -8) -(2x +3)

Note that the distributive property changes the sign of all terms in the last parentheses.

  = 3x +4y +5x -8 -2x -3 . . . . eliminate parentheses

  = x(3+5-2) +y(4) +(-8-3) . . . group like terms

  = 6x +4y -11

__

5b.

  Bill's age - Erin's age = (2e-3) -(e) = e -3

The difference in their ages is (e -3).

Answer:

(6, 5)

Step-by-step explanation:

midpoint ={ (8+4)/2, (7+3)/2}

(12/2, 10/2) = (6,5)

I'll do the first 6 rows to get you started.

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

In row 1, we have the number [tex]2^3[/tex] which is the same as writing 2^3

The base is 2 and the exponent is 3. Think of "base" as in "basement" to remember that the base is under the exponent. The exponent tells us how many copies of the base to multiply out. In this case, we have three copies of the base "2" multiplied to get 2*2*2 = 8

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

In row 2, we have the number 3^2. The base is 3 and the exponent is 2.

We can say 3^2 = 3*3 = 9. We have two copies of the base multiplied. Think of a 3 inch by 3 inch square that has area of 9 square inches.

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

Row 3:

The number 5^4 means 5^4 = 5*5*5*5 = (5*5)*(5*5) = 25*25 = 625

The base is 5 and the exponent 4 tells us how many copies of the base to multiply.

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

Row 4:

We aren't given the number like in the earlier rows. But we can see that the base is 6 and the exponent is 2. So the number to fill in that first blank is 6^2

The expanded notation would be 6*6 because the exponent tells us how many copies of the base to multiply out.

The standard notation is 36 because 6*6 = 36.

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

Row 5:

This time we don't have an exponent, but we have the base and we have the expanded notation.

The expanded notation of 8*8*8 means the base is 8 and the exponent is 3

So 8^3 = 8*8*8 = 512

We'll have 8^3 to fill in the first blank of row five, 3 fill in the next blank, and finally 512 fill in the last blank.

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

Row 6:

We have six copies of '9' multiplied together

This tells us we have the number 9^6. The base is 9 and the exponent is 6

Use your calculator to determine that 9^6 = 9*9*9*9*9*9 = 531441

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

I'll let you do the rest of the remaining rows.

Answer

The true least number of visits is the lowest whole number above 11.176470..., which is 12.

Step-by-step explanation:

points per visit, # of visits + sign-up points ≥ free tickets points

8.5 (points per visit)  

70 (# of visits)

165 (free ticket points)

8.5v ≥ 70 + 165

70 + 8.5v ≥ 165

8.5v ≥ 165 -70

8.5v/8.5v ≥ 95/8.5

v ≥ 11.1764705882

The true least number of visits is the lowest whole number above 11.176470..., which is 12.

Answer:

x = 15/2 or 7.5

Step-by-step explanation:

-4 (x - 1) + 6x = 2(17 - x)

First, distribute the -4 and 2, and remember that multiplying two negatives make a positive.

-4x + 4 + 6x = 34 - 2x

Combine like terms

2x + 4 = 34 - 2x

Subtract 4 from both sides

2x = 30 - 2x

Add 2x to both sides

4x = 30

Finally, divide both sides by 4

x = 15/2 or 7.5

Answer:

X=5

Step-by-step explanation:

3x+9 is twice of 12 (24). 24-9=15, and 3*5=15, so x=5.

Answer:

See explanation

Step-by-step explanation:

8x = 3y + 38  

24= 6y + 9x  

Rearrange;

3y - 8x = -38       * 2     -------(1)

6y + 9x = 24       * 1       -------(2)

6y - 16x = -76    -------(3)

6y + 9y  = 24    -------(4)

Subtract (4) from (3)

     -25y = -100

      y= 100/25

     y = 4

Substitute y =4 into(1)

3y - 8x = -38    

3(4) - 8x = -38

12 -8x = -38

-8x = -38 - 12

x = 50/8 = 6 2/8

2) 6 = 2x + y

7x = 3 - 3y

Rearrange;

2x + y = 6            * 3    --------(1)

7x + 3y = -3         * 1     --------(2)

6x + 3y = 18        ---------(3)

7x  + 3y = -3        ---------(4)

Subtract (4) from (3)

-x   = 21

x = -21

Substitute x = -21 into (1)

2x + y = 6

2(-21) + y = 6

-42 + y = 6

y = 6 + 42

y = 48

3)  

11x = 5 + 10y

7y = -2x +45

Rearrange

11x - 10y = 5          * 2  ---------(1)

2x + 7y   = 45       * 11  ---------(2)

22x - 20y = 10     --------(3)

22x + 77y = 495  --------(4)

Subtract (4) from (3)

       -97y  = -485

          y =  5

Substitute y =5 into (1)

11x - 10y = 5  

11x - 10(5) = 5

11x - 50 = 5

11x = 5 + 50

11x = 55

x = 55/11

x = 5

9514 1404 393

Answer:

Step-by-step explanation:

We can write the similarity statements by naming vertices in order of increasing numbers of arcs, starting with the one having a single arc. Then we can express the side lengths as a reduced ratio, in the same order.

1. JKLM ~ QRSP

  JK : KL : LM : MJ = 20 : 15 : 24 : 25

  QR : RS : SP : PQ = 12 : 9 : 14.4 : 15 = 20 : 15 : 24 : 25 (same ratios)

The scale factor is 12/20 = 0.6.

__

2. ΔABC ~ ΔUVT

  AB : BC : CA = 16 : 14 : 12 = 8 : 7 : 6

  UV : VT : TU = 24 : 21 : 18 = 8 : 7 : 6 (same ratios)

The scale factor is 24/16 = 1.5.

Answer:

4: “End Behavior”

Step-by-step explanation:

The end behavior of a function “f ” describes the behavior of the graph of the function at the “ends” if the x-axis.

In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞) and to the left end of the x-axis (as x approaches -∞).

Two decimals with a product close to 6.3 are, 2.5 and 2.52

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

To find Two decimals with a product close to 6.3.

Now, Let one decimal number is, 2.5

Hence, Second number is,

⇒ 6.3 / 2.5

⇒ 2.52

Hence, Two decimals with a product close to 6.3 are, 2.5 and 2.52
