PLZ HELP FAST I NEED TO GET MY GRADE UP DON"T WANT TO DO SUMMER SCHOOL!!!!!!!!!!!!Evaluate n=2

8n+3n-7
-------------
6x2N-3(n-1)
Enter the answer in lowest terms.

Answers

Answer 1
Answer: 8n+3n-7

8x2=16

3x2=6

16+6-7

22-7=15

6x2=12

12x2=24-3=21+1=22

15/22=5/11
Answer 2
Answer: OK 8(2) + 3(2)-7= 16 + 6 - 7 = 22-7 = 15

Next one: 6 x 2(2) - 3(2-1) = 6x4 - 3(1) = 24 - 3 = 21
You used a Capital N I assume you meant n
? I did not see a number value for Big N . so the answers are 15 and 21.

Write 5^8 as a quotient of two exponential terms with the same base in four different ways. Use only positive exponents.

Answers

The correct answer for the question that is being presented above is this one: 

5^8 can be represented into two exponential terms as quotients.

5^8
= 5^12 / 5^4
= 5^9 / 5
= 5^10 / 5^2
= 5^15 / 5^ 7

How can u simplify 44/42?

Answers

\frac { 44 }{ 42 } \n \n =\frac { 2\cdot 22 }{ 2\cdot 21 } \n \n =\frac { 2 }{ 2 } \cdot \frac { 22 }{ 21 }

\n \n =1\cdot \frac { 22 }{ 21 } \n \n =\frac { 22 }{ 21 }
You can divide by 2, 44 divided by 2 is 22 and 42 divided by 2 is 21.

How do u find the scale factor of dilation

Answers

Answer:

Step-by-step explanation:

We need to understand what is dilation?

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.

• A dilation that creates a larger image is called an enlargement. and its scale factor is greater than 1

• A dilation that creates a smaller image is called a reduction.and its scale factor is smaller than 1

  • The scale factor is 1, the figure and the image are congruent.

To find the scale factor of dilation, we need to identify the coordinates of one point in the original shape and the coordinates of one point in the scaled shape. Then divide the x-coordinate of the scaled point by the x-coordinate of the original point.

For example:

  • A (1 ,1) in the original shape
  • A' (2, 2) scaled shape

=> the the scale factor of dilation = 2 / 1 = 2

Hope it can find you well

Answer:


Step-by-step explanation:

Starting with ΔABC, draw the dilation image of the triangle with a center at the origin and a scale factor of two. Notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). Dilation with scale factor 2, multiply by 2.

To find a scale factor between two similar figures, find two corresponding sides and write the ratio of the two sides. If you begin with the smaller figure, your scale factor will be less than one. If you begin with the larger figure, your scale factor will be greater than one.

Tickets to a museum cost $17 each. For a field trip, the museum offers a $4 discount on each ticket. How much will tickets for 32 students cost?

Answers

17-4=$13
So our tickets now cost $13
So multiply that by 32
13•32=$416
For this problem you sinply multiply 4 by 32.

4 x 32 = 128

Therefore it will cost $128 for a field trip with 32 students
