Does 3 (x-1) = 2x + 9 have one solution, no solution, or infinite solutions?

Answers

Answer 1

Answer:

one solution

x = 12

Step-by-step explanation:

3 (x-1) = 2x + 9

3x - 3 = 2x + 9

x - 3 = 9

add 3 to each side:

x = 12

Answer 2

Step-by-step explanation:

3x-3=2x+9

3x-2x=9+3

x=12

only one solution

Option C: I and II

Step-by-step explanation:

When you look at the question, it says that BD and AE is correct. When looking at the options we have to find which ones include BD and AE.

A. "I only" This is incorrect because "I" is not the only answer with BD and AE.

B. "III only" This is also incorrect because "III" doesn't have AE.

C. "I and II" This is correct because both "I" and "II" have BD and AE.

D. "I and III" This is incorrect because it has only BD.

Answers

Answer:

p = 1

Step-by-step explanation:

4 - 5(p + 3/5) = -4

Find P

4 - 5(p + 3/5) = -4

4 - 5p -15/5 = -4

4 - 5p - 3 = -4

-5p + 1 = -4

-5p = -4 - 1

-5p = -5

p = -5/-5

p = 1

Check:

4 - 5(p + 3/5) = -4

4 - 5(1 + 3/5) = -4

4 - 5 - 15/5 = -4

4 - 5 - 3 = -4

4 - 8 = -4

-4 = -4

What is the total surface area??

Answers

Answer:

790 units^2

Step-by-step explanation:

Take the area of each side and add them all up. Remember each side is there twice.

Formula: SA = 2(15*5 + 15*16 + 5*16)

SA = 2(75 + 240 + 80)

SA = 2(395)

SA = 790

What is the distance between points S and U if S is 2, 1 and U is 6, 8

Round to the nearest tenth of a unit.

A. 3.3 units

B. 6.4 units

C. 8.1 units

D. 12.0 units

Answers

The distance formula is:

D = sqrt((x2-x1)^2 + (y2-y1)^2)

D= sqrt ((6-2)^2 + (8-1)^2)

D = sqrt(4^2 + 7^2)

D = sqrt( 16 + 49)

D = sqrt(65)

D = 8.06

Rounded to the beat tenth = 8.1 units.

The answer is C. 8.1 units

Answer:

Step-by-step explanation:

S has coordinates (2 , 1) and U has coordinates (6, 8) . Computing the SU vector gives us (4 , 7)

taking the distance formula : sqrt(4^2 +7^2)

= sqrt(65) = 8.1 which is answer C

Which function represents this sequence?

A.
f(n) = 4 ∙ 2n-1

B.
f(n) = 4n-1

C.
f(n) = 2 ∙ 4n-1

D.
f(n) = 2n-1

Answers

Answer: A. f(n) = 4 ∙ 2n-1

Step-by-step explanation:

because the 1st term is 4 according to your image, and then you will have to multiply that by its common difference and using your table, to get from 4 to 8 then 8 to 16 you would multiply by 2, and you would finally multiply that by n or known as the number of terms and 1 making the equation. f(n) = 4 ∙ 2n-1 I hope this is very helpful for everyone.
