The points on the number line are -6 and 2.

2 - -6 = 4

2 + 6 = 4

A is not the answer.

--6 - 2 = 8

+6 - 2 = 4

B may be the answer.

-6 - 2 = -8

C is not the answer.

-2 - -6 = 4

-2 + 6 = 4

D is not the answer.

<h3>The answer is B) The value of -a - 6 is positive.</h3>

Let me know if this is the correct answer. :)

Given f(x) and g(x) = f(x) + k, use the graph to determine the value of k.

alexdok [17]

Answer:

The value of k would be 4

Step-by-step explanation:

If f(x) is shifted vertically k unit upward then,

Transformed function is,

g(x) = f(x) + k,

Using the given graph,

line f(x) passes through (0, -3)

line g(x) passes through (0, 1)

Difference in y-coordinate = 1 - (-3) = 1 + 3 = 4

∵ y-coordinate represents the vertical shifting,

So, g(x) = f(x) + 4,

Hence, the value of k would be 4.

Lucinda has a coin collection. she sold 12 coins to a friend and bought 7 new coins. she then had 39 coins. How many did she hav

erik [133]

Answer: 44

Step-by-step explanation:The way to calculate the number of coins that she had originally is to look at the difference in coins that changed hands. She sold 12 coins, but only bought 7 new ones. 12-7=5. Lucinda now has 5 coins less than what she started out with. So, she has 39 now, and then add 5 and the answer is 44 coins.

Part A: Find the LCM of 7 and 12. Show your work. (3 points)

inna [77]

Answer:

A. 84; B. 8; C. 8 × 19

Step-by-step explanation:

Part A. Least common multiple

Step 1. List the prime factors of each.

7 = 7

12 = 2 × 2 × 3

Step 2: Multiply each factor the greatest number of times it occurs in either number.

7 has one 7; 12 has two 2s and one 3.

LCM = 7 × 2 × 2 × 3

LCM = 7 × 12

LCM = 84

Part B. Highest common factor

Find all the factors of 56 and 96.

Factors of 56: 1, 2, 4, 7, 8, 14, 28

Factors of 96: 1, 2, 4, 6, 8, 12, 16, 24, 32, 48

The highest factor that in both 56 and 96 is 8.

Part C. Factoring

56 + 96 = 8(7 + 12) = 8 × 19

The GCF is 8.

19 = 7 + 12 is the sum of two numbers that do not have a common factor.

100 points! Mhanifa please help. Look at the picture attached. I will mark brainliest!

natima [27]

Answer: BC = 54 <kjm=44

Step-by-step explanation:

1st 0ne-

if you look at it as 2 triangles with D being the shared side- I can determine that the angles are congruent (by SSA theorem)

6x=9x-27 (by corresponding parts of congruent Theorem)

-3x=-27

x=9

BC- 9(9)-27= 81-27=54

2nd one-

J bisects KJM

4x+6=3x+10

x=4

3(4)+10= 22

4(4)+6= 22

KJM= 22+22= 44
