Answer:

The model is shown in the attached picture. The solution is 10.

Step-by-step explanation:

There are two way of showing a model for 2×5

The tape diagram has 2 equal-sized parts of 5
The tape diagram has 5 equal-sized parts of 2

Both models give the same solution:

5+5=10
2+2+2+2+2=10

In the attached picture we can show two types of diagram.

The graph models function R. The table of values models function S. Which statement is true about these functions?

Answer: OPTION D.

Step-by-step explanation:

The rate of change of a linear function is also known as "Slope".

The slope can be calculated with the following formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Choose two points on the function "R" graphed:

$(1,0)\\(0,-3)$

You can say that:

$y_2=-3\\y_1=0\\\\x_2=0\\x_1=1$

Substituting values into the formula, you get:

$m=\frac{-3-0}{0-1}=3$

Choose two point from the table that models the function "S":

$(4,21)\\(6,31)$

You can say that:

$y_2=31\\y_1=21\\\\x_2=6\\x_1=4$

Substituting values into the formula, you get:

$m=\frac{31-21}{6-4}=5$

Therefore, you can conclude that the function "S" has a greater rate of change than Function "R".

Solve the equation. 0=x+3

BabaBlast [244]

Here is your answer

0= x+3

Add -3 to both sides,

-3= x+3-3

-3= x

So,

x=-3

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.
