4-50:The graph at the right contains the lines for y=x+2 and y=2x-1
a.) Using the graph,what is the solution to this system?
b.) Solve the system algebraically to confirm your answer to part (a).

Answers

Answer 1

Answer:

a.) By using the graph, the solution to this system is (3, 5).

b.) Solving the system algebraically gives the same answer in part (a).

How to graphically solve this system of equations?

In order to graphically determine the solution for this system of linear equations on a coordinate plane, we would make use of an online graphing calculator to plot the given system of linear equations while taking note of the point of intersection;

y=x+2 ......equation 1.

y=2x-1 ......equation 2.

Part a.

Based on the graph shown, we can logically deduce that the solution for this system is represented by the ordered pair (3, 5) in quadrant I.

Part b.

By using the substitution method to substitute for y, we would set the two equations equal to one another;

x + 2 = 2x - 1

2x - x = 1 + 2

x = 3

y = x + 2

y = 3 + 2

y = 5.

Answer 2

Answer: x=3 and y=5. To solve the system algebraically, I think you just have to plug in the answers. I'm not quite sure for (b)

Describe how to model 2-digit by 2-digit multiplication using an area model ANSWER NOW FOR 20 POINTS

Answers

Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models. Properties of Multiplication and Division and Problem Solving with Units of 2–5 and 10. Multiplication and Division with Units of 0, 1, 6–9, and Multiples of 10Multi-Digit Whole Number and Decimal Fraction Operations.

Answer:

The steps are shown below:

Step-by-step explanation:

We can draw the area model for 2-digit by 2-digit multiplication by using the following steps:

Step 1: First write the multiplicands in expanded form.

For example: 26 as 20 and 6, and 36 as 30 and 6.

Step 2: Now, Draw a 2 × 2 grid, and write the terms of one of the multiplicands on the top of the grid. One on the top of each cell.

Step 3: Write the terms of the other multiplicand on the left of grid.

Step 4: Write the product of ones and tens in respective cell.

For example: 26×36

20 6

30| 600 180

6 | 120 36

Now add them: 600+180+120+36=936
