Answer:
Part A: <u>Which point represents the origin? </u>
- The origin is the point with both zero coordinates: (0, 0)
Part B: <u>Starting from the origin, explain how to plot the following three points accurately (1,-1) (-1.1.25) (-2,3).</u>
Reference point is the origin for below.
- (1,-1) - go <u>right </u>by 1 unit and <u>down </u>by 1 unit, plot the point
- (-1.1.25)- go <u>left </u>by 1 unit and <u>up </u>by 1.25 or 1 and 1/4 units, plot the point
- (-2,3) - go <u>left </u>by 2 units and <u>up</u> by 3 units and plot the point
Answer:
100
Step-by-step explanation:
Answer:
-2/5
Step-by-step explanation:
(6 - 8) / (3 - (-2)) = -2 / (5) = -2/5
Answer: 30
Step-by-step explanation:
Example
x=y
x+z=y+z
If we subtract the same number from both sides of an equation, both sides will remain equal.
Example
x=y
x−z=y−z
If we divide both sides of an equation by the same number, both sides will remain equal.
Example
x=y
x÷z=y÷z
If we multiply both sides of an equation by the same number, both sides will remain equal.
x=y
x⋅z=y⋅z

Answer:
Add 3 times row 1 to row 2 to obtain the new matrix
Step-by-step explanation:
Attached below is the solution
To obtain the new matrix we will add 3 times Row 1 to row 2
![\left[\begin{array}{ccc}3&-1&-4\\-5&3&8\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%26-1%26-4%5C%5C-5%263%268%5C%5C%5Cend%7Barray%7D%5Cright%5D)
