Answer:
b) (-3 + 5i)(1) = -3 + 5i
Step-by-step explanation:
First let's see what a multiplicative identity.
The <em>multiplicative identity property </em>states that any time you multiply a number by 1, the result is the original number.
Therefore, 1 is the multiplicative identity.
For instance, 3 * 1 = 3
Hence, according the property
(-3 + 5t)(1) = -3 + 5i states the multiplicative identity.
Hope you will understand the concept.
Thank you.
Answer:
Step-by-step explanation:
The scatter plot is a plot of amount spent on entertainment(in dollars) against the number of hours worked. The equation of the line of best fit is given as
y = 0.6x + 21.82
This equation gives the predicted amount spent on entertainment while the table gives the exact amount spent on entertainment.
1) when the number of hours worked is 7.8,
The observed amount is $33.50
The predicted amount is y = 0.6 × 7.8 + 21.82 = $26.5
The residual is 33.5 - 26.5 = $7
2) when the number of hours worked is 10.2,
The observed amount is $21.5
Approximately 22
The predicted amount is y = 0.6 × 10.2 + 21.82 = $27.94
Approximately $28
The residual is 22 - 28 = $6

1/3. 2/3
Answer:
Step-by-step explanation:
i believe this is multiplication so. just multiply 12 3/4 x 2/5. The answer to that would be 12 6/20. Now let's simplify. you can divide this fraction to the fraction 2/2. 12 6/20 divided by 2/2 equals to 12 3/4. I hope this right, and I really hope you get an A on your test.
If it's division than here's the steps. KCFM (keep, change, flip, multiply) keep 12 3/4, change the division symbol to multiplication, and flip the fraction 2/5 to 5/2. last step multiply. 12 15/8. If you can simplify that then simplify it. I don't see anyone to simplify it so your okay.
The answer is C (SAS)
Explanation:
AC = EC
BC = DC
angle ACB = angle DCE (Vertically Opposite Angles)
Therefore, the triangles are congruent by the Side-Angle-Side congruency
