3x+5y=16 is linear equation........
Answer:
$28
Step-by-step explanation:
Time = 4 hours
Charge = $7 / hour
Multiply those two numbers:
4 hour × $7 / hour = $28
Function f(time) = $7 × time
Hopefully this answer helps you :)
The statements are true about the residual plot and the equation for the line of best fit include:
- The equation for the line of best fit is not a good approximation for the data because the points have a curved pattern.
- The residual plot has the pattern of a curve.

What is Residual plot?</h3>
This shows the residuals on the vertical axis and the independent variable on the horizontal axis.
Since the plot has a curved pattern, the equation for the line of best fit is not a good approximation for the data as the result will be inaccurate.

Answer:
A) y² - 5y + 1
B) y² - 5y - 4
C) - 5y + 1
D) - 3y² - 4y - 6
Step-by-step explanation:
Let's call P the unkown polynomial and D the difference. In each case, the following must be true:
y² - 5y + 1 - P = D
<em>A)</em>
y² - 5y + 1 - P = 0
y² - 5y + 1 = P
<em>B)</em>
y² - 5y + 1 - P = 5
y² - 5y + 1 - 5 = P
y² - 5y - 4 = P
<em>C)</em>
y² - 5y + 1 - P = y²
y² - 5y + 1 - y² = P
- 5y + 1 = P
<em>D) </em>
y² - 5y + 1 - P = 4y² - y + 7
y² - 5y + 1 - 4y² + y - 7 = P
- 3y² - 4y - 6 = P
