Answer:
C) y is equal to 10.5x
Step-by-step explanation:
$31.50 is charged for <em>3 </em>hours so, for 1 hour we need to divide 31.50 by 3, which results in 10.50. So 1 hour of babysitting is $10.50
this is because x is equal to the number of hours they babysit. we do not know the actual so it is replaced with x
and y is equal to the sum of 10.5x because we multiply the number of hours worked, and the amount per hour.
The correct answer for the question that is being presented above is this one: "The reason for the difference can not be determined with the information that is given." Looking at the scatter plot of pages versus amazon price, it appears that the data might be clustered around two separate regression lines. The cause of the split in the data is that <span> the difference can not be determined with the information that is given</span>
The answer is very simple each had planted 37 flowers
Answer:
yes
Step-by-step explanation:
If 2 lines are perpendicular then the product of their slopes = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x - 4 ← is in slope- intercept form
with slope m = - 1
5x - 5y = 20 ( subtract 5x from both sides )
- 5y = - 5x + 20 ( divide all terms by - 5 )
y = x - 4 ← in slope- intercept form
with slope m = 1
Thus product of their slopes is - 1 × 1 = - 1
Therefore the lines are perpendicular
Answer:
x = 12, y = 0
Step-by-step explanation:
Use elimination.
24y = 0
y = 0
Then plug back into the second equation.
2x + 9(0) = 24
2x = 24
x = 12
Plug back into the first equation to check.
