Answer:
C) (x,y) → (x,y+6)
Step-by-step explanation:
As the x value stays the same after the transformation, we know that there can be no changes to the value x, automatically limiting the options to answer C.
The mathematical way to find the value y is changed by would be by setting up a small equation as follows:
, where n is some number that the y value is altered by.
Solving for n gives the value 6, proving that the translation must add 6 to the y value.
Answer:
See below.
Step-by-step explanation:
So, Nikki earns $12 per hour.
And she also earns a 5% or 0.05 commission of her total sales each day.
On Saturday, she worked eight hours and she earned $139. In other words, she earned 8(12) or $96 from working her hours and another $43 (139-96) from her commission.
Thus:
Where x represents Nikki's total sales on Saturday.
Further notes:
To solve, subtract 96 from both sides and divide by 0.05:
Thus, her total sales that day were $860.
Answer:
The equation of line that passes through the point (8,-7) and is parallel to the line 5x+4y=16 is
Step-by-step explanation:
We need to write an equation of the line that passes through the point (8,-7) and is parallel to the line 5x+4y=16.
The equation will be of form where m is slope and b is y-intercept.
Finding slope of the line:
Since both the lines are parallel, and we know that parallel lines have same slope.
The slope of given line can be found by writing in slope-intercept form
Comparing with the slope m is:
So, the slope of required line is:
Now, finding y-intercept b
y-intercept can be found using slope and point (8,-7)
So, we get y-intercept: b=3
Now, the equation of required line having slope and y-intercept b=3 is:
So, the equation of line that passes through the point (8,-7) and is parallel to the line 5x+4y=16
