Answer:
-10
Step-by-step explanation:
= -X - XY
= -2 - 2×4
= -2 - 8
= -10
therefore, -X - XY = -10
Answer:
y = 8x + 2
Step-by-step explanation:
Slope-intercept form: y = mx + b
m = slope
b = y-intercept 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:
Step-by-step explanation:
-2x+y=4
-2(1)+2=4
-2+2=0, not 4.
Therefore, (1, 2) is not a solution to this equation.
