The answer would be B. You multiply the 2 on both sides, getting 12 on the right. Then you divide by -1, and that switches the sign and makes 12 negative.
Answer:
Step-by-step explanation:
A delivery of 4 boxes will contain 2 more defective lightbulbs than a delivery of 2 boxes.
The vertex to this quadratic equation is 2
<u>Answer</u>
y = -2x + 10
<u>Explanation</u>
The general equation for a straight line is y = mx + c where m and c are gradient and y-intercept respectively.
y=x/2+3 = y (1/2)x + 3
gradient = 1/2
Gradient of the line perpendicular to y=x/2+3 is;
m × 1/2 = -1
m = -2
Now we find the equation of a line passing through (1,8) and have a gradient of -2.
-2 = (y - 8)/(x - 1)
-2(x - 1) = (y - 8)
2 -2x = y - 8
y = -2x + 10
