Step-by-step explanation: The formula for 90 degrees counter-clockwise is (x, y) to (-y, x)
Answer:
14 candy Bars
Step-by-step explanation:
Let's under the question before we attempt it.
Total number of Candy Brooklyn is supposed to sell = 20
Percentage of Candy Bars sold= 70%
To know the exact number of Candy sold, it's means we must know the exact value of 70% of 20.
To solve this, we just proceed with mathematical operations.
Therefore:
70% of 20
= 70 / 100 * 20
= 1400 / 100
= 14.
It therefore means that, Brooklyn sold 14 Candy Bars
Math is fun! Lets Keep learning
For lines to be perpendicular their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1, and in this case:
-m/4=-1
-m=-4
m=4, so the slope of the perpendicular line is 4 so we have thus far:
y=4x+b, using point (-4,3) we can solve for the y-intercept, "b"
3=4(-4)+b
3=-16+b
19=b, so our line is:
y=4x+19
Answer:
0 = 4x
Step-by-step explanation:
-2(2 - 2x) = 4 - 8(1 - x)
-4 + 4x = 4 - 8 + 8x
-4 + 4x = -4 + 8x
-4 + 4 = 8x - 4x
0 = 4x
