This is combinations
exg. lets say you have 2 hats and 1 pair of shoes, the answe ris 2 options, if 2 hats and 2 pairs of shoes, the answer is 4 because 2 times 2=4
3 options for sandwitch
3 soup
4 salad
2 drink
we multiply all together
3 times 3 times 4 times 2=72 options
Answer:
D
Step-by-step explanation:
Here, we want to get the equation of the line perpendicular to;
y = -3x + 2
From here, we can compare with the standard form of the equation of a straight line which is;
y = mx + c
From here m = -3
The slope is -3
Now, if two lines are perpendicular, the product of their slopes is -1
Thus;
-3 * m = -1
m = 1/3
So we want to select an equation out of the options that has a slope of 1/3
Let us take a look at the last option
x -3y = 3
3y = x-3
divide through by 3
y = x/3-1
So here the coefficient of x is 1/3 which is the slope of the perpendicular line that we are looking for and is our slope
