Hi,
Let's start with the equation:
(7)(11)+(3)(3)−16/2
Next multiply:
=77+(3)(3)−16/2
=77+9-16/2
Add:
=86−16/2
=86−8
=78
Have a great day!
6 x -5q = -30q
6 x 1 = 6
Therefore -30q + 6
There are 3 choices for the pants. Having selected a pair of pants there are 2 choices for a shirt. Therefore there are 3 * 2 possible choices for a pair of pants and a shirt. Each of these 6 possible choices can be combined with each of the 3 possible choices of a pair of shoes. So, the total number of choices of outfit is given by:
Y = 3x - 4.....the slope here is 3. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, u flip the slope and change the sign. So we will need a slope of -1/3...see how I flipped the slope of 3/1 and made it 1/3...and then changed the sign, making it -1/3.
y = mx + b
slope(m) = -1/3
(2,1)...x = 2 and y = 1
now we sub and find b, the y int
1 = -1/3(2) + b
1 = -2/3 + b
1 + 2/3 = b
3/3 + 2/3 = b
5/3 = b
so ur perpendicular equation is : y = -1/3x + 5/3
