You can choose values of x and calculate , values of y
for example,
2y= x+1
y=(1/2)x +1/2
x=0, y=(1/2)*0 +1/2 = 1/2 point (0, 1/2)
x=3, y=(1/2)*3+1/2=3/2+1/2=4/2=2 point (3, 2)
and so on
The answer is
To find how many ounces you need to make, you multiply the number of packs by how many ounces.
So, it would look like:
36*2.35=84.6
15*10.8=162
Then you add the ounces together and you have your answer:
162+84.6=246.6 ounces
Given a scalar number
![a](https://tex.z-dn.net/?f=a)
and a vector
v, the product between
![a](https://tex.z-dn.net/?f=a)
and
v is a vector, with
- magnitude given by the product between the absolute value of
![a](https://tex.z-dn.net/?f=a)
and the magnitude of
v- direction given by the sign of
![a](https://tex.z-dn.net/?f=a)
: if a is positive, the final vector has same direction of
v; if a is negative, the final vector has opposite direction to
v.
In our problem, the scalar number is
![- \frac{\pi}{4} =- \frac{3.14}{4}=-0.79](https://tex.z-dn.net/?f=-%20%5Cfrac%7B%5Cpi%7D%7B4%7D%20%3D-%20%5Cfrac%7B3.14%7D%7B4%7D%3D-0.79%20)
. This means that the product between the vector and this number:
- has magnitude equal to
![|-0.79| = 0.79](https://tex.z-dn.net/?f=%20%7C-0.79%7C%20%3D%200.79)
times the magnitude of the vector
- has opposite direction with respect to the original vector (because the scalar
![a](https://tex.z-dn.net/?f=a)
is negative)
Therefore, the correct answer is
<span>B.) The vector will change direction and decrease in magnitude.</span>
