Answer:
Y=3/1x+25
Step-by-step explanation: I believe this is correct. I was doing this a while ago so I might have it wrong. Y Is the money on the card, m, or 3/1 is the slope. B is the Y-intercept, which is 25.
Answer:
4845 ways
Step-by-step explanation:
To solve this problem we use the formula of combinations

Where n is the total number of students that can be chosen and you choose r from them.
So

Note that in this case the order in which the 4 students are chosen does not matter.
Then


The magnitude of each vector is the Pythagorean sum of its components.
a. |v1| = √(2² + (-6)²) = √40 = 2√10
|v2| = √((-4)² + 7²) = √65
b. To make each vector into a unit vector, divide each component by the vector's magnitude.
u1 = v1/|v1| = (2/(2√10), -6/(2√10))
u1 = (√10/10, -3√10/10)
u2 = v2/|v2| = (-4/√65, 7/√65)
u2 = (-4√65/65, 7√65/65)
Hello,
-2m^3+m²-m+1=(m+1)(-2m²+3m-4) +5
We must add -5 ; the remainder will be 5-5=0.
