Answer:
m= -5/2
Step-by-step explanation:
formula for slope(m) : ΔY/ΔX (change in y coordinates - change in x coordinates)
change in y coordinates: 5-(-5) = 10
change in x coordinates: -4-(0) = -4
10/-4 = -5/2= -2.5
Answer:
<u>The expression is 6v² + 6v - 120</u>
Step-by-step explanation:
v = Car's speed
Let's write the expression for 6 times the square of a car's speed plus 6 times the car's speed minus 120, this way:
6v² = 6 times the square of a car's speed
6v - 120 = 6 times the car's speed minus 120
Now, let's add the operator (+):
6v² (6 times the square of a car's speed) + 6v - 120 (6 times the car's speed minus 120)
<u>The expression is 6v² + 6v - 120</u>
Answer:
24 ways.
Step-by-step explanation:
In this case, you just need a factorial.
For the first seat, you have 4 students you can place.
For the second seat, you have 3 students.
For the third, you have 2.
For the fourth, you have 1.
So, you can arrange the students by doing 4 * 3 * 2 * 1 = 12 * 2 = 24 ways.
Hope this helps!
