Answer:
I cant do them all for you, but essentially every equation there is an a, plug in 10 for a. Every equation with b, plug in 9 and every equation with c plug in 4. Then Solve/simplify

Answer:
x ≥ 88
Step-by-step explanation:
In order to have at least an average of 80 after 4 tests, the sum of her scores must be at least 80 * 4 = 320 so we can write the following inequality:
71 + 78 + 83 + x ≥ 320
232 + x ≥ 320
x ≥ 88
Slope like you wrote is rise over run. That means from the point given: (1,1) you will rise up by the first number and run to the left (negative)/right (positive) depending on the sign of the number.
EX: 5/2, rise up 5 and run to the right by 2. Your line’s direction should be pointed upwards.
EX: 2, your two numbers is 2 and the invisible 1 (apply the same method as the first example).
