Dependent variables are something that depends on other factors. therefore, if the quality of the public school teacher is poor, it will affect the student's learning badly, and if the teacher's teaching is strong, it affects the student's learning greatly. The student's learning depends on how well the teacher teaches.
Answer is B: 150
write two equations
r+s=190
4r+3s=720
solve by substitution
the get r=150 s=40
Answer:
8
Step-by-step explanation:
8y-3y=40
5y. = 40
y. =8
the value of y is 8.
...
1. 2x^2-x-15=0
A = 2
B = -1
C = -15
2. 10^2-2x=0
A = 10
B = -2
C = 0
3. x^2–3x-40=0
A = 1
B = -3
C = -40
4. x^2+3x-2=0
A = 1
B = 3
C = -2
5. 4x^2-17x+8=0
A = 4
B = -17
C = 8
Remember the equations should look like Ax^2+Bx+C=0 (in this order!!)
