Mathematics
1 answer:
____ [38]3 years ago
5 0

Answer:

a =3

b = -5

c = 4

Step-by-step explanation:

3x^2+4=5x

Subtract 5x from each side

3x^2-5x+4=5x-5x

3x^2-5x+4=0

The equation is in the form

ax^2 +bx+c =0

a =3

b = -5

c = 4

7 − 9x − (x + 12) less than or equal to 25?
Nonamiya [84]

Answer:

x  ≥-3

Step-by-step explanation:

7 − 9x − (x + 12) less than or equal to 25

7 − 9x − (x + 12) ≤ 25

Distribute the minus sign

7 − 9x − x - 12 ≤ 25

Combine like terms

− 10x −5 ≤ 25

Add 5 to each side

− 10x −5+5 ≤ 25+5

− 10x ≤ 30

Divide by -10. Remember that this flips the inequality

− 10x/-10 ≥30/-10

x  ≥-3
