Answer:

y=-2

Step-by-step explanation:

3(y-3)=-15

Divide both sides by 3:

3(y-3)/3=-15/3

Simplify:

3(y-3)/3=-15/3

3(y-3)/3

Divide the numbers:3/3=1

=y-3

Simplify:

-15/3

Divide the numbers:15/3=5

=-5

y-3=-5

Add 3 to both sides:

y-3+3=-5+3

Simplify:

y=-2

Determine what type of number the solutions are and how many exist for the equation 3x^2+7x+5=0
Hitman42 [59]

Answer:

Two complex (imaginary) solutions.

Step-by-step explanation:

To determine the number/type of solutions for a quadratic, we can evaluate its discriminant.

The discriminant formula for a quadratic in standard form is:

\Delta=b^2-4ac

We have:

3x^2+7x+5

Hence, a=3; b=7; and c=5.

Substitute the values into our formula and evaluate. Therefore:

\Delta=(7)^2-4(3)(5) \\ =49-60\\=-11

Hence, the result is a negative value.

If:

  • The discriminant is negative, there are two, complex (imaginary) roots.
  • The discriminant is 0, there is exactly one real root.
  • The discriminant is positive, there are two, real roots.

Since our discriminant is negative, this means that for our equation, there exists two complex (imaginary) solutions.

Solve for a: -8b+2a=6c
Fantom [35]

Answer:

a=3c+4b

Step-by-step explanation:

-8b + 2a = 6c

(-8b + 2a) + 8b = 6c + 8b

-8b + 2a + 8b = 6c + 8b

-8b + 8b + 2a = 6c + 8b

2a = 6c + 8b

2a/2 = 6c + 8b/2

a = (2x3)c + 2^{3} x b)/2

a = 3c + 4b
