c. As the hours of training increase by 5, the greeting cards made increases by 25.
d. As the hours of training increase by 5, the greeting cards made decreases by 25.
Answer:
y=0
Step-by-step explanation:
If x equals 28 then substitute it in the equation, 28+3y=28
Next, subtract 28 from both sides, 3y=0
Now that you have that its simple, y must equal 0
Answer:
2(4x + 1)(x + 1)
Step-by-step explanation:
Given
8x² + 10x + 2 ← factor out 2 from each term
= 2(4x² + 5x + 1)
To factor the quadratic
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 4 × 1 = 4 and sum = + 5
The factors are + 1 and + 4
Use these factors to split the x - term
4x² + x + 4x + 1 ( factor the first/second and third/fourth terms )
= x(4x + 1) + 1 (4x + 1) ← factor out (4x + 1)
= (4x + 1)(x + 1), thus
4x² + 5x + 1 = (4x + 1)(x + 1) and
8x² + 10x + 2 = 2(4x + 1)(x + 1) ← in factored form
