Answer: 42
Step-by-step explanation:
x/3-4=10
x/3=10+4
x/3=14
(x/3)*3=14*3
x = 42
Answer:-12=-24 FALSE
Step-by-step explanation:
6-18= -12
18-42= -24
The statement is false

When the first equation is written in slope-intercept form it becomes
y = 3x + 3
This shows it to describe a line with the same slope but different intercept as the line described by the second equation.
The lines are parallel.
Answer:
3(4x - 1)(2x + 3)
Step-by-step explanation:
Rearrange the equation into standard form
Subtract 9 - 30x from both sides
24x² + 30x - 9 = 0 ← in standard form
Take out 3 as a common factor
3(8x² + 10x - 3) = 0 ← 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 = 8 × - 3 = - 24, sum = 10
The factors are - 2 and + 12
Use these factors to replace the x- term, that is
8x² - 2x + 12x - 3 ( factor the first/second and third/fourth terms )
2x(4x - 1) + 3(4x - 1) ← take out the common factor (4x - 1)
(4x - 1)(2x + 3)
24x² + 30x - 9 = 3(4x - 1)(2x + 3) ← in factored form
