Answer:
-7
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
7x-4 6x-4-x
Combine like terms on the second expression
7x -4 6x -x -4
5x -4
These are not equivalent expressions
7x -4 does not equal 5x-4
Answer:
-3x^2-21x+24
Step-by-step explanation:
Kindly separate the answer choices: (x - 4), (x + 1), (x + 4) , (x - 1). The trinomial is thus -3x^2-21x+24, which can be factored as follows: -3(x^2 + 7x - 8)
Then we have -3x^2-21x+24 = -3(x^2 + 7x - 8), which factors further into:
-3(x + 8)(x -1) and so we conclude that the only binomial that is a factor of
-3x^2-21x+24 is (x - 1).
Answer:
You can calucate b by using pythagorean theorem:
a² + b² = c²
21² + b² = 29²
b² = 841 - 441 = 400
b = √400 = 20 (m)

Step-by-step explanation:
Your first step is to solve for y on both equations.
You solve treat the inequality sign just like an equal sign and solve for it.
Graph your equations as if the inequality sign isn't there.
Use dotted lines for < and >
Use solid lines for ≤ and ≥
If it's less than, < or ≤, then shade underneath the line.
If it's greater than, > or ≥, then shade above the line.
