Mathematics
1 answer:
jek_recluse [69]3 years ago

Answer:

Part A. C     Part B.  D

Step-by-step explanation:

Part A: First, if you know you want to have equal than or more than 78 then you know it goes on the right side of the inequality. Next, you have to pay attention to the inequality and remember it's meaning. !!!Remember!!!!

This: 10<11 means 10 is less than 11, or you can read it as 11 is greater than 10. Use that to choose between C and D.

Part B: This question requires you to solve the inequality and then construct a graph. You can easily take off A and C because you know you already have positive 13 sold and therefore your total will be positive.

So, solve the inequality to find C and reread the question so you remember the goal of this coat drive (remember the sign you used in Part A); once you do that you can choose between B and D.

What is the line of SYMMETRY for they PARABLLA who’s equation is y=3x2+24x-1?
Arada [10]

Answer

The line of symmetry x = -4

Step by step explanation

Here we have to use the formula.

The symmetry of a parabola x = -b/2a

Now compare the given equation y = 3x^2 + 24x -1 with the general form y = ax^2 + bx + c and identify the value of "a" and "b"


Here a = 3 and b = 24. Now plug in these values in to the formula to find the line of symmetry.

x = -24/ 2(3)

x = -24/6

x = -4

Therefore, the line of symmetry x = -4.

Thank you.

Anyone know this answer?
damaskus [11]
La of sine:

sinC/c = sinB/b==> sin  37°/8 = sin B/12 ==> sin B = 0.903


arcsinB or sin⁻¹ B = 64.5°, & sin (B°) = sin (180° - B°), then

sin(64.5) = sin(180°-64.5°) ==> B = 64.5° or 115.5°

Answer:

The correct choice is the third answer.

Step-by-step explanation:

The arrow on top of the letters means that they would be parallel.  If you look closely at the diagram, you can see that both QR and TU go in the same direction and will never intersect.

lakkis [162]
We can factor out the 4 to get
4(2a^3b^8+ab-4ab^8)
we can also factor out the ab
4ab(2a^2b^7+1-4b^7)
that is factored completely

Which of the following systems of inequalities has point C as a solution?
Ede4ka [16]

Answer: A

Step-by-step explanation:

C lies below g(x) and f(x), so we need f(x) \leq 3x+4 and g(x) \leq -\frac{1}{2}x-5.
