Which statement is correct about the function y = 3x2 + 19x – 14?
sertanlavr [38]
You just have to factor the given expression. You do this by factoring the first term and the last term.

3x^{2} can only be factored with 3x • x, so let's put that into our parentheses.

(3x ?)(x ?)

Now the last term. -14 can be factored more ways than one. Here are some examples:

-14 <span>• 1
</span>14 <span>• -1
7 </span><span>• -2
-7 </span><span>• 2

We know we can't use the first two since they're not options in this question. We also know the middle term is something quite large, so that number is what should be multiplied by three.

(3x - 2)(x + 7)

Let's test it out. By multiplying the insides, the outsides, and adding them together. 

-2 </span><span>• x = -2x
</span>
7 <span>• 3x = 21x
</span>
21x - 2x = 19x

Aha! That is correct! Now that we've gotten that figured out, we can eliminate B and D. But what about the others? Well, I usually just graph out the factors with a calculator and see the zeroes from there, but since I don't have that luxury in this case. I'll have to find out some other way. I would say to multiply the factors by each other and switch the signs (without the x).

7 = -7

-2 x 3 = -\frac{2}{3}

-\frac{2}{3} = \frac{2}{3}

That should be your answer. If you have any questions, let me know.

1. Petra works as a delivery person for a restaurant. The graph shows a linear model for her
Charra [1.4K]

Answer: The points are, the top left one, (21,3) and the one on the bottom is (6, 12)

Step-by-step explanation: For the slope, we label one of the points, with y or x. For example, (21, 3) we would label 21 either y1 or x1. Say we put y2, then 3 would be x2. Moving on, (6,12) this time we could label 6 as either y1 or x1. Same thing, but this time we are going to label 6 as y1 and 12 x1. Again, it’s DOES NOT matter what you label them as.

Now to solve it, remember y numbers always go on top! M which is slope. M = y2 - y 1 / x2 - x 1 or with the numbers M = 21 - 6 / 12 - 3 = 15/9 simplified = 5/3

Write an equation to find the nth term. Then find ₐ₂₄<br> -1, -4, -7, -10,...
Maru [420]

The equation to find the nth term is:

an = a+(n-1)d

Where a is the first term in the sequence, which is -1 and d is the difference, which in this sequence the next term is found by subtracting 3 from the previous term, so d = -3 and n is the term you want to find.

The equation becomes:

an = -1 +(n-1)(-3)

a24 = -1 + (24-1)(-3) = -1 + (23(-3)) = -1-69 = -70
