Answer:

D - the slope will be at 25

Step-by-step explanation:

Taking the first two values

slope = (y2 - y1) / (x2 - x1) = (125 - 100) / (3 - 2) = 25 / 1 = 25

D
Number of hours is x values and cost of service is y.
To find slope you have to find the change in y over the change in x.
We can use any points in the table to calculate this amount.
Eg, 3-5 hours and 125-175 dollars.
The difference in y values is $50 and the difference in hours is 2.
50/2=25
The slope is 25

Simplify.

First I'd expand the brackets so that you can re-simplify the values, so:
(2x + 3)(3x + 4)
6x^2 + 9x + 8x + 12
6x^2 + 17x + 12
The answer A. 2x(3x + 4) + 3(3x + 4) can be simplified the same way, with 6x^2 + 8x + 9x + 12, and so the answer is A. I hope this helps!

Graph the following quadratic function using transformations

lorasvet [3.4K]

You start with the basic y=x^2.
That’s the parabola with a vertex at (0,0), opening up, etc.

The transformation aspect is the “+7” portion. This “+7” shifts the entire graph of y=x^2 up by 7 units.
The vertex is now (0,7), it still opens up, etc.

It’s kind of a silly question for your teacher to ask when the graph given only goes up to 6.

Use a double angle or half angle identity to find the exact value of each expression

STatiana [176]

Answer:

Step-by-step explanation:

There are 2 very distinct and important things that we need to know before completing the problem. First is that we are given that the cos of an angle is 1/3 (adjacent/hypotenuse) and it is in the first quadrant. We also need to know that the identity for sin2θ = 2sinθcosθ.

We already know cos θ = 1/3, so we need now find the sin θ. The sin ratio is the side opposite the angle over the hypotenuse, and the side we are missing is the side opposite the angle (we do not need to know the angle; it's irrelevant). Set up a right triangle in the first quadrant and label the base with a 1 (because the base is the side adjacent to the angle), and the hypotenuse with a 3. Find the third side using Pythagorean's Theorem:

$3^2=1^2+y^2$ which simplifies to
