Answer:

y = 0.125x + -1.375

Step-by-step explanation:

You can try and use desmos.com to help you graph these 2 points. My algebra teacher recommended it if you don't have a physical graphing calculator!

Help! Algebra! please answer if you only know! and make it undertanding!
snow_lady [41]
1. a. Pretty much, you just have to rearrange it so that the highest power is in the front. So, here's your answer:
-6x^4+4x^2+2
b. It's a 4th-degree polynomial. A degree means that "what's the highest power?"
c. It's a trinomial. It has 3 terms, hence it's a trinomial.

2. a. Since it's an odd power and a negative coefficient, it will be:
x→∞, f(x)→-∞
x→-∞, f(x)→∞
b. The degree is even and the coefficient is negative, so it will be:
x→∞, f(x)→-∞
x→-∞, f(x)→-∞

3. a. This basically means that if you solve for x, you should get -2, 1, and 2. So, to do this, you can just write it in factored form and multiply inwards using any method of your choice (remember that in the parentheses, you should get the above value if you solve for x):
f(x) = (x-2)(x+2)(x-1)
If you multiply it out, you get (also your answer):
x^3-x^2-4x+4

4. The zeros are at x = 3, 2 and -7. Multiplicity of 3 is 1, for 2 it's 2, and for -7 it's 3.

Hope this helps!

Find the domain and range of 1/t+2
kotegsom [21]

Answer:

Domain = (-∞, -2) ∪ (-2, ∞).

Range =  (-∞, 0) ∪ (0, ∞).

Step-by-step explanation:

t can't have the value -2 because that would make  1/(t + 2) = 1/0 which is undefined.

So the domain is All real values of t. except t = -2.

As t approaches infinity or negative infinity  f(t) approaches  zero, and as t approaches -2 from below or above f(t) approaches negative infinity or positive infinity.

Karina is designing a logo on a coordinate plane. The logo is a square whose area is 200 square units. She places a circle in th
Katarina [22]

Answer:

D

Step-by-step explanation:

To find the percentage we must first find the area of the circle:

We can find the radius of the circle using the distance formula;

⇒ d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}

⇒ r = \sqrt{(6.3 - 0)^{2} + (1.6 - 0)^{2}}

⇒ r = 6.5

Now we calculate the area;

⇒ A = \pi r^{2}

⇒ A = \pi (6.5)^{2}

⇒ A = \frac{169}{4}\pi

To get the percentage we divide the area of the circle by the square’s are and multiply by 100;

⇒ Percentage = \frac{42.25\pi }{200} * 100

⇒ Percentage = 66 (2sf)

Answer:

<h3>y = 35x</h3>

Step-by-step explanation:

If you notice, point 4 on the x-axis (horizontal) coincides with 140 on the y-axis.
