Answer:
And we want to find the domain. And that represent the possible values for x. Since we have a quadratic function we have that the domain would be all the reals, and we can write:
![D= [x \in R]](https://tex.z-dn.net/?f=%20D%3D%20%5Bx%20%5Cin%20R%5D)
Where D represent the domain and R the set of the real numbers.
Step-by-step explanation:
For this case we have the following function:
And we want to find the domain. And that represent the possible values for x. Since we have a quadratic function we have that the domain would be all the reals, and we can write:
Where D represent the domain and R the set of the real numbers.
A discount of 20% multiplies the number by 1-.20=.8, so the price is going to be .8p.
Answer:
18-4y=62, u can solve it if u want and u can also subsitute any variable or a constant
Answer:
8x + 1/2 or 8x + 0.5
Step-by-step explanation:
-6x + 3 3/4 + 14x - 3.25
u can either convert the fraction to a decimal or convert the decimal into a fraction, i'm going to do the latter
-6x + 3 3/4 + 14x - 3 1/4
rearrange to make it easier, don't need to do this i'm just doing this for the sake of it
-6x + 14x + 3 3/4 - 3 1/4
8x + 2/4, simplify this
8x + 1/2
The decimal way if u want:
-6x + 3 3/4 + 14x - 3.25
-6x + 3.75 + 14x - 3.25
-6x + 14x + 3.75 - 3.25
8x + 0.5
