4 0

Answer:

the domain is the set of x -values, the range is the set of y-values. I would have to say the domain is : R [ negative intinity, to infinity]. Equally, I would have to say the range is R [ Negative infinity,  to infinity]

How do you find the slope of a point line function !
guajiro [1.7K]

To find the slope of a function written in point-slope form, we must first know what point slope form is. Point slope form is:


y - y₁ = m[x - x₁]


In this function, m is the slope, so the find the slope of a point-slope line function, we just have to look at the value right outside the parenthesis on the right side of the equation.

What is the missing coefficient?
Afina-wow [57]

For this case we have the following expression:

(15x ^ 2 + 11y ^ 2 + 8x) - (7x ^ 2 + 5y ^ 2 + 2x) =

We eliminate the parentheses taking into account that:

- * + = -\\15x ^ 2 + 11y ^ 2 + 8x-7x ^ 2-5y ^ 2-2x

We add similar terms:

15x ^ 2-7x ^ 2 + 11y ^ 2-5y ^ 2 + 8x-2x =

Different signs are subtracted and the sign of the major is placed:

8x ^ 2 + 6y ^ 2 + 6x

Finally, the expression is reduced to:

8x ^ 2 + 6y ^ 2 + 6x

Answer:

8x ^ 2 + 6y ^ 2 + 6x

Option B

The length, width, and height of a right rectangular prism are multiplied by 23. What will be the effect on the volume of the pr
Yanka [14]

Since none of the options make sense with 23, I assume it was a typo, and you meant 2/3.

Let l,w and h be the length, width and height of the original prism, and l',w' and h' be the length, width and height of the new prism. We are given

l' = l\times \cfrac{2}{3},\quad w' = w\times \cfrac{2}{3},\quad h' = h\times \cfrac{2}{3}

Also, if we call V the original volume, and V' the volume of the new prism, we have

V = lhw,\quad V'=l'h'w'

Substitute the expressions for l', h' and w' in the formula for V':

V'=l'h'w' = l\times \cfrac{2}{3}\times w\times \cfrac{2}{3}\times h\times \cfrac{2}{3} = l\times h \times w \times \cfrac{2}{3}\times\cfrac{2}{3}\times\cfrac{2}{3} = V \times \left(\cfrac{2}{3}\right)^3 = V\times\cfrac{8}{27}
