Which expression is equivalent to 8(5x - 3)?
A)
13x - 11
B)
13x - 24
40x - 11
D)
40x - 24

D) 40x - 24

Step-by-step explanation:

Once you open the bracket you have to times the inside numbers by the number out side of the bracket.

8 x 5x = 40x

8 x 3 = 24

Therefore, 8(5x - 3) = 40x - 24

828. all there is to it!

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
