Answer:
x = 2
Step-by-step explanation:
The parallel lines divide the transversals into proportional segments, that is
= ( cross- multiply )
9(x + 4) = 54 ( divide both sides by 9 )
x + 4 = 6 ( subtract 4 from both sides )
x = 2
Answer:
Ok:
Step-by-step explanation:
So f°g . means f(g(x)). (The ° should be more center and bigger but I don't know to do that on a keyboard). f(g(x)) means that you replace the x in f(x) with the g(x) function. i.e:
if f(x) = 2x+2
and g(x) =
f(g(x)) = .
Similarly, in this case, we get f(x) = 2x-3 and g(x) = 3x-2.
Then, f(g(x)) or f°g(x) is 2(3x-2) - 3.
And we plug in -2 to solve:
2(3(-2)-2)-3.
and get -19.
Check if I am wrong because everyone makes mistakes but that is the way to solve this.
The median and mode are the same. The low and high values are the same.
Answer:
24 yards, $77.40
Step-by-step explanation:
1) brown braid : 4*2.40 = $16.80
black lace : 7*2.40 = $29.40
gold ribbon : 13*2.40 = $31.20
2) 4 + 7 + 13 = 24 yards <
3) 16.80 + 29.40 + 31.20 = $77.40 <
