6.4/3.5, OR about 1.83
First job is to isolate the y.
3.5y=6.4x+7
Now divide both sides by 3.5 to get the equation into y=mx+b form.
That leaves a rounded equation of y=1.83x+2
In y=mx+b, the m is the slope. This means the slope of this line is 1.83, or 6.4/3.5
2(-2) + 7
= -4+7
= 3
so when x = -2 y = 3
Yes
<span>given ordered pair is a solution to the equation </span>
The number 23.57 is 10 times larger than 2.357.
You must do in this case is composition of both functions:
a (x) = 3x + 1
b (x) = root (x-4)
Making the composition
b (a (x)) = root ((3x + 1) -4)
Rewriting:
b (a (x)) = root (3x-3)
b (a (x)) = root (3 (x-1))
Answer:
The domain of the function is:
x> = 1
Equivalently:
[1, inf)
A fraction is defined as as part of one,
think of it like this
you have 1 pie
your brother cuts it into 4 pieces
you take 1
you took 1 out of 4 or 1/4 pie
so fractions
you have a numberator (top) and denomenator (bottom)
the numberator tells how many pieces you have
the denomenator tells how many pieces are needed to make 1 whole pie
so a fraction is normally where the deomenator is bigger than the numerator
so some fractions
1/2
1/3
1/4
1/5
1/6
2/5
