What value of ​x satisfies the equation 6.4−2x−6.63x=610.5 ?

Mathematics
1 answer:
Nesterboy [21]2 years ago
4 0
6.4 - 2x - 6.63x = 610.5
subtract 6.4 from both sides 
-2x -6.63x =604.1
collect like terms 
-8.63x = 604.1
divide both sides by -8.63

x= -70

Which function has a vertex at (2, –9)?
Ivahew [28]
The solutions or roots so-called are really just the x-intercepts, and for a quadratic equation, the vertex is found right half-way between those x-intercepts.

we can get the intercepts by zeroing out "y" or f(x), so let's take a peek at one of those,

\bf \stackrel{f(x)}{0}=(x-5)(x+1)
\\\\\\
0=x-5\implies \boxed{5=x}\qquad \qquad \qquad \qquad 0=x+1\implies \boxed{-1=x}

so, the x-intercepts or solutions are at 5 and -1, let's take a peek what's the halfway point.

-1----0----1----  2  ----3-----4------5

well then, now we know the vertex is at x = 2, but, what's the y-coordinate of it anyway?

y = (x - 5)(x + 1)

y = (2 - 5)(2 + 1)

y = (-3)(3)

y = -9

ella [17]

Answer:

Lift

Step-by-step explanation:

Finding patterned and relationship between large sets of data can be obtained using the association rule as it finds insights, relationships and trends within sets of data variables. Lift is a parmater of interest whichbus used when performing analysis on association between variables in datasets. The Lift is literally the ratio of confidence to expected confidence. Where, the confidence of association is divided by the expected confidence (benchmark confidence).

A rectangular gym has an area of 4x^2 ft². The school decides to add a new weight room. The total area of the gym and the weight
anygoal [31]
For this case the new area is the sum of two areas:
 Area = rectangular gym + weight room
 Area = (4x² + 520) ft²
 In addition, we know that
 rectangular gym = 4x ^ 2 ft²
 Therefore, the term 520 represents a new weight room
 answer
 The constant term represent a new weight room
