(1.7 + 3.2 + 2.8 + x) / 4 = 2.5
(7.7 + x) / 4 = 2.5.....multiply both sides by 4, eliminating the /4
7.7 + x = 2.5 * 4
7.7 + x = 10
x = 10 - 7.7
x = 2.3 <====

sineoko [7]

Answer:

<em>It has infinitely as many solutions</em>

Step-by-step explanation:

Equations and Identities

When dealing with equations, we must find values of the variable who mak the expression become an identity.

The expression is an identity regardless on what the value of x is, so we can say the equation has infinite as many solutions. For example x=0 will make the expression look like 3=3 which is an identity. If x=8, we'll obtain 27=27 and so on

Which represents a linear function? a. Y=2x b. 2x^2 c. Y=1/x
Kobotan [32]

Answer:

Step-by-step explanation:

Y=2x is linear (also proportional) since it involves only the first power of x

2x^2 is not linear, due to the second power of x (x^2); it is quadratic

Y = 1/x is not linear, due to x being in the denominator.
