Question

Please confirm!!!! Will Medal (and must be correct)

F(x) = 7 - 2x

= All real numbers greater than 7 (???)

Answer 1

Since x is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation.
7−2x=F(x)

Since 7 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 7 from both sides.

−2x=−7+F(x)
Reorder the polynomial −7+F(x) alphabetically from left to right, starting with the highest order term.

−2x=F(x)−7

Answer 2

D:

Answer 3

Divide each term in the equation by −2.
\[-\frac{ 2x }{ -2 }=\frac{ F(x) }{ -2 }-\frac{ 7 }{ -2 }\]

Answer 4

Move the minus sign from the denominator to the front of the expression.
\[\frac{ 2x }{ 2 }=\frac{ F(x) }{ -2 }-\frac{ 7 }{ -2 }\]

Answer 5

So less than 5?

Answer 6

Cancel the common factor of 2 the expression \[\frac{ 2x }{ 2 }\]
\[x=\frac{ F(x) }{ -2 }-\frac{ 7 }{ -2 }\]

Answer 7

All real numbers less than 5?

Answer 8

No

Answer 9

Less than seven then...?

Answer 10

A. All real numbers less than 5
B. All real numbers less than 7
C. All real numbers greater than 7
D. All real numbers greater than 5

Answer 11

Move the minus sign from the denominator to the front of the expression.
\[x=-\frac{ F(x) }{ 2 }-\frac{ 7 }{ -2 }\]
Move the minus sign from the denominator to the front of the expression.
\[x=-\frac{ F(x) }{ 2 }+\frac{ 7 }{ 2 }\]
Reorder the polynomial alphabetically from left to right, starting with the highest order term.
\[x=-\frac{ 7 }{ 2 }-\frac{ F(x) }{ 2 }\]

Answer 12

Are you looking for the range?
