Find the equation of a line parallel to x=7 and passing through the point (2, -5)
Anarel [89]

Answer:

x = 2

Step-by-step explanation:

x = 7 is a vertical line parallel to the y- axis.

Thus a parallel line will also be vertical with equation

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (2, - 5) with x- coordinate 2, thus

x = 2 ← equation of parallel line

Isabella painted her bedroom. She used 2 gallons of paint and finished in 8 hours. At what rate did Isabella paint the room?
GrogVix [38]

Answer:  " \frac{1}{4} gal /hr ;  or, write as:  " 0.25 gal/hr. " .

_______________

Step-by-step explanation:

_______________

This is a "unit rate" problem;

that is:  we want to solve for a particular quantity per [single] unit.

_______________

→ in this case, per single "hour" ;

_______________

So we convert:

_______________

" 2 gal per 8 hours" ; to the correct number of:

 _?_ gal per [single] hr.

_______________

{<u>Note</u>:  "gal" refers to:  "gallon(s)" ;

           "hr" refers to:  "hour(s)" .}.

_______________

→ " \frac{2 gal}{ 8 hr} = [\frac{2}{8}] gal / hr. " ;

_______________

→ " { \frac{2}{8} = [2÷2] / [8÷2] = 1/4 ;

_______________

So, the answer is:  

  → " \frac{1}{4} gal /hr " ;

_______________

 or: write as decimal:

  → " \frac{1}{4} = (1 ÷ 4) = 0.25 " ;

_______________

write the answer as:

_______________

  → " 0.25 gal/hr. "

_______________

Or, when we had:

 → "2/8" gal/hr ;

_______________

 Use calculator:

 → " \frac{2}{8} = "2 ÷ 8" ;

 =  " 0.25 gal/ hr.

_______________

So:  The correct answer is:

_______________

 " \frac{1}{4} gal /hr ;  or, write as:  " 0.25 gal/hr. " ;

_______________

Hope this is helpful to you!

Best wishes in your academic endeavors—

  and within the "Brainly" community!
