Answer

(4x-5) = -20 (2x+8) = 2

Step-by-step explanation:

2 x − 8 = 2 2x-8=2 2x−8=2. Add 8 to both sides. Simplify 2 + 8 2+8 2+8 to 10. Divide both sides by 2. If its wrong then I’m very sorry but I’m sure this is correct.

What is the value of the rational expression 2x^2+5x+9/x^2+2x-1 when x=-2
Sergio039 [100]

Answer:

The value of the Rational expression when x=-2 is: -7

Step-by-step explanation:

For this exercise is important to remember:

  • When a negative number is raised to an even power, the result will be positive.
  • The multiplication of signs:

       (+)(+)=+\\(-)(-)=+\\(-)(+)=-

Then, given the following Rational expression:

\frac{2x^2+5x+9}{x^2+2x-1}

You need to follow these steps in order to find its value when x=-2:

1. Substitute the given value of "x" (x=2) into the expression:

 \frac{2(-2)^2+5(-2)+9}{(-2)^2+2(-2)-1}

2. Evaluate and simplify:

\frac{2(4)+5(-2)+9}{4+2(-2)-1}=\frac{8-10+9}{4-4-1}=\frac{7}{-1}=-7

How much is the interest on my loan?
kirill [66]

Answer:  The interest is:  " $ 64 .00 " .

_____________

Step-by-step explanation:

_____________

Take note of the formula:

" Ⅰ = Prt " ;

→ that is:

_____________

→   " Ⅰ = P * r * t " ;

_____________

In which:  

_____________

 " Ⅰ = the interest " ;

 " P = the Principal amount of money " ;

 " r = rate " (expressed as the "decimal form" of the percentage) ;

 " t = time " (in years) ;

_____________

We are given:  

_____________

 P = $400 ;

 r = 0.08 ;  

{<u>Note of interest</u>:  That is " 8% " ; since "8 % "  = "(8/100)" ;

                                                                          = "(8 ÷ 100)"

                                                                          = " 0.08 ".}.

 t = 2 ; {that would represent:  " 2 (two) years".}.

_____________

We are to solve for "Ⅰ" ; the amount of "Ⅰnterest" :

→ To solve for "Ⅰ " ; we plug in our given values; and calculate:

_____________

  →  Ⅰ = P * r * t ;

        = 400 * 0.08 * 2 ;

        = 64 .

_____________

  →  Ⅰ = $ 64.00 .

_____________

Hope this is helpful to you!

Best wishes!

If you scale down the ratio on the left, what will you get for the unknown quantity on the right? 434 miles14 gallons = ?2 gallo
jarptica [38.1K]

Answer:

option (A) 62 miles

Step-by-step explanation:

Data provided in the question:

Ratio on the left = 434 miles : 14 gallons

ratio on the right = ?? : 2 gallons

Now,

The ratio on the both sides are equal

let the unknown value in the ratio be 'x'

Now, the ratio a : b can also be represented as \frac{a}{b}

therefore,

434 miles : 14 gallons = x : 2 gallons

or

⇒ \frac{\textup{434 miles}}{\textup{14 gallons}}  = \frac{\textup{x}}{\textup{2}}

or

⇒ x =  \frac{\textup{434 miles}}{\textup{14 gallons}}\times2 gallons}

or

⇒ x = 62 miles

Hence,

the correct answer is option (A) 62 miles
