You could see the pattern

it cost 3.8 cent to print 1 dollar,

It cost 2 x 3.8 cents to print 2 dollar

it cost 3 x 3.8 cents to print 3 dollar

First equation 
f(x) = 3.8 x

Same with second equation,
f(x) = 15x

for equation 3, it would be :

y = 1.50 x - 0.8x

Hope this helps

Which of the following would be the . most logical first step to solving this quadratic equation
mrs_skeptik [129]
Hello!

When solving a quadratic equation, we should begin by confirming that the right side is equal to 0. The equation above, however, contains a 2 on the right side.

Therefore, the most logical first step would be to subtract 2 from both sides, leaving the ride side equal to 0.

I hope this helps!

Factor 5v^2 - 23v - 10​
AfilCa [17]

Answer:

(5v + 2)(v - 5)

Step-by-step explanation:

Hello!

The expression is written in the form of ax^2 + bx + c

Let's factor by grouping:

ac  = -50

The sum of the factors of -50 should add up to -23.

-25 and 2 work for this.

Expand and factor:

  • 5v^2 - 23v - 10
  • 5v^2 - 25v + 2v - 10
  • 5v(v - 5) +2(v -5 )
  • (5v + 2)(v - 5)

The factored expression is (5v + 2)(v - 5)
