12x^2-4x-5=0

12x^2+6x-10x-5=0

6x(2x+1)-5(2x+1)=0

(6x-5)(2x+1)

6x-5=0 , 2x+1=0

6x=5 ,  2x=-1

x=5/6 , x=-1/2

The population of mastertown was 23,000 in 2012. assume that mastertowns population increases at a rate of 2% per year. write an
Svetlanka [38]
Alright, let's interpret it, first.

The question is asking us to first find two percent of 23,000, then right an equation.

Alright, first, let's find two percent of 23,000. To find that we must do 0.02*23,000

I got 460

So we know that Mastertown's population is increasing by 460 people per year. All we have to do now is plug that into the equation.

Population (y)= 460* amount of years (x)

So our final equation is y = 460x

Hope this helped! Ask any questions about it!

onji has $5.25 in nickels and dimes.The coin value can be modeled by the equation 0.10d + 0.05n = 5.25, where d represents the n
Maru [420]
This is how you solve this problem:
.10d + .05n = 5.25

(plug in the number of dimes we have)

(21 x .1) + .05n = 5.25

(multiply number of dimes x value of the dime)

2.10 + .05n = 5.25

(subtract 2.10 from both sides)

.05n = 3.15

(divide both sides by .05 to get the number of nickels)

n = 63 nickels

Hope this helps!

Answer:

x-int (2, 0)

y-int (0, 3)

General Formulas and Concepts:

  • The y-intercept is the y value when x = 0.  Another way to reword that is when the graph crosses the y-axis.
  • The x-intercept is the x value when y = 0.  Another way to reword that is when the graph crosses the x-axis.

Step-by-step explanation:

<u>Step 1: Locate x-intercept</u>

x-int (2, 0)

<u>Step 2: Locate y-intercept</u>

y-int (0, 3)

Lines k and p are perpendicular, neither is vertical and p passes through the origin. Which is greater? A. The product of the sl
AlladinOne [14]
What do we know about those two lines?

They are perpendicular, meaning they have the same slope.
We know the slope of both is not zero (neither is vertical).
Therefore either
1) Both slopes are positive and therefore the product is positive
2) Both slopes are negative and therefore the product is positive (minus by a minus is a plus)

For the y intercepts, we know that the line P passes through the origin.
Therefore its Y intercept is zero.
[draw it if this is not obvious and ask where does it cross the y axis]
Therefore the Y intercept of line K and line P is zero.
[anything multiplied by a zero is a zero]

So we know that the product of slopes is positive, and we know that the product of Y intercepts is zero.
So the product of slopes must be greater.
