The number of a certain company's video stores can be approximated by the linear equation y= -264x+4682, where x is the number of years after 1990.

find the missing coordinate for the ordered pair solution (

-what's the y-interpret and x-interpret?

Missing co-ordinate for the ordered pair is

Y-intercept is

X-intercept is

Step-by-step explanation:

The number of a certain company's video stores can be approximated by the linear equation

where is the number of stores and represents the number of years after 1990.

To find the missing co-ordinate for the ordered pair solution

For the ordered pair, we are given the value which is =7 i.e 7 years after 1990. Thus we will plugin in the linear equation to get the value which is number of stores after 7 years from 1990.

Thus the ordered pair is

To find y-intercept which is the point where the line touches the y-axis, we would plugin in the equation as the x-coordinate is 0 at y-axis.

Thus y-intercept is at point

To find x-intercept which is the point where the line touches the x-axis, we would plugin in the equation as the y-coordinate is 0 at x-axis and thus for

Subtracting both sides by 4682.

Dividing both sides by -264

∴

Thus x-intercept is at point

b. 2 and 4

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
