in Youngstown, the population reached 4420 people in 1993. in 1998 the population was 5600 residents. what was the population in
Julli [10]
5600 - 4420 = 1180....so there is a difference of 1180 in a period of (1998 - 1993) = 5 yrs.

1180/5 = 236 people per yr

so in 1998 the population was 5600.....in 2000 (2 yrs later) the population would be : 5600 + 236(2) = 5600 + 472 = 6072 <==

Graph the equation y = 4/5x - 1
astra-53 [7]

Answer: The answer is the picture shown below

Step-by-step explanation:

To do this you will need to make a coordinate plane about 20 up and 20 down. So there is a formula that is y=mx+b which is called the slope intercept form and as you can see the problem given to you was already given in this formula. The variable m in the equation is the slope and slope is also known as rise (which basically means go up if positive and down if negative) over run (which is right if positive and left if negative) and as you can see in the equation the number 4/5 is the variable m. Since slope is rise over run 4 would be the rise and 5 would be the run, so you would go up 4 and right 5 because they are both positive. Now there is another variable that is b which would be the -1. In slope intercept formula b is the y intercept so -1 is where the line would cross the y axis. Now that you know all the parts to the slope you can put it together giving you the answer.

X=-2.<br> ㄱ<br> f(x) = 2x-2+5
Paha777 [63]

Step-by-step explanation:

from,

f (x) = 2x-2+5

BUT x=-2

f (x) = 2 (-2)-2+5

= -4-2+5

= -6+5

= -1

so,

f (x) = -1
