X/-7 -2 =10
x/-7 = 12
x = -84
Slope intercept form is y=mx+b so the answer is y=x+5
Answer:
1.8
Step-by-step explanation:
Your answer would be 1.8 because you would have to do 0.20x 9 and that gives you 1.8
Hope I was able to help!
Answer:
a) y=8
b) x= 9
Step-by-step explanation:
a)
y/16= 2/4
y= 16 * 1/2 (cross multiply)
y= 8
b) x/5 = 36/20
x= 5 * 36/20 (cross multiply)
x= 9
Answer:
- P = -390t +48,000
- P = 43,710 in 2003
Step-by-step explanation:
A) We are given two pairs of (t, P): (0, 48000), (8, 44880). We can use these with the 2-point form of the equation of a line:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
P = (44880 -48000)/(8 -0)(t -0) +48000
P = -3120/8t +48000
P = -390t +48000
__
B) In 2003, t = 11, so we have ...
P = -390(11) +48000 = 43710
The population in 2003 is predicted to be 43,710.
