The expression that represents the number of days until only 10% remains is
T((d) 10%) = 100 • (1/2)^3.322
Answer:
x=-22/4
y=-3
Step-by-step explanation:
3x-2y=-5
4x+2y=-16
we <u>add</u> the equation
7y=-21
y=-3
then we find the x by taking a random equation
I take 4x+2y=-16
4x+2(-3)=-16
4x-6=-16
4x=-22
x=-22/4

Find the slope m.
m = (1 - 2)/(3 - (-1))
m = -1/(3 + 1)
m = -1/4
Use the slope and one of the points and plug into the point-slope formula.
y - 1 = (-1/4)(x - 3)
Isolate y.
y - 1 = (-1/4)x + (3/4)
y = (-1/4)x + (3/4) + 1
y = (-1/4)x + (7/4)

Step-by-step explanation:
Set up proportion 170/180=x/1 than cross multiply 170x=180 divide both sides by 170 answer 0.944 so 94% remains
