You can set the y values equal to each other and solve the system:
x^2+3x-4=2x+2
x^2+x-6=0
(x+3)(x-2)=0
x=-3,2
So, these are the x values of the intersection. To get the y values, you can just plug them back into either formula:
y=2(-3)+2
y=-4
y2(2)+2
y=6
So the coordinates are (-3,-4) and 2,6).
1st half life: 195/2 = 97.5 g
2nd half life: 97.5/2 = 48.75 g
3rd half life: 48.7/2 = 24.375 g
4th half life: 24.375/2 = 12.1875 g
5th half life: 12.1875/2 = 6.09375 g
or you can do
195(2)^(-5) = 6.09375
** rounded to nearest gram = 6 g
Answer:
x = 0
y = -4
negative 4 cuz the line goes down, meaning it's negative
Answer:
A- $3500
Step-by-step explanation:
The depreciation rate is $300
$5000, $4700, $4400
$300 x 3 = 900
$4400 - 900 =
$3500.
Answer:
use the formula A = 1/2bh, where A = area, b = base, and h = height. Once you have the areas of all sides and faces, you simply add them together to get the surface area.
Hope this helps!
