Answer:
x = -8
y = 6
Step-by-step explanation:
x + 2y = 4
-x - y = 2
-8 + 2(6) = 4
-(-8) - 6 = 2
-8 + 12 = 4
8 - 6 = 2
Answer:
Step-by-step explanation:
Objective:Functions
The table of values range and domain isn't proportional so the answer is exponential.
A exponential function is represented by
The y values are decreasing by a common ratio of 4 so our b(our base) cant be negative so it will be
b=1/4 so plug that in our expression.
Let plug in 1,512.
So our function is
Answer:P: the principal, the amount invested
A: the new balance
t: the time
r: the rate, (in decimal form)
Ex1: If $1000 is invested now with simple interest of 8% per year. Find the new amount after two years.
P = $1000, t = 2 years, r = 0.08.
A = 1000(1+0.08(2)) = 1000(1.16) = 1160

How do you calculate the mass of a solid copper cuboid with a density of 9.86 g/cm^3. The dimensions of the cuboid are 10 cm by 3 cm by 5 cm
step 1
Find the volume of the cuboid
step 2
Find the mass
we know that
To find out the mass multiply the density of the solid by its volume
so
