Answer:
Approximately $594.38
Step-by-step explanation:
Use the formula: y = a(1 + r)^t
a is the initial amount
r is the percent of interest in decimal form
t is the time in years
y is the money after t years
Substitute the values given in the problem into the equation:
400(1+0.02)^20
Use a calculator or solve manually
Around 594.38
(x/8)+(1/2)=7/8
X/8=7/8-1/2
X/8=7/8-4/8
X/8=3/8
X=3
Answer:
C. 10
Step-by-step explanation:
Slope / Gradient: (y - y¹) / (x - x¹)
Using points (-20, 0) and (-10, 1)
= [-20 - (-10)] / [0 - 1]
= -10 / -1
= 10
Solve like a linear algebra equation
use for slope
the b is intersept
