8^1/3
8 is 2^3 so 8^1/3 = 2
The other expresssions don't give whole numbers.
Answer:
Slope of the line is 
.
Step-by-step explanation:
Given points are:
(10, 3) and (7, 11)
Here,
x1 = 10 and y1 = 3
x2 = 7 and y2 = 11
Slope of a line is given by
Therefore,
Slope of the line is .
Answer:
1 because it is on the right side of the number line
Step-by-step explanation:
Answer:
x = 5
Step-by-step explanation:
Simplify the like terms:
15x - 8x = 7x
so, 7x = 35
divide: 35/7 = 5
x=5
The amount invested in each company is :
- Amount invested in PP = $2400
- Amount invested in TT = $(10000 - 2400) = $7600
Using the simple interest relation:
Simple interest = principal × rate × time
Total amount = 10000
Let :
principal invested in PP = r
HENCE, amount invested in TT = 10000 - r
Total interest earned on both investments = $620
PP investment return + TT investment return = 620
(r × 10% × 1) + (10000 - r × 5% × 1) = 620
0.1r + 500 - 0.05r = 620
0.05r = 620 - 500
0.05r = 120
r = 120 / 0.05
r = 2400
Hence,
Amount invested in PP = $2400
Amount invested in TT = $(10000 - 2400) = $7600
