Answer:
s = -2400t + 17400
Step-by-step explanation:
Let's say t is the x value on a coordinate plane, and s is the y. Then, we have the points (0, 17400) and (6, 3000). The slope of these is 14400/-6 or -2400.
Now we just have the equation y = -2400x + b, and from the point (0, 17400) we can find that b is 17400. So, we have y = -2400x + 17400. Convert these back into t and s and you get your answer, s = -2400t + 17400.

Answer:
x = 2.4 or x = 0.3
Step-by-step explanation:
3x² - 8x + 2 = 0
Quadratic formula
x = {-b ±√b² - 4ac} / 2a
a = 3
b = -8
c = 2
x = {-b ±√b² - 4ac} / 2a
= {-(-8) ±√(-8)² - 4*3*2} / 2*3
= (8 ± √64 - 24) / 6
= (8 ± √40) / 6
= (8 ± 2√10) / 6
= 8/6 ± 2√10/6
= 4/3 ± √10 / 6
x = 4/3 + √10 / 6 or 4/3 - √10 / 6
x = 2.4 or x = 0.3
Answer:
Step-by-step explanation:
Thrice the sum of three fifths and two thirds less one half is expressed as 3(3/5 + 2/3)-1/2
Open the parenthesis
3(3/5) + 3(2/3) - 1/2
= 9/5 + 6/3 - 1/2
Find LCM
= 9(6)+10(6)-15/30
= 54+60-15/30
= 54+45/30
= 99/30
= 3 9/30
= 3 3/10
Hence the number id 3 3/10
