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:
41 people
Step-by-step explanation:
Clinton hosted an end-of-year party. He expected 5 guests, but 8 times as many showed up. How many people attended?
The amount of guest that showed up can be calculated as:
5 guest × 8 times the number of guests
= 40 guests
The number rod people that attended the end of the year party = 40 guest + Clinton
= 41 people
Answer:
4+12+8 = 24
Step-by-step explanation:
4+8=12 + 12 = 24 :)
Answer:
No x-intercept/Zero
Step-by-step explanation:
f(x)=3x(3/4)x-4
To find x-intercept/zero, substitute f(x)=0
0=3x(3/4)x-4
To raise a fraction to a power, raise the numerator and denominator to that power
0=3x 3 x-4/4 x-4
Calculate the product
0=3 x-3/4 x-4
Since the right-hand side is always positive, the statement is false for any value of x
Since there is no solution for f(x)=0, there is no x-intercept/Zero
