Answer:
no solution
Step-by-step explanation:
use grouping method:
f(x) = x^2 - 4x + 2
factor it:
when we try to factor the above equation, we see that there is no ordered pair in which the numbers multiple to -4 and add to 2, so there is no solution

Answer:
-10x + 6y + 2z = -30 10x + 2y + 8z = 18 8y + 10z = -12 4y + 5z = -6 -15x + 9y + 3z = -45 15x + 5y + 7z = 9 14y + 10z = -36 7y + 5z = -18 7y + 5z = -18 -4y - 5z = 6 8x-9y=72. 8x−9y=72 8 x - 9 y = 72. 3y - 3y x?+6x=2x-4 x²+4X=-4 x2+4x +4= 0. (x+2)(x+2) =0. X=-2 x=-2 ... 6-3x = 4x + 4. . 2=7x -. - 4-2=34+12. - ý 2=2y+12. +. 3X= 12-X.

Answer:
Step-by-step explanation:
This is about sums.
Use the numbers in the table to find respective sums.
1. Sum of all fi
- ∑fi = 3 + 5 + 7 + 8 + 12 + 10 = 45
2. Sum of all xi
- ∑xi = -2 + 5 + 4 - 3 + 7 + 6 = 17
3. Sum of all yi
- ∑yi = 3 + 3 - 7 + 2 - 5 - 1 = - 5
4. Sum of fi*xi
- ∑(2 to 4)fi*xi = 5*5 + 7*4 + 8*(-3) = 29
5. Sum of (xi + yi)
- ∑(1 to 3)(xi + yi) = (-2 + 3) + (5 + 3) + (4 - 7) = 6
Answer:
y=1/6x
Step-by-step explanation:
Given that y= # of pushups and x = time, you can do 4 pushups in 24 seconds
therefore, 6y=x
In otherwords, y=1/6x
