Answer:5 + /- sqrt35
Step-by-step explanation:
Rearranging, we get x^2 -10x -10=0
Applying the quadratic formula,
(10 +/- sqrt(10^2 -4*-10))/2
(10+/- 2sqrt35) /2 = 5 + /- sqrt35 as the two roots.
Answer:
7
Step-by-step explanation:
5+2=7
Answer:
10
Step-by-step explanation:
1/4 x 4 = 1, so 4x2 is 8. Then, 1/4 x 2 = 2/4, so 2, and 8+2=10
Answer:
Undefined
Step-by-step explanation:
The formula for slope is 
So use the x's and y's from the given points to solve for the slope
(10, -6) (10, -6)


The slope for this line would be undefined because a number cannot be divided by 0
Say . . . (13 lbs)/(5/8 lbs/bag) . . . make sure units cancel . . . 13/5*8 = 20.8 bags . . . but get 21 bags just because you can't buy a fraction of a bag.
