Consider number 17. You know that
17=9+8.
Then for negative numbers you have the same rule (with respect to sign -):
-17=(-9)+(-8).
Since (-9)+9=9+(-9)=9-9=0, you have that
-17+9=(-9)+(-8)+9=(-9+9)+(-8)=0+(-8)=-8.
Answer: -17=(-9)+(-8).
Answer:
a) In other words, the equation 3x4−8x3+2=0 has a root in [2,3]
b) x≈2.630020
Step-by-step explanation:
Answer:
y = 6/5x +2
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
5y−6x−10=0
Add 10 to each side
5y−6x−10+10=0+10
5y -6x = 10
Add 6x to each side
5y-6x+6x=6x+10
5y = 6x+10
Divide each side by 5
5y/5 = 6x/5 +10/5
y = 6/5x +2
The slope is 6/5 and the y intercept is 2
