Remove the radical by raising each side to the index of the radical. a = √ 3 , − √ 3 a=3,-3 a ≈ 1.73205080 , − 1.73205080
The slope is change in "Y" divided by the change in "x"
1-(-3)/2-(-1)
= 4/3
Standard Form
y-y1=m(x-x1)
y-(-3)=4/3(x-(-1)
y+3=4/3x+4/3
y=4/3x-5/3
Rewrite in standard form
-4/3x+y=-5/3
Can't have fractions so multiply by 3 to get rid of the denominator
-4x+3y=5
Divide by -1 to get rid of the negative sign
4x-3y=-5
Answer:
Step 1) She should have added 25 to each side
Step-by-step explanation:
Since there is a -25 in the original equation, to properly cancel it out, she should have added it to both side, not subtracted. This would ensure that the -25 on the left of the = is cancelled out.
160 km - 100%
100%+30%=130%
160*130%:100%=208 (km) - <span>the number sought</span>
True, as 93 divided by 3 is 31; a whole number :)
