1.
u^-3 = 1/125
1/u^3 = 1/125
u^3 = 125
u = 5
2.
y-1 = 4y - 2/3
each term times 3
3y - 3 = 12y - 2
-9y = 1
y = -1/9
3. your are right
4.
number of miles last week --- x
x+40 = 4x + 10
-3x = -30
x = 10
She ran 10 miles last week
5. change it into the form y = mx + b
(takes 2 steps)
4y - 6x + 12 = 0
4y = 6x - 12
y = (6/4) - 12/4
y = (3/2)x - 3
*not multiple choice*
u^-3 = 1/125
y - 1 = 4y - 2/3 * not sure how to do
this
what is the y intercept of the line?
y= -3x - 5 * my answer is 5
when 40 is added to the number miles she ran last week..the result is the same as adding 10 to 4 times the number she ran last week. * not sure how to do this, because I have to find the miles she ran last week.
what is the slope of the line 4y - 6x + 12 = 0 in simplest form? * not sure how to do this
