Me i dont under stand these. i need like right now.
how many solutions are there to the following system of equations?
3x – 9y = 0
–x + 3y = –3
a. infinitely many
b.1
c.2
d.0
what is the solution to the system of equations?
2x + y= -3
x - 2y= -4
in a recent golf match, tiger’s score was 4 less than phil’s score. their combined scores totaled 140. let p represent phil's score and t represent tiger's score.
which pair of equations can be used to determine their scores?
a. p – t = 140
p + t = 4
b. p + 140 = t
p = 4
c. p + t = 140
p – t = 4
d. p + t = 140
p + t = 4
(i think this one is c)
the system of equations is coincident.
what are the missing values?
3x + y= 7
9x + __ y= __
allison and her husband noah both get in their cars and begin to drive at the same time. allison starts 360 mi from their home and drives directly home at a constant rate of 50 mph. noah starts at their home and drives away from the home at a constant rate of 40 mph. the system that models this situation is given, where d represents the distance from home, and t represents time, in hours. the solution to the system is (4, 160).
what is the correct interpretation of the solution to this system?
d = 360 - 50t
d =40t
a. noah will be 160 mi from home and allison will be 4 mi from home.
b. allison and noah will both be 160 mi from home after 4 h.
c. noah will be 4 mi from home and allison will be 160 mi from home.
d. allison and noah will both be 4 mi from home when they drive for 160 min.
me i dont understand these.
