answer is 4 because negative symbols are going to be positive.
Answer:
x = 8
Step-by-step explanation:
-4 + 8x = 6x + 12
Subtract 6x from both sides
-4 + 2x = 12
add 4 to both sides
2x = 16
x = 8

D = d + Vt,
d = 1.0 miles,
V = -70 miles per hour,(- because its coming towards you)
And about D
Imagine you're standing at the centre of the street. a car is coming towards you. You can easily see that car will be X miles away from you two times. When Driving towards you And When Driving away from you. So
we have two D. + 0.15 miles and -0.15 miles.
0.15= 1 - 70t
-0.15=1-70t
From here
t equals
either
0.85/70 hours which is 0.85/70*3600 second about 43.7 sec.
or
1.15/70 hours or 1.15*3600/70 about 59 sec.
Answer:
x = -1
Step-by-step explanation:
3(x+2)=−5−2(x−3) multiply 3 and -2 with inside the parenthesis
3x + 6 = -5 -2x + 6 now add the like terms
3x + 2x = 1 - 6
5x = -5 simplify both sides
x = -1
Given two endpoints:
and
, the midpoint of the two endpoints
is given by
Thus, given the midpoint L(-1, 8) and one endpoint J(4, -15). The second endpont is given by
i.e.
and
