Answer:
(- 1, 1 )
Step-by-step explanation:
Given the 2 equations
y = 3x + 4 → (1)
y = x + 2 → (2)
Substitute y = 3x + 4 into (2)
3x + 4 = x + 2 ( subtract x from both sides )
2x + 4 = 2 ( subtract 4 from both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1
Substitute x = - 1 into either of the 2 equations and evaluate for y
Substituting x = - 1 into (2)
y = - 1 + 2 = 1
Solution is (- 1, 1 )
Answer:
B, C, D, E
Step-by-step explanation:
I just substituted the pairs in so
14 = 6(3) - 4(1)
14 = 18 - 4
14 = 14 yes that works
let's try another pair just so you see
14 = 6x - 4y
14 = 6(-1) - 4(-5)
14 = -6 - (-20)
14 = 14 yes that works
14 = 6(1) - 4(-2)
14 = 6 - (-8)
14 = 14 yes that works
14 = 6(14) - 4(-4)
14 = 84 - (-16)
14 = 100 nope
14 = 6(4) - 4(2.5)
14 = 24 - 10
14 = 14 yes that works
Answer:
3y+5
Step-by-step explanation:
You will have to distribute the negative to (y-2).
4y+3-y+2
3y+5
we have to first convert fraction of hours into minutes
1 hour is equivalent to 60 minutes
then 3/4 hour is - 3/4 of 60
when the of function is used we have to multiply the 2 numbers
then 
3/4 of an hour is equivalent to 45 minutes
then we have to add 5 hours and 45 minutes to 11.32 pm
add 5.45 to 11.32
11.32
5.45 +
-------
16.77
then its 16 hours and 77 minutes
an hour has only 60 minutes so we subtract 60 minutes from 77 minutes and add that hour to 16 hours
16 hours + 1 = 17 hours
77 minutes - 60 minutes = 17 minutes
17 hours 17 minutes
time is given in pm therefore its a 12 hour clock
so we have to subtract 12 hours from 17 hours 17 minutes
17.17 hours - 12 hours = 5.17
the new time is 5.17 am of the next day
