Answer:
y=-4x+5
Step-by-step explanation:
divide 15 by 3 to get rid of 3y
4x+y=5
subtract 4x
y=5-4x
thats the slope!
you could turn it around too and do y=-4x+5, but it doesnt matter
6 1/4. So essentially, 6hrs and 15mins.
Answer:
part a - 122.39
part b - 91.79
Step-by-step explanation:
b)
|2x−3y| if x=0.5; y=−0.7
Substitute: |2(0.5)-3(-0.7)|
Simplify: |1+2.1|
Simplify: |3.1|
Since it is an absolute value, it will always be positive: 3.1
d)
|−3 |x| +2x−1| if x=−5
Substitute: |-3(|-5|)+2(-5)-1|
Absolute value is positive: |-3(5)+5(-5)-1|
Simplify: |-15-25-1|
Simplify: |-41|
Absolute value always positive: 41
2ft=30yd, you need to find when ft=1, 30/2=15
15+30=45
