Let b>a,
a+b=40 so we can say a=40-b
We are told that b-a=6.5, using a found above in the equation gives us:
b-(40-b)=6.5
b-40+b=6.5
2b-40=6.5
2b=46.5
b=23.25, and since a=40-b
a=40-23.25
a=16.75
So a=16.75 and b=23.25
check...
16.75+23.25=40, 40=40
23.25-16.75=6.5, 6.5=6.5
Answer:
-52.1
Step-by-step explanation:
-10/100 = -0.1
-0.1 x 20 = -2
-0.1 x 501 = -50.1
+ -2
____
-52.1
Answer:
1) b= -20
Step-by-step explanation:
You bring the variable you want to find to one side by either bringing over the second term to the other side of the equation and change its sign or if it's a fraction you multiply both sides to remove the denominator and then solve
Paralell has same slope
y=mx+b
m=slope
y=5x-1
when is the slope 5?
take the derivitive of 2e^x
f'(2e^x)=2f'(e^x)=2e^x
that is the slope
5=2e^x
divide both sides by 2
2.5=e^x
take the ln of both sides
ln2.5=x
when x=ln2.5 they are paralell
