30% = 30/100 = 3/10.
3/10 of 150000 is
45000. :)
Multiplicative inverse makes the numver 1 so it multiplies by 1 which cancles the number
examle
1/3x=10
to make 1/3 into 1
we multiplyu it by its mutlipcative invers which is 3/1
1/3 times 3/1=3/3=1
1/3x times 3/1=3/1 times 10
1x=30
additive inverse makes the number 0 to cancel it out
so example
x+3=10
add the inverse of 3 to make it 0
inverse of 3 is -3
3+-3=0
so x+3-3=10-3
x+0=7
x=7
Answer:
y=5x+10
Step-by-step explanation:
The slope of the equation is caused by a rate of change. The only factor changing in this situation is the amount of money he earns per hour, (5 dollars).making 5 your slope. your y intercept is the one time fee (not changing by any increment of time) making 10 your why intercept. Then you just plug those values into the following equation, y=mx+b, where m is your slope and b is your y intercept.
<u>Answer:
</u>
Billy Bob’s farm is 80 m north of his house. The farms pond is 120 m west of the house. So the distance between the pond and the farm is 144.42 m.
<u>
Solution:
</u>
From question, given that billy bob’s farm is 80 m north of his house and pond is 120 m west of the house.
The given can be represented using the diagram given below:
where,
“a” indicates the distance between the house and the pond
“b” indicates the distance between the house and the farm
“c” indicates the distance between the farm and the pond.
For a right angled triangle, by Pythagoras theorem,
= 20800
Taking square root on both sides, we get
= 144.22 m
Hence the distance between the pond and farm is 144.22 m
Answer:
(x,y) becomes (-y,x) so (3,2) would become (-2,3)
