Ivy earns 8.5 money per hour for babysitting.
Step-by-step explanation:
The given data is linear and it clearly represents the following information:
(2,17) shows 2 hours = 17 money
(5,42.5) shows 5 hours = 42.5 money
So, to find the money for 1 hour let us assume as "X" money per hour.
Using the rate formula,
Money per Hour= Total money/Total hours
X money/1 hr= 59.5 money/7 hours
<u>X= 8.5 money/hour</u>
The answer to the question is d
Step-by-step explanation:
3)
2x + 3y = 12
Solve for y. Then you have y = mx + b, and m is the slope.
3y = -2x + 12
y = -2/3 x + 12
slope = -2/3
6x - 4y = 8
-4y = -6x + 8
y = -6/(-4) x + 8/(-4)
y = 3/2 x - 2
slope = 3/2
Since the slopes -2/3 and 3/2 are opposite reciprocals, the lines are perpendicular.
4)
3x - 4y = 12
-4y = -3x + 12
y = -3/(-4) x + 12/(-4)
y = 3/4 x - 3
slope = 3/4
4x + 3y = 15
3y = -4x + 15
y = -4/3 x + 5
slope = -4/3
Since the slopes 3/4 and -4/3 are opposite reciprocals, the lines are perpendicular.
Answer
I think Asia is the answer.
Step-by-step explanation:
A vector is defined as an object which has got some value or magnitude and has a direction as well.
The vector =(0,0) is called the zero vector because it has zero length and no direction at all. The zero vector has an undefined direction.
The zero vector behaves same as the number zero and when added to any vector say "a", we get the answer as vector "a" which remains unchanged.
