i think its -9118 sorry if im wrong
Answer:
5y = -2x + 31
Step-by-step explanation:
Given equation:
y =
Coordinate = (-7,9)
Unknown:
Equation of the line perpendicular = ?
Solution:
The slope - intercept format of a line is given as;
y = mx + c
where y and x are the coordinates
m is the slope
c is the y-intercept
y =
From the given equation; slope is
A line perpendicular will have a slope that is negative and the inverse of this;
slope of perpendicular line =
Since y= 9 and x = -7;
So;
9 = + C
9 = + C
C = 9 - =
Now,
y = x +
mulitply through by 5;
5y = -2x + 31
32.45 is most precise . Precise means how many points after decimal is reached. Accurate means how close your measurement of a value is that to the true value. Eg :Say 35cm is the measure of length of a body and a person got the measurement to be 34 . Another person2 got the measurement to be 32.88 . So in this case the first person has an accurate answer as he is close to the true value 35 , but person2 is more precise as he has two decimal places.
Step-by-step explanation:
The number of subsets=2ⁿ where n=4 members
2ⁿ=2⁴=16
Number of proper subsets=2ⁿ-1
16-1=15
Option B
Because you would not make as much money
