Answer:
y = -1/2x - 1
Step-by-step explanation:
Given equation:
y = 2x - 3
Given point: (x1,y1) = (-8,3)
This is in the form of y = mx + c,
so, m1 = 2
If the lines are perpendicular then the product of their slope will be - 1 i.e.
m1 x m2 = -1
2 x m2 = -1
m2 = -1/2
Now, using one point form formula,
y - y1 = m(x - x1)
or, y - 3 = -1/2( x - (-8))
or, y-3 = -1/2(x + 8)
or, y = -1/2x - 4 + 3
or, y = -1/2x - 1
This is the required equation.
Answer:
A1=48
A2=132
A3=48
A4=132
Step-by-step explanation:
15 + 16 + 17 = 48
The answer is 48.
Answer:
The median is 6.5
Step-by-step explanation:
To find the median, first organize the numbers from least to greatest:
1, 4, 6, 6, 7, 8, 9, 10
The median is always the number in the middle, but since there are eight numbers here, there will be two numbers in the middle: 6 and 7.
To solve for this, we have to find the average of the numbers.
Add the two numbers together and then divide by 2 (we divide by 2 because we are averaging two numbers).
(6 + 7)/2
13/2
6.5
