-160
Since -(20x8) the answer would be -160
Answer:
13, 14, 15, 16
Step-by-step explanation:
Call the first number n. Then the next three consecutive numbers (assuming integers) are n + 1, n + 2, n + 3.
The mean is the total of the numbers divided by how many there are.
Simplify and multiply by 4.
The first number is 13.
The median is 14.5, halfway between the "middle" numbers 14 and 15. This is just a check; no additional equation is necessary.
y = -x + 5
Slope of this line = - 1.
Slope of the line that is perpendicular is negative reciprocal.
For example if slope= a/b, then slope of the perpendicular line = -b/a.
For our line, the slope is going to be -(-1)=1.
y=mx +b
m=1
y=x+b
We need to find b. We are going to use point (5, -1).
y = x +b
-1 = 5 + b
b= -6
So,
y= x - 6
Answer is A.
Answer:
where is the chart?
Step-by-step explanation:
Find the gradient/slope of Line A:
(3-2)÷(-1-4)
=-0.2
Therefore, the gradient/slope of line B is 5
Using the equation y-y1=m(x-x1) we can find the equation of line B
y-7=5(x-3)
y= 5x-8
Sub in a random value for y (eg. y=2)
2=5x-8
5x=10
X=2
so (2,2)
