Form equation
y = mx + c
y = (rise/run).x + c
y = (11-1 / 3--2)x + c
y = 2x + c
11 = 2(3) + c
Find c (y-intercept)
11 - 6 = c
c = 5
Final equation of line
y = 2x + 5
Substitute given possible x-values in to find y-values
y = 2(1) + 5 = 7 (1,7)
y = 2(2) + 5 = 9 (2,9)
Therefore d is correct
X and y vary inversely means y is inversely proportional to x, this means:
y=k/x, where k is a constant.
We are given that when x=-4, y=7/2, we replace these values to find k.
7/2=k/-4
k= (-4*7)/2=-14
So we have y=-14/x
Therefore, when x=4, y=-14/4= -7/2
Simplify the equation to n-6=4n+18
subtract 4n from both sides
n-6-4n=4n+18-4n
-3n-6=18
add 6 to both sides
-3n-6+6=18+6
-3n=24
divide both sides by -3
-3n/3=24/-3.
n=-8
hope this helps!
Answer:
D to E is apparently 104 degrees , G looks like it has the same measurements , so the unknown measurements will be 74 degrees,
