Step-by-step explanation:
y = mx + c, where m is the slope of the line and c is the y-intercept.
We have y = 3x - 4 as line L.
Slope of line L = 3
=> Slope of line L2 = -1/3
We have y = -1/3 x + c as our line L2 equation.
When x = 9, y = 5.
=> (5) = -1/3 * (9) + c
=> 5 = c - 3, c = 8
Hence the answer is y = -1/3 x + 8.
Answer: y = -1
Explanation: the y axis is the vertical line, the crossing line intersects at -1.

Two triangles are similar if they are the same, except one is bigger and one is smaller. Also, their angles are all the same. A career that uses similar triangles could be a mathematician, or a math teacher. Both of these need to be able to understand simple concepts like similar triangles to teach to their victims.
consider first number is = x
formula,
(n / 2)(first number + last number) = sum,
7/2(x+x+6)= 945
2x+6= 945×2/7
2x+6 = 270
2x= 270-6
x=264/2= 132
Answer the smallest number is 132.
Answer:
84
Step-by-step explanation:
Let x = the test
(x + x + ( x - 6))/3=82
((3x - 6)/3) • 3= 82 • 3
3x - 6 + 6 = 246 + 6
<u>3x</u> = <u>252</u>
3 3
x = 84
