Basically that’s all it is to find the linear equation it’s that or y=mx+b either way you’ll find the slope
Answer:
9
Step-by-step explanation: A^2+B^2=C^2
Answer:
-1/5
Step-by-step explanation:
When a line is perpendicular to another line, it's gradient will be a reciprocal.
To calculate the reciprocal of a number you have to flip the fraction the other way around.
So, in the case our current gradient is 5/1 (5/1 is the same as just 5) and we need to flip in over to get 1/5, which is our new gradient.
The final step is to make the number negative because the line is going down. This gives us the final answer of -1/5.
Step-by-step explanation:
So let's make the two numbers "X" and "Y".
X + Y = 5
That's the very first line
let's take X as the bigger number and Y as the Smaller number.
3x + 2y = 28
now we have two equations and two unknowns.
We can also arrange the first equation to be as
X = 5 - Y
substitute this equation in the 2nd equation
3(5- Y) + 2Y = 28
15 - 3Y + 2Y = 28
-Y = 13
Y = -13
Substitute Value of Y in any equation to get X
X = 5 - (-13)
X = 18
The graph of 4|x| is shaped like a V where the vertex is at the origin ( because when x = 0 y=0) All y values are positive ( because of the absolute value |x| )
Refection in the x-axis will make all the y values change from positive to negative so the answer is y = -4|x|
g(x) = -4|x|
