....
(-3, 1) y = 2/5x - 4
x₁ y₁ slope (m) = 2/5x
Since the equation we are looking for is perpendicular to y = 2/5x - 4, we need to find the opposite reciprocal slope. We have to flip the slope upside down and turn it negative.
2/5 ⇒ 5/2 ⇒ -5/2
So far, we have the equation y = -5/2.
Now, we need to find the y intercept by plugging in the given point into point slope form, which is...
y - y₁ = m(x - x₁)
The subscripts in the y and x are just the x and y in (-3,1). They are just placeholders, not exponents.
y - 1 = -5/2(x + 3)
y - 1 = -5/2x - 15/2
+ 1 + 1
------------------------------
y = -5/2x - 13/2 ⇒ final equation
The two equations represent parallel
When put into y=mx+b form, they both result in the equation y= -4/5x + 4/5
This causes them to overlap, meaning that they are parallel to one another.
Answer:
12.5
Step-by-step explanation:
(3+8)/2 = 5.5
5.5 + 7 = 12.5
X + y = 125
x - y = 47
---------------add
2x = 172
x = 172/2
x = 86
x + y = 125
86 + y = 125
y = 125 - 86
y = 39
ur 2 numbers are 39 and 86
