(-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
Answer:
-4.2
Step-by-step explanation:
we know the mid point formula
(x ,y)=<u>x</u><u>1</u><u>+</u><u>x</u><u>2</u> , <u>y</u><u>1</u><u>+</u><u>y</u><u>2</u>
2 2
=<u>0</u><u>+</u><u>1</u><u>0</u> , <u>6</u><u>+</u><u>0</u>
2 2
=(5,3)
centre of circle(x, y)=(5,3)
Answer:
3.33
Step-by-step explanation:
To solve for x you must divide both sides of the equation by 18. This is the DPE. Then the two 18s cancel each other out leaving u with x. Then divide 60 by 18 which then equals to 3.33. This Then gives the answer x=3.33.
Answer:
Irrational
Step-by-step explanation:
This answer will always irrational because for example if have 2 square root 3+4 then it would be irrational if you add them together because you wouldn’t be able to put that in a fraction
