The distance between the two points is 5 units
Explanation:
Given that the two points are located at and
We need to determine the distance between these two points using Pythagorean theorem.
The distance between the two points can be determined using the formula,
Substituting the coordinates and in the above formula, we get,
Simplifying, we get,
Squaring the terms, we get,
Adding the terms, we have,
Simplifying, we get,
Thus, the distance between the two points is 5 units.
Answer:
The solution of the two give equations is (-1,4)
Step-by-step explanation:
i) First equation is y = -x + 3
ii) Second equation is y = x + 5
iii) If we add the two equations we get 2y = 8 ∴ y = 4
iv) Substituting the value of y obtained in iii) in equation i) we get
4 = -x + 3 ∴ -x = 4 - 3 ∴ -x = 1 ∴ x = -1
v) substituting x = -1 and y = 4 in the second equation we see that the equation is satisfied.
You multiply across which would be 16 and 2 then you get y add 4 and you get the other y
Answer:
1) 2
2) y=2x+=-2
3) a=5
b=6
4) y=2x-2
y=(2*0)-2
y=0-2
y=-2
I'm not sure if they are all right
Sorry if they aren't
