According to Vieta's formula, if
are solutions of quadratic equation
, then:
In our case:
Range 18 function no because range subtract 25- (-5) and it has the same out put (8) repeating
Answer:
x = 18
Step-by-step explanation:
x + 36 and 3x are corresponding angles and are congruent , so
3x = x + 36 ( subtract x from both sides )
2x = 36 ( divide both sides by 2 )
x = 18
Option A is the correct answer
Step-by-step explanation:
Step 1 :
The given points are
A (4,-3.75)
B (2,-7.5)
C (7.5,-2).
We need to find which point is at the same distance from the y axis as the point (
-4, 7.5). Let P = (
-4, 7.5)
The distance of a point from the y axis is given by the x co ordinate of the point.
So here the distance of the point P from the y axis is 4. (It is placed on the negative x axis because the x co ordinate = -4.)
Step 2 :
So all points which has x co ordinate as 4 or -4 will be at the same distance from the y axis as the given point P.
From the given points A B and C, we can see that the point A has 4 as its x co ordinate.
So the point A is at the same distance from the y axis as the given point P
Step 3 :
Answer :
Option A is the correct answer
