Answer:
You get an perpendicular line through given point.
Step-by-step explanation:
In this method of drawing perpendicular line through given point,
you will draw an arc from given point R, so as to cut given line at A and B.
now ,length RA will be equal to length RB (radius of circle)
now, with length RA you will place compass at A and B to cut the arcs at point P (let) on other side of given line.Now, join PA and PB.
The closed RAPB makes a rhombus and diagonal bisect perpendicularly in rhombus.
so you get an perpendicular line through given point.
Answer: -2/7
|3x - 2| - 4x = 4
1) (3х - 2) - 4х = 4, if 3x - 2 >= 0
2) -(3x - 2) - 4x = 4, if 3x - 2 < 0
1)
3х - 4х = 4 + 2
-x = 6
x = -6
3х - 2 >= 0
3х >= 2
x >= 2/3 - wrong
2)
-3х + 2 - 4х = 4
-7х = 2
x = -2/7
3x-2<0
3x<2
3(-2/7)<2-right
Answer:
2-9=x
HOW
let the number be x
then 2 less than product 9
so
2-9
and a number
we don,t know number so take it x
so 2-9=x
Answer:
12.5%
Step-by-step explanation:
27-24=3
3/24=1/8
1/8=0.125
0.125 in percent is 12.5%
Answer:
Or if you want with the value of h too.
Step-by-step explanation:
Find the value of h and k by using the formula.
From y = x²-2
Substitute these values in the formula.
Therefore, h = 0.
Therefore, k = - 2.
From the vertex form, the vertex is at (h, k) = (0,-2). Substitute h = 0, a = 1 and k = -2 in the equation.
These type of equation where b = 0 can also be both standard and vertex form.
