Answer:
u can use formula whole root ,( x2-x1)²+(y2-y1)²
hope it helps...
Answer:
B
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here the vertex = (- 2, - 3 ) , then
y = a(x - (- 2))² - 3 , that is
y = a(x + 2)² - 3
To find a, substitute any point on the graph into the equation
Using the coordinates of the y- intercept (0, 5 )
5 = a(0 + 2)² - 3 ( add 3 to both sides )
8 = a(2)² = 4a ( divide both sides by 4 )
2 = a
y = 2(x + 2)² - 3 → B
You have to replace the x with the 2
f(2)= 5(2)-12
f(2)= -2
Answer:
Let do this..
Step-by-step explanation:
ABCD is a parallelogram - 1
In ∆ADC and ∆CBA
AC=AC (Common)
<DAC=<BCA (Given)
AD=CB (From 1)
Therefore, ∆ADC = ∆CBA (By SAS)
