THE ANSWER IS B BECAUSE I TOOK THIS QUIZ ALREADY
Answer:
A
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 (h, k) = (2, 1), thus
y = a(x - 2)² + 1
To find a substitute (1, 0) into the equation
0 = a(1 - 2)² + 1
0 = a + 1 ( subtract 1 from both sides )
a = - 1
Hence
y = - (x - 2)² + 1 or
y = 1 - (x - 2)² → A
If you switch it around, it'll be: 1,707 - 264
Subtract:
1,707 - 264 = 1443
Answer = 1,443
~Hope this helped~
3(6-7x)=-(x+2)
Use distributive property
18-21x = -x -2
Add x on both sides
18-20x = -2
Subtract 18 from both sodes
-20x= -20
Divide
Final Answer: x=1
