I believe if b were to equal the value of 0, there would be 2 solutions to the function. Or not mainly if the resulting expression turns out to be a difference of squares.
Eg. f(x) = 2x^2 + 0x + 2
2x^2 + 2
2(x^2 + 1)
Here there would not be x intercepts, mainly because x cannot be solved.
The answer would be B. Only 3.
An object has a line of symmetry when it is cut a certain way and both parts are identical. Only line 3 will give you two identical halves when cut in that way.
Answer:
= -48
Step-by-step explanation:
3x^3 - 8y^2
3 ( 2 )^3 - 8 ( -3 )^2
first you solve the exponents
3 ( 8 ) - 8 ( 9 )
multiply
24 - 72
subtract
= - 48
hope this helps
Step-by-step explanation:
To find the equation you must first find the gradient and also look for the points on the graph.
I see point ( 0, 2) and point (4, 1)
Hence first find the gradient before equation
the gradient = y2-y1/x2-x1
y2 = 1
y1 = 2
x2 = 4
X1 =0
if you put in the values it will look like
1-2/4-0
-1/4
the gradient = -1/4
So for the equation the formula is
remember m is the gradient
y - y1 = m ( x - x1 )
so put in the value from only one point so you can choose either (0,2 ) or (4,1 )
I will go with (4, 1)
y - y1 = m ( x - x1 )
y - 1 = m ( x - 4 )
y -1 = -1/4 ( x - 4)
4 ( y-1) = -1(x-4)
4y- 4 = -1x +4
4y - 4 -4 = -1x
4y -8= -1x
4y + 1x -8 = 0
this is the equation.
thanks and good luck.
