Answer:
1. (7,-9)
2. (4,0) and (10,0)
3. (3,0) and (-3,0)
4. (0,-9)
5. (-1,-32)
Step-by-step explanation:
To find the vertex use the formula
First make the equation into a quadratic equation.
Now it is in the form
Now we can substitute the values
Now we have 7 as our x value for the vertex we can substitute for y,
So the vertex for 1 is (7,-9)
To find the intercepts for 2 & 3, they basically already give it to you. You just need to find a value for x for x-4 that will equal it to 0 and another for x for x-10 that will equal it to 0.
4 is slightly different but start the same,
Here, c (9) just shows the graph move down 9, so the y intercept = 9.
5 is the same process as 1,
Vertex,
Substitute,
So the vertex is (-1,-32)
The equation of a line that passes throug the point (x1,y1) and has a sloppe of m is
y-y1=m(x-x1)
the slope of paralell lines ar the same
y=3x+2
y=mx+b
m=slope
m=3
a point is (-2,0)
slope is 3
y-0=3(x-(-2))
y=3(x+2)
y=3x+6
the equation is y=3x+6
Answer:
= x^4 y^5 / 3
Step-by-step explanation:
I got this answer = x^4 y^5 / 3
But my answer is not found directly
And I think they deliberately set up this arrangement to make us mess up
, but in your Options I think it's ( B )
300/1 or you could keep going up like 600/2, 900/3 and so on
X% means X/100
To change percent to decimal divide it with 100.
Example 75% = 75/100 = 0.75
