Hey there!!!
Remember :
===> n⁻ˣ is equal to 1 / nˣ
In the question, it is stated n as 6 and x is 3
====> 6⁻³
... 1 / 6³
= 1 / 216
Hope my answer helps!
Answer:
True
Step-by-step explanation:
This is because, for the figures to be congruent, it means that, all the shape of one figure happens to be same with the shape of the other figure even though the size of the figures might be different.
Answer:
(-2,1)
Step-by-step explanation:
Since this is an upwards opening parabola, the minimum point is at the vertex
We can find the x coordinate of the vertex by
y = 2x^2 +8x +9
where a=2 b =8 and c =9
x = -b/2a
x = -8/(2*2)
= -8/4 = -2
The x coordinate is -2
Now substitute this in to find the y coordinate
y = 2(-2)^2 +8(-2)+9
= 2*4 -16+9
8-16+9
=1
The vertex = (-2,1), which is the minimum point
Answer:
The value of k is 0.8
Step-by-step explanation:
we have

This linear equation represent a direct variation
we have
y=1.2, x=1.5
substitute in the equation

solve for k
divided by 1.5 both sides

The linear equation is

163-x=-52
first subtract 163 and you get -215
now it looks like -x=-215
then the negative signs cancel out and its now x=215
