Recall that, to get the inverse relation of any expression, we start off by doing a quick switcharoo on the variables, then we solve for "y".
0.2 I believe would be the correct conversion. if not please feel free to correct me.
Answer:
32
Step-by-step explanation:
first simplify the exponent
4^2 = 16
so u would get
2 + 16 / 2 • 5 - 10
then divide and multiply to get
2 + 8 • 5 - 10
2 + 40 - 10
then add and subtract
42 - 10 = 32
Answer:
Scale factor = 2 for C
Scale factor = 2 for D
Scale factor = 2 for B
Step-by-step explanation:
Shape C has the dimensions of 2 x 6
Shape A has the dimensions of 1 x 3
Shape C is exactly 2 times an englargement of A because:
multiply 1 (dimension of A) times 2 (scale factors) = 2 (dimension of C)
multiply 3 (dimension of A) times 2 (scale factors) = 6 (dimension of C)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Shape D has the dimensions of 2 x 6
Shape A has the demensions of 1 x 3
Shape D is exactly 2 times an englargement of A because (same as C):
multiply 1 (dimension of A) times 2 (scale factors) = 2 (dimension of D)
multiply 3 (dimension of A) times 2 (scale factors) = 6 (dimension of D)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Shape B has the dimensions of 3 x 9
Shape A has the demensions of 1 x 3
Shape B is exactly 3 times an englargement of A because:
multiply 1 (dimension of A) times 3 (scale factors) = 3 (dimension of B)
multiply 3 (dimension of A) times 3 (scale factors) = 9 (dimension of B)
Isolate
y on the left side:
- Move 4
x to the right side
- Then divide the entire equation by 5
This gives you:
y = -

x - 3
This gives you the equation in the familiar (y = ax + b) format. Graph this by finding your intercepts.
- Crosses the y-axis when you put 0 in for
x --> y = -3
- Crosses the x-axis when you put 0 in for
y --> x = -

Then just draw your straight line through both points.
