Answer:
A and D
Step-by-step explanation:
We are given that
(3/4,2/3),(1/4,1),(1,1/2) and (1/2,1)
k=
Direct proportion:
Inverse proportion:
Therefore, it is not in direct proportion.
Therefore, 
Hence, the given points form an inverse variation .
Option A and D is true.
<span>A)2x^2+3 is a transformation of f(x)=x^2: Stretch the graph vertically by a factor of 2 and then shift the entire resulting graph up by 3 units. The graph will still look like a parabola that opens up.
</span>B)-2x^2-3 is a transformation of f(x)=x^2: Stretch the graph vertically by a factor of 2, reflect the resulting graph in the x-axis, and then shift the entire resulting graph down by 3 units. The graph will still look like a parabola that opens down.

Answers to C and D are very similar, except that we compress the graph of x^2 v ertically by a factor of (1/2).
None of these A, B, C, D is wrong.

Slope formula;
m = y2 - y1/ x2 - x1 point(x, y) = (4, 1), (7, -2)
m = -2 - 1/ 7 - 4
m = -3/3
m = -1
the slope is -1.
hope this helps, God bless!
Distributive property lets you distribute 3(3+x)
so this is the property, note: xy=x times y=x(y)
a(b+c)=(ab)+(ac)
Answer:
x=17/3
Step-by-step explanation:
divide both sides by 3 to isolate x
