Answer:

all are functions except Relation 2

Step-by-step explanation:

If any input value (first of an ordered pair) is used more than once, the relation is not a function. Output values can be used as often as you like.

Only Relation 2 is not a function.

We choose the coordinates (4,4), (4,10), and (8,4) as the vertices of right-angle triangle ABC

We want to dilate triangle ABC by scale factor of 2 at the center (0,2)

The image is shown below as triangle A'B'C' with coordinates (8.6), (8,18), and (18,6).

Triangle ABC has a base of 4 units and a height of 6 units
Triangle A'B'C' has a base of 8 units and a height of 12 units

Applying Pythagoras theorem to triangle ABC to find the hypotenuse
$BC^{2}= AB^{2}+ AC^{2}$
$BC^{2}= 4^{2}+ 6^{2}$
$BC^{2} =52$
$BC=2 \sqrt{13}$

Now, we calculate the hypotenuse of the image
$B'C'^{2}= A'B'^{2}+ A'C'^{2}$
$B'C'^{2}= 8^{2}+ 12^{2}$
$B'C'^{2}=208$
$B'C'= \sqrt{208} =4 \sqrt{13}$

The hypotenuse of the image is twice the hypotenuse of triangle ABC which proof the two shapes are similar shape

2. What is an equation line that pass-cs through the point (3,-1) and h (4)

joja [24]

Y=mx+b
m=slope
b=y intercept
we are given (3,-1)
one solution is x=3 and y=-1 or
when x=3 then y=-1
also slope=2
so
y=2x+b
subsitue 3 for x and -1 for y and solve for b
-1=2(3)+b
-1=6+b
subtract 6
-7=b

y=2x-7 is equation

answer is number 4

about 0.4 of a biology class will be going on a field trip . write the decimal as a fraction in simplest form .

Ilia_Sergeevich [38]

0.4 is $\frac{4}{10}$ and that simplified is $\frac{2}{5}$ because you take the GCF or Greatest Common Factor, which is two, and divide both parts of the fraction taking $\frac{4}{10}$ and turning it into $\frac{2}{5}$
