Answer:

Step-by-step explanation:

Notice that the inputs {5, -8, -1, -5} are all different. So we can immediately conclude that this is a function.

If the inputs were {5, -8, -1, 5}, this would not be a function, as the same input value (5) would result in two different outputs.

Answer:

x = 10
y ≈ 8.7

Step-by-step explanation:

Corresponding sides of these triangles are proportional, so you have ...

x/5 = 20/x

x² = 5·20 . . . . . . . cross multiply

x = √100 = 10

and ...

y/15 = 5/y

y² = 15·5 . . . . . . cross multiply

y = √75 ≈ 8.7

Find the value of x. The diagram is not to scale

Svetllana [295]

Answer:B-70

Step-by-step explanation:

from the figure, In $\triangle ABC\ \text{and}\ \triangle ADE$

$\Rightarrow \dfrac{45}{45}=\dfrac{24}{24}\\\Rightarrow \dfrac{1}{1}=\dfrac{1}{1}$

$\therefore \text{two triangles are similar}$

Thus we can write

$\Rightarrow \dfrac{35}{x}=\dfrac{45}{45+45}\\\\\Rightarrow x=35\times \dfrac{90}{45}=35\times 2=70$
