The correct option regarding whether the graph shows a function is given by:

C. Yes; the graph passes the vertical line test.

<h3>When does a graph show a function?</h3>

In a function, one value of the input can be related to only one value of the output. Hence, in a graph, it means that for each value of x(horizontal axis), there can only be one respective value of y(vertical axis), which will mean that the graph will pass the vertical line test.

In this problem, the condition is respected, hence option C is correct.

The distance between the two points rounding to the nearest tenth<br> (-8,-6) and (-3,-4)

Lesechka [4]

Answer:

5.4

Step-by-step explanation:

To find the distance between two points, $(x_1,y_1)$ and $(x_2,y_2)$ , plug them into the following equation:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(-3-(-8))^2+(-4-(-6))^2}$

Two negatives make a positive

$d=\sqrt{(-3+8)^2+(-4+6)^2}\\d=\sqrt{(5)^2+(2)^2}\\d=\sqrt{25+4}\\d=\sqrt{29}\\d=5.4$

Therefore, the distance between the two points rounded to the nearest tenth is 5.4.

I hope this helps!

Sati [7]

Answer:

B. $60x^8$

Step-by-step explanation:

$4x^2\sqrt{5x^4} \cdot 3\sqrt{5x^8} =$

$= 4x^2 \times 3 \sqrt{5x^4 \times 5x^8}$

$= 12x^2 \sqrt{25x^{4+8}}$

$= 12x^2 \sqrt{25} \sqrt{x^{12}}$

$= 12x^2 \times 5 \times x^6$

$= 60x^8$

I need help with this problem! Must explain why.

OLEGan [10]

Answer:

95°

Step-by-step explanation:

Angle 1 and 4 are opposite angles, thus equal, so:

3x+10 = 4x-15 =>

x = 25

Angle 1 and 4 are 85°

Angle 4 and angle 6 are called allied (or co-interior) angles, which are supplementary, i.e., angle 6 = 180 - angle 4, so angle 6 = 95°.

Angle 6 and 7 are again opposite, so angle 7 is 95° as well!
