GREYUIT [131]3 years ago
7 0
1 / 343
This is just equal to 
1 / 7^3 = 7^-3

A. 7^-1 * 7^-2 = 7^(-1 + -2) = 7^-3
B. 7^7 * 7^-10 = 7^( 7+ -10) = 7^-3
C. 7^-2 * 7^-5 = 7^(-2 + -5) = 7^-7
D. 7^-5 * 7^2 = 7^(-5 + 2) = 7^-3

So the correct answer is letter C. 7^-2 * 7^-5

Answer:

Choice 1

Step-by-step explanation:

Let‘s go through each answer and analyze a

each.

<u><em>Choice 1</em></u>

<u>Parallel</u> means to lines with the same slope, they never intersect, ever, they always remain next to each other and never touch. This is true for the picture

<u><em>Choice 2</em></u>

<u>Perpendicular</u> means that two lines intersect at a right angle, however upon looking at the picture you can see this is not a right angle, but an acute angle. So it is not perpendicular.

<u><em>Choice 3</em></u>

A <u>Line Segment </u>means a line with dots on either end, symbolizing the end of the line. This is not a line segment because there are arrows on the ends, indicating these lines go on forever. This is not a segment

<u><em>Choice 4</em></u>

We already determined this is neither a segment nor perpendicular so it cannot be this choice

This leaves us with Choice 1.

I hope this helps!

Please give thanks and brainliest!

Travka [436]

Answer:

Ok its pretty straight forward

So for every x its 1

And every y its 4/5

To make life simpler lets just make 4/5 into a whole number

So we can make it into 20/5 which equals 4

To get to 20/5 we multiply 4/5 by 5

So we multiply the x by 5 too

We’d get (5,5)

So you can plot that

And the lines should automatically plug in a different point

You can plug it into negatives

-5, -5

so something between those lines

Like i dontt get how lines work here it Make sure its on the 5,5

I can’t think of an equation but I guess

5=m5

In the Format  Y=mx (yes no y intercept because its a direct proportion formula)

Or you can use the format

y/x=m

5/5=m

Or if they suggest it in a y intercept formula

y-mx+b

just plug in like y with 5 and the x with 5.

You can also use the plot (10,8) still works :)

If I’m worng I’m sorry the question is weird and I’m assuming they asking you about Proportional/direct relationships
