what is the slope of the line graphed below? (3,3) (0,-6)

Answers

Answer:

Where is the line

Step-by-step explanation:

Answer:

The slope of the lines is 3.

Step-by-step explanation:

Since I can't actually graph it, we can make a table

x      y

3      3

0     -6

From 3 to -6, you subtract 9 (for the y section)

From 3 to 0, you subtract 3 (for the x section)

Now all you need to do is divide y by x

y/x = -9/-3 = 3

It's a positive 3, because two negatives times each other will always result in a positive.

Slope = 3

Hope this helped!

(-s - 5) + (-2s + 2)

Answers

Answer:

-3s - 3

Step-by-step explanation:

Using PEMDAS you first want to get rid of the parenthesis, but in this case you don't have to change signs or anything because you're simply adding what's in the second parenthesis. From that you want to simplify by combining like terms.

= -s - 5 - 2s + 2

= -3s -3

Answer:

How do I do this!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

x = 5

Step-by-step explanation:

39° + 90° + (7x + 16)° = 180°

39 + 90 = 129

180 - 129 = 51

7x + 16 = 51

7x + 16 - 16 = 51 - 16

7x = 35

7x/7 = 35/7

x = 5

what is the other endpoint of a segment with one endpoint at(-3, 8) and the midpoint at (7, 1)?​

Answers

Answer: The other point is (17, -6).

Step-by-step explanation:

Midpoint (x,y) of the line segment joining (a,b) and (c,d) is given by :-

[tex](x,y) =(\dfrac{a+c}{2}, \dfrac{b+d}{2})[/tex]

Here, we need to find the other endpoint of a segment with one endpoint at(-3, 8) and the midpoint at (7, 1).

Let other point be (a,b), then

[tex](7,1)=(\dfrac{-3+a}{2},\dfrac{8+b}{2})\\\\\Rightarrow\ \dfrac{-3+a}{2}=7\ \text{ and }\dfrac{8+b}{2}=1\\\\\Rightarrow\ -3+a = 7\times2 \text{ and } 8+b=1\times2\\\\\Rightarrow\ -3+a=14\text{ and }8+b=2\\\\\Rightarrow\ a=14+3, \ \ \ b= 2-8\\\\\Rightarrow\ a=17, b= -6[/tex]

hence, the other point is (17, -6).

Which is the graph of y= 3/4x - 3?

Answers

The answer is Graph A.

The equation is written in slope-intercept form y=mx+b, so the slope m is 3/4, and the y-intercept is -3.

You can immediately eliminate graph B because its y-intercept is 3, not -3.

Then, you can count the rise/run for the other two graphs to see which one has a rise/run of 3/4. That’s graph A (graph C has a rise/run of 3/2, so it’s wrong).

Suppose you are trying to find your longitude

and start looking for when the shadows are

shortest at your house. You discover that this

happens at 1:15:23 p.m. EDT (Eastern Daylight

Savings Time). What is the time in GMT?

Remember that EDT = GMT - 4.

Answers

Answer: 5:15:23 pm

Step-by-step explanation:

There are different time zones in the world due to the Earth's rotation as this results in different parts of the Earth receiving sunlight at different times.

GMT is used as a basis to find the times of other zones.

In this instance, EDT time is -4 that of GMT.

This means that EDT is 4 hours behind GMT.

Time in GMT is therefore:

=  1:15:23 + 4 hours

= 5:15:23 pm
