PLS HELP PLS ASAP ILL GIVE BRAINLKEST THANKS

Umnica [9.8K]

Answer:

1/2

Step-by-step explanation:

When you analyze the graph for your slope, you RISE over RUN meaning you go up/down first and then left/right next.

I got 1/2 because RISE over RUN is written the same (or is the same) as Y over X

2/4 = 1/2

3/6 = 1/2

4/8 = 1/2

5/10 = 1/2

therefore your slop must be 1/2!

hope this helpsss

A bus traveled on a level road for 3 hours at an average speed 20 miles per hour faster than it traveled on a winding road. The

BabaBlast [244]

Answer:

65 mph on level road

Step-by-step explanation:

Set b as average speed on the level road and (b-20) = average speed on the winding road

Distance = speed * time

Level Road distance + winding road dististance = 285 miles

Substituting b and (b-20), we have,

3b + 2(b-20) = 285

3b + 2b - 40 = 285

5b = 285 + 40

5b = 325

b= 325/5

b = 65 mph on level road

The measure of an angle is 103°. What is the measure of its supplementary angle?

icang [17]

Answer:

Step-by-step explanation:

Let's let the unknown number be x.

Supplementary angles add up to a total of 180 degrees. Since we already know one angle is 103, this means that:

$103+x=180$

Subtract 103 from both sides:

$x=77\textdegree$

So, the measure of its supplementary angle is 77 degrees.

And we are done!

Fill in the blanks to make an arithmetic sequence

Arlecino [84]

-----------------------------------------
General Equation:
-----------------------------------------
$T_n = a_1 + d(n - 1)$

-----------------------------------------
Find d :
-----------------------------------------
$a_1 = 11, T_7 = 79,$
$T_7 = 11 + d(7 - 1)$
$-79 = 11 + 6d$
$6d = -79 - 11$
$6d = -90$
$d = -15$

-----------------------------------------
Find general equation :
-----------------------------------------
$T_n = 11 + (-15)(n - 1)$
$T_n = 11 -15n + 15$
$T_n = 26 -15n$

-----------------------------------------
Find the sequence :
-----------------------------------------
$T_1 = 26 - 15(1) = 11$
$T_2 = 26 - 15(2) = -4$
$T_3 = 26 - 15(3) = -19$
$T_4 = 26 - 15(4) = -34$
$T_5 = 26 - 15(5) = -49$
$T_6 = 26 - 15(6) = -64$
$T_7 = 26 - 15(7) = -79$

---------------------------------------------------------
Answer: 11, -4, -19, -34, -49, -64, -79
---------------------------------------------------------
