Find the sum of the first 9 terms of the sequence. Show all work for full credit.

Kamila [148]

We can see the sequence goes by decreasing 9 on each number

so the numbers are

2, -7, -16, -25, -34, -43, -52, -61, -70

so adding all these numbers we get

2-7-16-25-34-43-52-61-70

= -306

hope this helped

Write the equation of a line in point Slope form that passes through the points (-8,-3) and (2,2)

ella [17]

Answer:

The midpoint of the points (2,8) and (0,4) is given by:

(

)=(

2+0

8+4

)=(

)=(1,6)

We must must transform the standard form equation −3x+6y=5 into a slope-intercept form equation (y=mx+b) to find its slope.

−3x+6y=5 (Subtract 3x on both sides.)

6y=3x+5 (Divide both sides by 6.)

The slope of our first line is equal to

. Perpendicular lines have negative reciprocal slopes, so if the slope of one is x, the slope of the other is

The negative reciprocal of

is equal to −2, therefore, −2 is the slope of our line.

Since the equation of line passing through the midpoint (1,6), therefore, substitute the given point in the equation y=−2x+b:

6=(−2×1)+b

6=−2+b

b=6+2=8

Substitute this value for b in the equation y=−2x+b:

y=−2x+8

Hence, the equation of the line is y=−2x+8.

Dave was playing checkers with a friend. The ratio of games Dave won was 10:7. If Dave won 80 games, how many games did his frie

Mila [183]

The answer is 56! How you do this, is you take 80, and you multiply it by 7. Then you divide that answer by 10. Then you have your answer! I’m really bad at math but I do know how to do that!
