Based on the sequence, it shows an Arithmetic Sequence. The difference from one number to the other is 0.75. In order to get the sum of the sequence at a given N items, you need to use the formula. 

The formula is S = N/2 [2a1 + (N-1)d].
S = sum
N = number of items
a1 = first item of the sequence
d = difference from one item to the next item

Mutleys journey began on a boat, 2 feet above sea level. He dove down to twelve feet below sea level and then returned to the su
Lubov Fominskaja [6]

Answer:

Mutley would start at 2 feet above sea level or +2, he would then travel 12 feet below sea level (-12) to then return to the surface of the ocean (0).  The integers from least to greatest:  -12, 0, 2.  Visual:

-12(dive level) * * * * * * * * * * * 0(sea level) * 2(boat)

Step-by-step explanation:

Using positive and negative integers, we can determine Mutleys journey above, below and at the surface of the ocean.  The surface of the ocean represents his 'origin' or starting point, which is 0.  The boat is above the surface or +2.  When Mutley dives below the surface, he is at a negative level of the ocean.  Think of it in terms of a number line - negative numbers are to the left of 0 and positive numbers are to the right of 0.  The further we go to the left on the number line, the lower our number.  In this case, -12 would be furthest to the left, then 0, followed by 2.

Answer:

5.498 - C

Step-by-step explanation:

Length of an arc = tetha/360 × 2 × pi × r

Converting 7pi/4 to tetha

(7 × 180) / 4 = 315°, since pi = 180°

Plugging values to the formula:

315/360 × 2 × 3.142 × 1 = 5.498units

What is the slope intercept form of 10x + 2y =8
antoniya [11.8K]

Slope intercept form is: y = mx + b


Isolate the y. First subtract 10x from both sides


10x (-10x) + 2y = 8 (-10x)


2y = -10x + 8


Isolate the y. Divide 2 from both sides and <em>all</em> terms.


(2y)/2 = (-10x + 8)/2


y = -5x + 4


y = -5x + 4 is your slope intercept form answer.



hope this helps
