Answer:

A Series is always a periodic sum of terms, so only A and D will apply to that definition

(where A= 1/2 + 1/4 + 1/6 + 1/16 + 3.14159 and B=25 - 5 - 10 - 15 - - 125

F(x) = 3x - 5 and g(x) = x + 3, find (1-9)(x).

snow_lady [41]

f(x)= 3x - 5 is x = 5/3

g(x) = x +3 is x = -3

(1-9)(x) is -8x

Find the point, M, that divides segment AB into a ratio of 5:2 if A is at (1, 2) and B is at (8, 16).

d1i1m1o1n [39]

Since M divides segment AB into a ratio of 5:2, we can say that M is 5/(5+2) of the length of AB. Therefore 5/7 × AB.
distance of AB = d
5/7×(x2 - x1) for the x and 5/7×(y2 - y1) for the y
5/7×(8 - 1) = 5/7 (7) = 5 for the x
and 5/7×(16 - 2) = 5/7 (14) = 10 for the y
But remember the line AB starts at A (1, 2),
so add 1 to the x: 5+1 = 6
and add 2 to the y: 10+2 = 12
Therefore the point M lies exactly at...
A) (6, 12)

Help me plzzzzzzzzz<br> solve for x

Svet_ta [14]

Answer:

$7) \frac{x+20}{x}=\frac{46}{30}$

$30(x+20)=46x$

$30x+600=46x$

$46x-30x=600$

$16x=600$

$x=75/2$

$x=37.5$

---------------------

$8) \frac{10}{3x+1} =\frac{22}{7x-1}$

$10(7x-1)=22(3x+1)$

$70x-10=66x+22$

$70x-66x=22+10$

$4x=32$

$x=\frac{32}{4}$

$x=8$

<u>---------------------</u>

hope it helps...

have a great day!!
