(10x+21) + (13x) = 90
23x + 21 = 90
-21 -21
23x = 69
/23 /23
x = 3

10(3) + 21
30 + 21 = 51
FEH = 51

13(3) = 39
DEH =39

Trava [24]

Hi,

Answer: B) 25.82%

<u>My work:</u> For this problem you can easily achieve this problem (Preferably with a caculator) by taking the date’s 2014 and 1969 the time of growth and subtract them. When you do this you get the answer 45. From there you you take 45 (With caculator) and multiply it with 25.82 % (To do this you take 25.82 and press 2nd, then the percent). When you do this you get 11.619 which rounded is 12; furthermore, which is your answer.

I Hope I Helped!

Determine whether b is in the column space of A. If it is, then write b as a linear combination of the column vectors of A. (Use
mihalych1998 [28]

Answer:

b=(13/4, -27/4, -4)

Step-by-step explanation:

A.x=b

x=(a, b, c)

a   - b + 2c = 2

3a + b +  0 = 3

0  + 0 +  c = -4

solving this system

c=-4

a-b=10, 3a+b=3

a=10+b, 3(10+b)+b=3

b=-27/4

a=10-27/4

a=13/4

For each linear equation write the slope of a line parallel to the given line. 3x - 2y = 8 ​
PSYCHO15rus [73]

We first need to convert 3x - 2y = 8 into y = mx + b form.

To do this, we first subtract 3x from

both sides and we have -2y = -3x + 8.

Now divide both sides by -2 and we have y = 3/2x - 4.

Now, we want the slope parallel to this given line.

Since the m or the coefficient of the x term

represents slope, we know this line has a slope of 3/2.

Now, it's important to understand that parallel lines have the same slope.

So the slope of the line parallel to this line will also be 3/2.
