it's now
[tex]a = b - a[/tex]
now plus the a to cancel out the minus a to get

Step-by-step explanation:
1.8 x 10^-2 - 3.9 x 10^-33 = 18 x 10^-3 - 3.9 x 10^-3
= (18-3.9) x 10^-3
= 14.1 x 10^-3

AB and BC form a right angle at point B. If A= (-3, -1) and B= (4, 4), what is the equation of BC
A. x + 3y = 16
B. 2x + y = 12
C. -7x - 5y = -48
D. 7x - 5y = 48
Answers
Answer:
(C) -7x - 5y = -48
Step by step explanation:
We look for the equation of the line AB
We have then:
y-yo = m (x-x0)
m = (y2-y1) / (x2-x1)
m = (4 - (- 1)) / (4 - (- 3))
m = 5/7
We choose an ordered pair:
(xo, yo) = (4, 4)
Substituting:
y-4 = (5/7) (x-4)
y = (5/7) x-20/7 + 4
7y = 5x - 20 + 28
7y = 5x + 8
y = (5/7) x + 8/7
The equation of the perpendicular line is:
-7x - 5y = -48

You want the values of x that satisfy the inequality -x +6 ≥ 10.
SolutionThe inequality can be solved by adding x-10 to both sides
(-x +6) +(x -10) ≥ (10) + (x -10)

x = 0, y = 0 - 4 = -4

Find f(h(-1)).
-9

11
-11
Answers
Answer:
f(h(-1)) = - 11 or D
Step-by-step explanation:
h(-1) = -2(-1)^2 - 3(-1) + 1
h(-1) = -2(1) + 3 + 1
h(-1) = 2
f(2) = (2t + 7)/(t - 3)
f(2) = (2*2 + 7) / (2 - 3)
f(2) = 11/-1
f(2) = - 11
Be very careful how you handle this. The way I have done it will work, but it does not work all the time.
The sure way to handle this is to put(h(n)) every place you can on the right side of f(t)
f(h(n)) = (2(h(n) + 7)) / (h(n) - 3)

Answers
Answer:
1 and 7/8 is the change.
Step-by-step explanation:
First, make the bottom to fractions have the same denominator so we can figure out the length of the other route. 2 and 3/8 will become 2 and 9/24.
Then 3 and 5/6 will become 3 and 20/24. Add them both to get 6 and 5/24. since we cant simplify it stays the same. so now we convert the other number for the new road so it can match the old route. 4 and 1/3 become 4 and 8/24. Now we finish off by subtracting our two numbers to get 1 and 21/24. Since we can simplify the number now becomes 1 and 7/8.
Hope this helped.

Jayden's monthly bank statement showed the following deposits and withdrawals:
-−$73.59, -−$7.81, $86.90, $6.74, -−$115.75
If Jayden's balance in the account was $85.62 at the beginning of the month, what was the account balance at the end of the month?
Answers
Answer:
-17.89
Step-by-step explanation:
I think this is the answer
Start with the beginning balance then add or subtract the given amounts:
85.62 -73.59 = 12.03
12.03-7.81 = 4.22
4.22 + 86.90 = 91.12
91.12+ 6.74 = 97.86
97.86-115.75 = -17.89
Answer: -$17.89
The world population is projected to be 8.2 billion in 2045. At that time, there are expected to be approximately 3 billion more people in Asia than in Africa. The population for the rest of the world will be approximately 0.2 billion more than half the population of Asia. Find the projected populations of Asia, Africa, and the rest of the world in 2045.
The projected population of Asia will be approximately billion
Answers
Answer:
Since the total population will be 9.4B people
W + A+ A =9.4B
W = 0.6B + A/4
A+ 2.9B = As
A - 2.9B + As + 0.6 + A/4 = 9.4B
(9/4)*A= 11.7B
A = (4/9)*11.7B=5.2B
W = 0.6B + (5.2B/4) = 1.9B
A = 5.2B - 2.9B = 2.3B
