Answer:

PAGE 1

A. Since PEMDAS 2*3 first

2*3 = 6

then 8/2

8/2 = 4

leaving

11 + 7 - 6 + 4

next 11 + 7

11 + 7 = 18

18 - 6 + 4

18 - 6 = 12

12 + 4 = 16

your answer is 16

B. No because John did not complete his problem correctly. The right answer is 16.

PAGE 2

A. Because of PEMDAS 4 * 12 first

4 * 12 = 48

then 48/3 = 16

your equation comes to

48 + 16 -15

then do

48 + 16 = 64

64 - 15 = 49

the answer is 49

B. If you don't do PEMDAS it can cost you the right answer.

See what answer you get when you don't do PEMDAS and just complete the equation left to right

48 + 4 = 52

52 * 12 = 624

624/3 = 208

208 - 15 = 193

the wrong non-PEMDAS used answer would then be 193

hope this helps:)

Find the slope and describe the line. (10,-1) & (7,-1)

Margaret [11]

Answer:

The slope is zero. Since both coordinates have the y-value of -1, they are on the same line on the graph and form a horizontal line with a slope of zero. (a straight horizontal line)

Step-by-step explanation:

use the formula

(y2-y1)/(x2-x1)

to calculate the slope using 2 points

so where (x1,y1) (x2,y2) can be subsituted

so putting it in the formula ...

(-1-(-1))/(7-10)=

I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
PLEASE SEE ATTACHED IMAGE.

For this case we have the following function:
f (x) = 7,400,000 (1,054) ^ x
Where,
x represents time in years.
Substituting f (x) = 15000000 we have:
15000000 = 7,400,000 (1,054) ^ x
Clearing x we have:
(1,054) ^ x = (15000000) / (7400000)
log1.054 ((1.054) ^ x) = log1.054 ((15000000) / (7400000))
x = log1.054 ((15000000) / (7400000))
x = 13.4 years
Rounding to the nearest year:
x = 14 years
Answer:
the population will reach 15,000,000 in 2014.
