Quick for hw lots of points asap need to finish quick

answer:

15 years

Step-by-step explanation:

Find the greatest common multiple.

The GCM is 15

Multiply 15 by 45 and add that to 1,100.

15*45=675            1,100+675=1,775

Multiply 15 by 15 and subtract that from 2,000.

15*15=225             2,000-225=1,775

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
