Which of the following shows the correct evaluation for the exponential expression 6 over 7 to the power of 2 ? a
6 over 7 plus 2 equals 2 and 6 over 7

b
6 over 7 times 2 equals 12 over 7 which equals 1 and 5 over 7

c
6 over 7 times 6 over 7 equals 36 over 49

d
6 over 7 divided by 2 equals 6 over 14

your welcome haha, this is the best place to find answers

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

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
