Which of the following ordered pairs should be tested to determine which side to shade when graphing the inequality y> 5x + 1?
A. Two points below the line y = 5x + 1
B. Two points above the line y = 5x + 1
C. A point on either side of the line y = 5x + 1
D. A point on the line y = 5x + 1

C.

If the line doesn't pass through the origin, the easiest point to pick is the origin (0,0).  Substitute into your inequality.

y > 5x + 1

0 > 5(0) + 1

0 > 1   which is a false statement.

So, you shade the side of the line on which (0,0) doesn't lie.

If the statement would have be true, you shade the side of the line on which (0,0) lies.

just sum

10 + 10 = 20

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
