Which ordered pair is a solution of y = x + 4

(0,0)
(5,54)
(7,28)
(9,13)

!

(9,13)

Step-by-step explanation:

A solution to an equation is a point (x,y) which makes the equation true.

y = x + 4

Substitute each point to determine if a solution.

(0,0) > 0 = 4 No

(5, 54) > 54 = 9 No

(7,28) > 28 = 11 No

(9,13) > 13 = 13 YES

step-by-step explanation:

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
