What do the slope and y-intercept mean? Group of answer choices The slope of 60 tells how much the sitting height increases for each 1 year increase in age. The y-intercept is 50 cm and gives the sitting height when the age is 0 years. The slope of 60 tells how much the sitting height increases for each 1 year increase in age. The y-intercept is 0 cm and gives the sitting height when the age is 0 years. The slope of 2.5 tells how much the sitting height increases for each 1 year increase in age. The y-intercept is 0 cm and gives the sitting height when the age is 0 years. The slope of 2.5 tells how much the sitting height increases for each 1 year

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

step-by-step explanation:

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
