What is and equation line that passes through the point (8,-5) and is parallel to the line 5x+4y=24

9514 1404 393

  5x +4y = 20

Step-by-step explanation:

Put the given x- and y-values into the left-side expression to see the constant needed on the right.

  5(8) +4(-5) = 40 -20 = 20

The desired equation is ...

  5x +4y = 20

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.

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
