Which ordered pair is a solution of the system of a linear equation below? Y= 1/4x +2 y= x-1
Tanya [424]

Answer:  x = 4, y = 3

<u>Step-by-step explanation:</u>

y=\dfrac{1}{4}x+2    and      y=x-1

Using substitution method we get:

x-1=\dfrac{1}{4}x+2\\\\\text{subtract}\ \dfrac{1}{4}x\ \text{from both sides}\rightarrow \dfrac{3}{4}x-1=2\\\\\text{add 1 to both sides}\rightarrow \dfrac{3}{4}x=3\\\\\text{multiply both sides by 4}\rightarrow 3x=12\\\\\text{divide both sides by 3}\rightarrow x=4\\\\\text{Insert x = 4 into one of the original equations to solve for y:}\\y=x-1\\y =(4)-1\\y=3

Write the following equation in logarithmic form <br> a^(4b-6)=3c+d
Tomtit [17]

Hello from MrBillDoesMath!

Answer:  (4b-6) log(a) = log (3c + d)

Discussion:

Take the log of both sides of the equation:


log ( a ^(4b-6))  = log (3c + d)  


As the log functions causes exponents to become multiplexers, this equation is the same as


(4b-6) log(a) = log (3c + d)


Thank you,

MrB
