SHOW ALL WORK: Graph each lineby plotting its intercepts or by using the y intercept and slope. {2x-y=4 {3y-3x=6
pickupchik [31]

Answer:

x-y=-2

Step-by-step explanation:

Divide both sides if the equations by 3.

(3y-3x)÷3=6÷3

y-3x÷3=2

calculate the quotient

y-x=2

multiply both sides of the equation bub -1

-1x(-x)-1y=-1x2

any expression multiplied by -1

x-1y=-1x2

any expression multiplied by 1 remains the same.

x--y=-1x2

x-y=-2

Solve for x.<br><br> log x + log 3 = log 18<br><br> Enter your answer in the box.
Makovka662 [10]

log(x) + log(3) = log(18)

log(x) + 0.477121 = 1.255273

Add -0.477121 to both sides.

log(x) + 0.477121 + −0.477121 = 1.255273 + −0.477121

log(x)+0 = 0.778152

Divide both sides by 1.

log(x)+0/1 = 0.778152/1

log(x)=0.778152

Solve Logarithm

log(x) = 0.778152

10log(x) = 100.778152

x = 100.778152

x = 6.00001
