Answer: -5
Step-by-step explanation:
im going to assume tomorrow means Two more.....
brilliant.
lets do opposite calculations to both sides. what is the opposite of 2? negative 2. so lets subtract 2 from both sides.
we get
ok so now we have 4 times x. what is the opposite of this? 4 DIVIDED BY x.
ok now lets do the same to the other side. what is negative 20 divided by 4?
Answer:
Step-by-step explanation:
we know that
The given equation y=5 is a horizontal line (is parallel to the x-axis)
The slope of the given line is equal to zero
A perpendicular line to the given line is a vertical line (parallel to the y-axis)
so
The equation of a vertical line is equal to the x-coordinate of the point that passes through it
The point that passes through it is (-4,-6)
therefore
The equation of the perpendicular line is
for the first one it is the second option because of one property of logarithms:
log(a)-log(b)=log
for the second one using the same property we can say that we third option is correct and not the second one but we use one more property of the logarithm
loga(b)^x=xloga(b) the power of the logarithm becomes a fator and is equal to
