I hope this helps you
log(x-1)4^2=4
2.log (x-1)4=4
log (x-1)4=2
log (x-2)2^2=2
2log (x-1)2=2
log (x-1)2=1
[logab=y b=a^y]
b=2 a=x-1 y=1
2=(x-1)^1
x-1=2
x=3
Y = kx
4.8 = 4k
k = 4.8/4 = 1.2
Therefore, required equation = y = 1.2x
Remmeber, you can do anything to an equation as long as you do it to both sides
for inequalities, if you multiply or divide both sides by a negive, flip the direction of the inequality sign
pemdas always applies
but also the commutative property and assiociative property
so
2(5y+13)-6<20
add 6 both sides
2(5y+13)<26
divide both sides by 2 (easier that distributing)
5y+13<13
minus 13 both sides
5y<0
y<0 is the solution
To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.
