Transform the equation to isolate x: ax = bx + 1. How is the value of x related to the difference of a and b? The equation ax =
Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

This is awfully hard to read. Use returns to separate paragraphs.

ax = bx + 1                Subtract bx from both sides.

ax - bx = 1                take out x as a common factor

x(a - b) = 1                Divide both sides by a - b

x = 1 / (a - b)

I think the second one is the one you want.

x is the same as the reciprocal of the difference between a and b.

Log(1+y) - log(1-y) = log x in 2 decimal places, express y in terms of x
GaryK [48]

Answer: y = \frac{x-1}{x+1}

Step-by-step explanation:

log(1+y) - log(1-y) = log x \\log\frac{1+y}{1-y} =log x\\x = \frac{1+y}{1-y}\\x(1-y)=1+y\\x-xy=1+y\\x-1 = xy+y\\y(x+1)=x-1\\y=\frac{x-1}{x+1}

Can someone help I am struggling with the question on the photo?
AleksandrR [38]

Answer:

in the last one 3+4+4×15=67

in the first if we see there are three shapes if we divide 45/3 so the value of each shape is 15

in the second there are two bananas and one shape as we know the value of shape so 23-15=8 as there are two bananas so the value of each banana is 4

in the third there are two clocks and one banana as we know the value of banana so 10-4=6 as there are two clocks so the value of each clock is 3

from above

shape=15 banana=4 and clock =3 pitting in the equation gives us the value of 67

Step-by-step explanation:

i hope this will help you :)
