Write an equation for the line parallel to 5x=7+y and through the point (-1,-3). Graph both lines.

For lines to be parallel they must have the same slope. Since our reference line is y=5x-7 the parallel line must have the same slope, in this case 5.

So our parallel line thus far has the form:

y=5x+b, using point (-1,-3) we can find the y-intercept or "b"

-3=5(-1)+b

-3=-5+b

b=2 so the parallel line is:

y=5x+2

HELPP. Write the following as an algebraic expression. The sum of a and a quarter of b.

Fynjy0 [20]

Answer: $a + \frac{1}{4}b$

This is the same as $a + \frac{b}{4}$

All we're doing is adding 'a' and $\frac{1}{4}b$ since the term "sum" is the result of adding two or more numbers.

One quarter of a number is the same as dividing by 4.

Example: one quarter of 28 = $\frac{1}{4}*28 = \frac{28}{4} = 7$

What is the value of x

Solve this2^x=3^(x+1) what are the exact and approximate solutions

GrogVix [38]

Take the logarithm of both sides

x = $log_{2}$ (3)x + $log_{2}$ (3)

Move expression

x- $log_{2}$ (3)x = $log_{2}$ (3)

Factor out x

x(1- $log_{2}$ (3)) = $log_{2}$ (3)

Divide

x = ( $log_{2}$ (3)) / (1- $log_{2}$ (3))
