What is the slope of 4x+5y= -10
Aleonysh [2.5K]

Answer:

-\frac{4}{5}

Step-by-step explanation:

To find the slope, rearrange the equation to y=mx+b or y=mx+c.

4x+5y=-10

Subtract 4x from both sides:

5y=-10-4x

Divide 5 on both sides:

y=\frac{-10-4x}{5}

y=-\frac{4}{5} x-2

In the equation of y=mx+b/y=mx+c, m will be the slope.

Therefore, the slope is -\frac{4}{5}

Which expression is equivalent to log_5(x/4)^2?
viktelen [127]

For this case we must find an expression equivalent to:

log_ {5} (\frac {x} {4}) ^ 2

So:

We expanded log_ {5} ((\frac {x} {4}) ^ 2)by moving 2 out of the logarithm:

2log_ {5} (\frac {x} {4})

By definition of logarithm properties we have to:

The logarithm of a product is equal to the sum of the logarithms of each factor:

log (xy) = log (x) + log (y)

The logarithm of a division is equal to the difference of logarithms of the numerator and denominator.

log (\frac {x} {y}) = log (x) -log (y)

Then, rewriting the expression:

2 (log_ {5} (x) -log_ {5} (4))

We apply distributive property:

2log_ {5} (x) -2log_ {5} (4)

Answer:

An equivalent expression is:

2log_ {5} (x) -2log_ {5} (4)
