Answer: False

Step-by-step explanation: In this equation, the Multiplication Property of Equality wouldn't help us because it tells us we can always multiply the same quantity times both sides of an equation.

Since we want to be able to get x by itself, multiplying both sides

of the equation by the same quantity wouldn't help us.

Instead, we would use the Division Property of Equality.

In order to get from the statement 5x = -20 to the statement where x

is isolated, we must divide both sides of the statement, 5x = -20, by 5.

So we have x = -4.

So this statement uses the Division Property of Equality.

What is the asymptote of g(x)= 4 (1/3) - 2

Nataly [62]

Answer: X=2

Step-by-step explanation:

Assuming the function is

All logarithmic functions, despite their base, has a vertical asymptote at argument = 0.

That is not changed by the vertical stretching made by the 4 which multiplies the logarithm nor the vertical shift made by the +5.

In this case the argument is x - 2, then the vertical asymptote is:

x - 2 = 0

bob travels from inglewood to Anytown; a distance of 20km. he walks 800m and cycles the rest of the way. What percentage of the

Semmy [17]

We can convert 20km to 20,000m. Then, we can subtract 800m (walking distance) from 20,000m which would result in 19,200m. Then we can put 19,200m and 20,000m as a fraction (19200/20000). Before we can multiply it by 100 to make it in the percentage form, we can get rid of 2 zeroes for both number making it 192/200 and then further simplifying it to 24/25 by dividing both numbers by 8. Finally to get the percentage we can multiply 24 and 100 (2400) and then divide the result (2400) by 25. The final answer is 2400/25=96 meaning he cycled 96% of the journey and walked 4% of the journey (100-96=4).
