Lilli jogs 1/2 mile in 1/10 hour. What is Her rate per hour?

Her rate is five miles an hour. it is 1/2 a mile in 1/10 of an hour. you need to find 10/10 of an hour, so you multiply by 10. 1/2 x 10/1. 1 x 10 is 10. 2 x 1 is 2. so the answer would be 10/2, but it can be simplified. 10 and 2 have 2 in common. 10 divided by 2 is 5 and 2 divided by 2 is one. therefore the answer is 5/1, or just five. so 5 miles per hour. (or you can just do half of ten is five ;) )

The question is: "Without actually graphing, describe how the graph of y = ( -2^(x+17) ) - 4.3 is related to the graph of y = 2^

Leokris [45]

Answer:

The function has been flipped due to the negative in front.

The function has been shifted 17 units to the left.

The function has been shifted 4.3 units down.

Step-by-step explanation:

When functions are transformed there are a few simple rules:

Adding/subtracting inside the parenthesis to the input shifts the function left(+) and right(-).
Adding/subtracting outside the parenthesis to the output shifts the function up(+) and down(-).
Multiplying the function by a number less than 1 compresses it towards the x-axis.
Multiplying the function by a number greater than 1 stretches it away from the x-axis.
Multiplying by a negative flips the graph.

The graph of $(-2^{x+17}) -4.3$ compares to $2^x$ in the following ways:

The function has been flipped due to the negative in front.

The function has been shifted 17 units to the left.

The function has been shifted 4.3 units down.

Which graph or equation represents a Nonpoportional relationship A B C or D

VARVARA [1.3K]

Answer:

Step-by-step explanation:

A graph that represents a proportional relationship usually has the line cutting through the line of origin (0, 0).

The graph in option A does not have the line passing through the point of origin (0, 0), therefore, it does not represent a proportional relationship.

For an equation that represents a proportional relationship, it is written in the form of y = kx

Where, k is the constant of proportionality.

Therefore, the two equations given represents a proportional relationship.

4 = 1 - n + 4? Geometry btw

eimsori [14]

Answer:

N = -7

Step-by-step explanation:

4 = 1 - n -4

Subtract the numbers first

1 - 4 = -3

Then rearrange the terms

4 = -3 - n

-----> 4 = n - -3

The you add 3 to both sides of the equations

4 + 3 = -n - 3 + 3
