Answer:

Car B is faster

Car B is ×1.125 times faster

Step-by-step explanation:

Car A:

went 60 km in 5/6 hour

then

went 60/5 = 12 km in 1/6 hour

then

went 12 ×6 = <u><em>72 km</em></u> in 6/6 = 1 hour

Car B:

went 54 km in 2/3 hour

then

went 54/2 = 27 km in 1/3 hour

then

went 27 × 3 = <u><em>81 km</em></u> in 3/3 = 1 hour

81÷72 = 1.125

If g(x)=f(x+1), then g(x) translates the function f(x) 1 unit _[blank]_.
MakcuM [25]

ANSWER

Left

EXPLANATION

The given function is

g(x)=f(x+1)

This means that the base function is:

f(x).

The translation f(x+k) will shift the graph to left by k units while f(x-k) will shift the graph to right by k units

Therefore if g(x)=f(x+1) translates the function f(x) 1 unit left.

Answer: left

Use the distributive property to match equivalent expressions.
NeTakaya

Answer:

<h3>By using the distributive property the matched equivalent expressions are</h3><h3>1) -7(-4+x) =28-7x </h3><h3>2) -7(4-x) =-28+7x </h3><h3>3) 7(4+x) =28+7x </h3><h3>4) 7(-4-x) =-28-7x </h3>

Step-by-step explanation:

Given that by using the distributive property to match the given equivalent expressions.

1) Given expression is -7(-4+x)

<h3>By Distributive property a(b+c)=ab+ac</h3>

-7(-4+x) =(-7)(-4)+(-7)(x)

=28-7x

<h3>∴ -7(-4+x) =28-7x </h3>

2) Given expression is -7(4-x)

<h3>By Distributive property a(b+c)=ab+ac</h3>

-7(4-x) =(-7)(4)+(-7)(-x)

=-28+7x

<h3>∴ -7(4-x) =-28+7x </h3>

3) Given expression is 7(4+x)

<h3>By Distributive property a(b+c)=ab+ac</h3>

7(4+x) =(7)(4)+(7)(x)

=28+7x

<h3>∴ 7(4+x) =28+7x </h3>

4) Given expression is 7(-4-x)

<h3>By Distributive property a(b+c)=ab+ac</h3>

7(-4-x) =(7)(-4)+(7)(-x)

=-28-7x

<h3>∴ 7(-4-x) =-28-7x </h3>

Hence the matched equivalent expressions are

1) -7(-4+x) =28-7x

2) -7(4-x) =-28+7x

3) 7(4+x) =28+7x

4) 7(-4-x) =-28-7x

The graph shown below expresses a radical function that can be written in the form f(x)=a(x+k)^1/n + c. What does the graph tell
Pie

Answer: n is a positive odd number.

Step-by-step explanation:

Ok, we know that the function is something like:

f(x)=a(x+k)^1/n + c

In the graph we can see two thigns:

All the values of the graph are positive values (even for the negative values of x), but in the left side we can see that the function decreases and is different than the right side.

So this is not an even function, then n must be an odd number (n odd allows us to have negative values for y = f(x) that happen when x + k is negative).

Also, we can see that the function increases, if n was a negative number, like: n = -N

we would have:

f(x) =  \frac{a}{(x+k)^{1/N}}  + c

So in this case x is in the denominator, so as x increases, we would see that the value of y decreases, but that does not happen, so we can conclude that the value of n must be positive.

Then n is a positive odd number.
