If you shift the linear parent function, f(x) = x, down 6 units, what is the equation of the new function?
Colt1911 [192]

Answer:

f(x)=x-6

Step-by-step explanation:

Given : Parent function : f(x)=x

To Find : If you shift the linear parent function, f(x) = x, down 6 units, what is the equation of the new function?

Solution:

Parent function : f(x)=x

Shift the given function down by 6 units.

Rule : The graph f(x) shifts down by b units

So, f(x)→f(x)-b

So, Shift the given function down by 6 units.

So, f(x)→f(x)-6

f(x)=x

So, x→x-6

So, the new function is f(x)=x-6

Hey I’m struggling with number 13 so please show your work. Thx
Dafna11 [192]

Answer:

\frac{5}{12}

Step-by-step explanation:

Because \frac{3}{5} is being multiplied by S, we can divide \frac{3}{5} from both sides of the equation. This will give us:

\frac{1}{4}÷\frac{3}{5}

But, that looks a bit hectic. Instead of dividing, you can multiply by the reciprocal (which is essentially how to divide fractions). So, instead of \frac{1}{4}÷\frac{3}{5}, you get:

\frac{1}{4}×\frac{5}{3}

When multiplying fractions, remember you can just multiply straight across-- numerator x numerator, then denominator x denominator.

By doing that, you get the fraction \frac{5}{12}

\frac{5}{12} cannot be simplified any more, so S=\frac{5}{12} is your answer :)

I hope this helps

Carla is saving money for a trip. She already has some money in her savings account and will add the same amount to her account
Bingel [31]

Answer:

280=8x + 130

Step-by-step explanation:

Im pretty sure this is correct it has been a while since I did this but y is the total amount so y is 280. M is the slope so it would be how often the amount changes so m is 8. x is unknown and what needs to be solved for. b is the y intercept which is just the initial amount of 130.
