Answer:

9.85

Step-by-step explanation:

you can use the Pythagoras theorem

a^2+b^2=c^2

with c the hypotenuse

9^2+4^2=c^2\\\\81+16=c^2\\\\97=c^2\\\\c=\sqrt{97}

which is aprox

Answer:

Remeber that

A^{2}+ B^{2} =C^{2}

so

4^{2}+9^{2}=C^{2}

16+81 = C^{2}

97 = C^{2}

Take the square root of both sides

\sqrt{97} = \sqrt{C^{2} }

9.85 = C

The graph of f(x) = 2x + 3 shifts 10 units to the right when it is replaced with the graph of f(x) = 2x − k. What is the value o
Nezavi [6.7K]

Answer:

k=17

Step-by-step explanation:

Given F(x)=2x+3  shifts 10 units when it is replaced with the graph f(x)=2x-k.

The method to solve this kind of questions is find where the graph meets the x axis then add ten units to it .The obtained x coordinate is the point where the second graph meets the x axis.

Now first find where the F(x)=2x+3 meets the x axis by substituting F(x)=0.

2x+3=0

x=-\frac{3}{2}

Now add 10 to this x coordinate , we get x1=10-3/2=17/2

this is x coordinate where the second line meets the x-axis.

The second line is F(x)=2x-k.

now f(x)=0 and x=17/2

On substitution we get 0=2*17/2-k

k=17
