Set up a proportion. If 12 3/5 feet can be traveled in one minute, then make that a fraction. 12 3/5 over one equals X over 30. Cross multiply 12 3/5×30 equals 1 X and solve.

H(y)=9/5 • 2y at y=-2
Deffense [45]

Answer:

H( - 2) = - 7  \frac{1}{5}

Step-by-step explanation:

We want to evaluate the equation

H(y) =  \frac{9}{5}  \times 2y

at y=-2

We just have to substitute to obtain;

H( - 2) =  \frac{9}{5}  \times 2 \times  - 2

We now multiply to get:

H( - 2) =  \frac{9}{5}   \times  - 4

This is the same as:

H( - 2) =  \frac{9}{5}  \times \frac{ - 4}{1}

We multiply the numerators separately and denominators separately to get:

H( - 2) =  \frac{9 \times  - 4}{5 \times 1}

H( - 2) =  \frac{ - 36}{5}

This implies that

H( - 2) = - 7  \frac{1}{5}

Given f(x) and g(x) = f(x + k), use the graph to determine the value of k.
dedylja [7]

g(x) is basically transformed f(x). First, let's focus on f(x) graph. Notice how the graph has slope of 1 and intersect y-axis at (0,0).

Which means that our equation for f(x) is:

\large{f(x) = x}

Now then we focus on g(x). g(x) is f(x+k). That means if f(x) = x then f(x+k) would mean substitute x = x+k in the equation.

\large{f(x + k) = x + k }\\  \large{g(x) = x + k}

Next, we want to find the value of k. In the slope-intercept form or y = mx+b where m = slope and b = y-intercept. Notice the g(x) graph and see that the graph intersects y-axis at (0,4). Therefore k = y-intercept = 4.

\large{g(x) = x + 4}

Answer

  • g(x) = x+4
  • Therefore the value of k is 4.
