Answer:

$f(1)=-4$

Step-by-step explanation:

For finding out $f(1)$ , we have to find the value of y coordinate of the point where its x coordinate is 1.

From the given graph, the point $(1,-4)$ lies on the graph and has x coordinate as 1.

Drawing a vertical line x=1, it meets the graph at $(1,-4)$

Therefore, $f(1)=-4$

Evaluate f(x) = 2|x – 5| for f(–5) and f(0).

Elanso [62]

Answer:

f(–5) = 20, f(0) = 10

Step-by-step explanation:

f(-5):

f(-5) = 2|-5 -5|

f(-5) = 2|-10|

f(-5) = 2(10)

f(-5) = 20

f(0):

f(0) = 2|0 - 5|

f(0) = 2|-5|

f(0) = 2(5)

f(0) = 10

On the exam, Rebecca successfully created 20 out of 25 vases.

juin [17]

$\text{Hello there! :]}$

$\large\boxed{125 \text { vases}}$

$\text{To solve, find the proportion of successes from the total:}\\\\20 / 25 = 4 / 5\\\\\text{Set up a proportion to find the # of vases necessary to complete 100 successfully:}\\\\\frac{20}{25} = \frac{100}{x} \\\\\text{Cross multiply to solve:}\\\\20 * x = 100 * 25\\\\20x = 2500\\\\\text{Divide both sides by 20:}\\\\x = 125 \text{ vases}$
