The correct answer is B) AC = BC
We know this because the two triangles are equal due to SAS

Answer:

$(a)\ x + 4 = \±\sqrt9$ ---- $x =\{-7,- 1\}$

$(b)\ x - 4 = \±\sqrt9$ ---- $x = \{1,7\}$

$(c)\ x + 3 = \±\sqrt{16}$ ----- $x = \{-7,1\}$

$(d)\ x - 3 = \±\sqrt{16}$ ---- $x = \{-1,7\}$

Step-by-step explanation:

Given

The attached equations

Required

Match each with the solution

$(a)\ x + 4 = \±\sqrt9$

Take the square root of 9

$x + 4 = \±3$

Solve for x

$x =- 4 \±3$

Split

$x =\{- 4 -3,- 4 +3\}$

$x =\{-7,- 1\}$

$(b)\ x - 4 = \±\sqrt9$

Take the square root of 9

$x - 4 = \±3$

Solve for x

$x = 4 \±3$

Split

$x = \{4 -3,4+3\}$

$x = \{1,7\}$

$(c)\ x + 3 = \±\sqrt{16}$

Take the square root of 16

$x + 3 = \±4$

Solve for x

$x =- 3 \±4$

Split

$x = \{-3-4,-3+4\}$

$x = \{-7,1\}$

$(d)\ x - 3 = \±\sqrt{16}$

Take the square root of 16

$x - 3 = \±4$

Solve for x

$x =3 \±4$

Split

$x = \{3-4,3+4\}$

$x = \{-1,7\}$

On the graph shown, what is f(-1)? (5 points) The first segment joints the point negative three comma five exclusively and negat

ANSWER

$f( - 1) = 2$

EXPLANATION

The given function is a piecewise defined function.

$f( - 1)$
is the y-value that corresponds to
$x = - 1.$

To determine that y-value, we need to trace from
$x = - 1$
to where it meets the graph.

We then trace to the y-axis to determine the corresponding y-value as shown in the diagram.

From the graph, we can see that this x-value corresponds to a y-value of
$2$

This implies that, when
$x = - 1,y = 2$

Therefore
$f( - 1) = 2$
See graph.
