Need some help with this one.

Verizon [17]

Answer:

x² + 4x + 3

Step-by-step explanation:

to find f(g(x)), substitute x = g(x) into f(x)

f(g(x)) = f(x + 2) = (x + 2)² - 1 = x² + 4x + 4 - 1 = x² + 4x + 3

Give the property that justifies each step.

hjlf

Answer:

Please check the explanation below.

Step-by-step explanation:

Some of the properties are defined as:

Distributive property

a(b+c) = ab+ac

For example,

suppose a=1, b=2, c=3

1(2+3) = 1(2) + 1(3)

5 = 2+3 = 5

Subtraction property of Equality

if (a=b), then a-c = b-c

For example,

suppose a=1, b=1, c=3

if a = b ⇒ 1 = 1

then a-c = b-c ⇒ 1-3 = 1 - 3 ⇒ -2 = -2

Addition property of Equality

if (a=b), then a+c = b+c

For example,

suppose a=1, b=1, c=3

if a = b ⇒ 1 = 1

then a+c = b+c ⇒ 1+3 = 1+3 ⇒ 4 = 4

Multiplicative property of Equality

if (a=b), then a×c = b×c

For example,

suppose a=1, b=1, c=3

if a = b ⇒ 1 = 1

then a×c = b×c ⇒ 1×3 = 1 × 3 ⇒ 3 = 3

Division property of Equality

if (a=b), then a÷c = b÷c

For example,

suppose a=1, b=1, c=3

if a = b ⇒ 1 = 1

then a÷c = b÷c ⇒ 1÷3 = 1 ÷ 3 ⇒ 1/3 = 1/3

Let's solve the given equation using the above properties.

5(x+10) = 20 Given

5x+50 = 20 1) Distriburive property ∵ a(b+c) = ab+ac

5x = -30 2) Subtraction property of Equality ∵ if (a=b), then a-c = b-c

x = -6 3) Division property of Equality ∵ if (a=b), then a÷c = b÷c

Answer:

$\large\boxed{\sqrt{10}-4\sqrt{10}=-3\sqrt{10}}$

Step-by-step explanation:

$\sqrt{10}-4\sqrt{10}=1\sqrt{10}-4\sqrt{10}=(1-4)\sqrt{10}=-3\sqrt{10}$

∆ABC is translated 2 units down and 1 unit to the left. Then it is rotated 90° clockwise about the origin to form ∆A′B′C′. The c

Ivenika [448]

Answer:

A'(-2, 1), B'(1, 0), C'(-1, 0)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.

If a point X(x, y) is translated a units right and b units down, the new location is X'(x + a, y + b) whereas if a point X(x, y) is translated a units left and b units up, the new location is X'(x - a, y - b).

If a point X(x, y) is rotated 90° clockwise about the origin, the new location is X'(y, -x)

From the image attached, ∆ABC is at A(0, 0), B(1,3) C(1, 1)

If ∆ABC is translated 2 units down and 1 unit to the left (x - 1, y - 2), the vertices would be A*(-1, -2), B*(0, 1), C*(0, -1)

If it is then rotated 90° clockwise about the origin, the new location is A'(-2, 1), B'(1, 0), C'(-1, 0)
