Answer:

BC = 24

Step-by-step explanation:

In the picture attached, the missing triangles are shown:

AB = 10

BD = 5

DE= 12

Then, AD = 10-5 = 5

As a consequence of the "Side Splitter" Theorem:

AD/DE = AB/BC

Replacing with data and solving for BC

5/12 = 10/BC

BC = 10*12/5 = 24

What is the value of y in the solution to the following system of equations?

lukranit [14]

Answer:

Option D is the correct answer.

Step-by-step explanation:

The equations are:

5x - 3y = -11 Eqn 1

2x - 6y = -14 Eqn 2

We have to find the value of y so we will eliminate x.

Multiplying Eqn 1 by 2

2(5x-3y=-11)

10x-6y=-22 Eqn 3

Multiplying Eqn 2 by 5

5(2x-6y=-14)

10x-30y=-70 Eqn 4

Subtracting Eqn 4 from Eqn 3

(10x-6y)-(10x-30y)= -22-(-70)

10x-6y-10x+30y = -22 + 70

24y = 48

$\frac{24y}{24}=\frac{48}{24}\\y=2$

Therefore,

Option D is the correct answer.

The graph of g(x) is f(x) translated to the left 8 units and up 2 units. What is the function rule for g(x) given f(x) = x²?

NNADVOKAT [17]

Translation of a function y = h(x) to the right/left is given by y = h(x + a) for translation to the left by 'a' units and y = h(x - a) for translation to the right by 'a' units

Translation of a function y = h(x) up/down the y-axis is given by y = h(x) + a for translation 'a' unit up and y = h(x) - a for translation 'a' unit down

So, translating f(x) = x² eight units right and two units up gives:

g(x) = (x-8)² + 2
