Answer:

The correct option is;

D. 1. Same-Side Interior Angles Theorem

2. Transitive Property

Step-by-step explanation:

The two column proof is given as follows;

Statement    {}                                            Justification

line AB║line EF   {}                                       Given

m∠KLF = 116°    {}                                          Given

1. m∠KLF + m∠BKL = 180    {}                      <u>1. Same side supplementary angles</u>

2. m∠BKL + m∠AKL = 180°    {}                     Linear pair postulate

3. m∠KLF + m∠BKL = m∠BKL + m∠AKL    {}<u>2. Transitive property</u>

4. m∠KLF = m∠AKL   {}                                  Subtraction property

A basketball is launched from a sling shot. Its height, h(x), can be represented by a quadratic function in terms of time x, in
BaLLatris [955]

Answer:

309 feet

Step-by-step explanation:

given that the height can be represented by a quadratic equation, we can say that the general form of the equation will look something like this:

h(x) = Ax² + Bx + C

we know that at the starting point of the launch that time = 0 (i.e x = 0) and hence h (x) = 0, if we substitute this into our equation, we can find the value for C

h(0) = A(0)² + B(0) + C = 0

C = 0

Hence the equation becomes

h(x) = Ax² + Bx

Given when x = 1, h(1) = 121,

121 = A(1)² + B(1)

A + B = 121 ------> eq 1

Given when x = 2, h(2) = 224,

224 = A(2)² + B(2)

4A + 2B = 224 (divide both sides by 2)

2A + B = 112------> eq 2

Solving the system of equations which comprise eq 1 and eq 2 using your favorite method, we end up with A = -9 and B = 130

our equation becomes:

h(x) = -9x² + 130x

when x = 3

h(3) = -9(3)² + 130(3) = 309 feet

Find the solution for this system of equations.<br><br>2x − 3y = 2<br> x = 6y − 5
IRINA_888 [86]

Answer:

y = 4/3

x = 2

Step-by-step explanation:

2x − 3y = 2

x = 6y − 5

x - 6y = -5

2x − 3y = 2 | ×1 |

x - 6y = -5 | ×2 |

2x − 3y = 2

2x - 12y = -10

____________--

9y = 12

y = 12/9

y = 4/3

2x − 3y = 2

2x - 3(4/3) = 2

2x - 4 = 2

2x = 2 + 4

2x = 6

x = 6/3

x = 2
