Answer:

x = 21/2

y = -19/2

Step-by-step explanation:

5x - 17 = 4y + 7x

5x - 7x - 4y = 17

-2x - 4y = 17

6x + 8y = - 13

-2x - 4y = 17 | ×2 |

6x + 8y = - 13 | ×1 |

-4x - 8y = 34

6x + 8y = - 13

___________+

2x = 21

x = 21/2

-2x - 4y = 17

-2(21/2) - 4y = 17

-21 - 4y = 17

-4y = 17 + 21

-4y = 38

y = -38/4

y = -19/2

A measure of three angles of a triangle is shown below. What is the measurement of x? Record your answer in the gridable below.
Kaylis [27]

x + (x + 2) + 38 = 180

2x + 40 = 180

2x = 140

x = 70

In circle J with \text{m} \angle HLK= 30^{\circ}m∠HLK=30
olga2289 [7]

Answer:

The minor arc HK is 60 degrees

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The inscribed angle is half that of the arc it comprises.

so

m\angle HLK=\frac{1}{2}(arc\ HK)

we have

m\angle HLK=30^o

substitute the given value

30^o=\frac{1}{2}(arc\ HK)

arc\ HK=60^o

Remember that the measure of the minor arc must be less than 180 degrees

therefore

The minor arc HK is 60 degrees

Please help me!!!!!

Answer:

y = - \frac{2}{5} (x - 5)² + 7

Step-by-step explanation:

The equation of a quadratic in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

Here (h, k ) = (5, 7 ) , then

y = a(x - 5)² + 7

To find a substitute (10, - 3 ) into the equation

- 3 = a(10 - 5)² + 7 ( subtract 7 from both sides )

- 10 = 5²a = 25a ( divide both sides by 25 )

\frac{-10}{25} = a , that is

a = - \frac{2}{5}

y = - \frac{2}{5} (x - 5)² + 7 ← in vertex form
