Answer:

Option D is the correct answer.

Step-by-step explanation:

Refer the given figure showing the graph.

We can see the point of intersection is (2.5, -2).

Option D is the correct answer.

<u>Alternatively:</u>

2x + y = 3  ---------------------eqn 1

2x - 5y = 15  ---------------------eqn 2

eqn1 - eqn 2 gives

  2x + y - ( 2x - 5y) = 3 - 15

           6y = -12

             y = -2

Substituting in eqn 1

         2x - 2 = 3

            x = 2.5

Point of intersection is (2.5, -2).

Option D is the correct answer.

Repost 8th grade 50 POINTS+BRAINLIEST: How do you graph a quadratic equation in vertex form when the equation is a perfect squar
Naddika [18.5K]

Answer: Vertex : Maximum (2, 0)

Rules:

  • (x + d)² = x² + 2dx + d²    and   (x - d)² = x² - 2dx + d²
  • x² + 2dx = (x + d)² - d²   and  x² - 2dx = (x - d)² - d²

Solve:

x² - 4x + 4

x² - 2(2x) + 2²

(x - 2)²

Into vertex form: a(x - h)² + k

1(x - 2)² + 0

Identify:

vertex : (h, k) = (2, 0)

Find additional things, to graph the equation:

(i) x-intercept: (2, 0)

(ii) y-intercept: (0, 4)

Graph shown:

PLZZZZZZZ HELPPPP
dolphi86 [110]

Answer:

The correct option is 1.

Step-by-step explanation:

It is given than the area of the triangle ABC is 46cm².

Area of a triangle is

A=\frac{1}{2}\times base\times height

Base of the triangle is AB and height of the triangle is CD.

A=\frac{1}{2}\times AB\times CD

A=\frac{1}{2}\times AB\times 8

A=4\times AB

The area of the triangle is 46cm².

46=4\times AB

AB=\frac{46}{4}

AB=11.5

Therefore the length of side AB is 11.5 cm. Option 1 is correct.
