I'm also just learning bout this ,
i'm sorry

but i should give so clue

in a projective plane, two triangles<span> are said to </span>be perspective<span> from a </span>point if<span> the three lines</span> joining corresponding<span> vertices of the </span>triangles<span> meet at a common </span>point<span> called the center. ... Desargues' Theorem: </span>If two triangles<span> are </span>perspective<span> from a </span>point then<span> they are </span>perspective<span> from a line.</span>

Simplify your answer and write it as a proper fraction,improper fraction,or interger

ioda

Answer:

2

Step-by-step explanation:

Take any 2 points on the graph,

(80, 90) & (40, 10)

Use the slope formula:

$\frac{y2-y1}{x2-x1}$

= (10-90)/(40-80)

= (-80)/(-40)

= 2

Hence, the slope is 2.

Isoke is solving the quadratic equation by completing the square.10x2 + 40x – 13 = 0 10x2 + 40x = 13 A(x2 + 4x) = 13What is the

Elina [12.6K]

we have

$10x^{2} + 40x - 13 = 0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$10x^{2} + 40x =13$

Factor the leading coefficient

$10(x^{2} + 4x) =13$ ----------> the value of A is $10$

Complete the square. Remember to balance the equation by adding the same constants to each side

$10(x^{2} + 4x+4) =13+40$

$10(x^{2} + 4x+4) =53$

Rewrite as perfect squares

$10(x+2)^{2} =53$

$10(x+2)^{2} =53 \\ (x+2)^{2} =\frac{53}{10} \\ \\ x+2=(+/-)\sqrt{\frac{53}{10}} \\ \\ x1=-2+\sqrt{\frac{53}{10}}\\ \\ x2=-2-\sqrt{\frac{53}{10}}$

therefore

the answer is

the value of A is $10$
