Answer:

h=2

a=4

k= -21

Step-by-step explanation:

your h and k are vertex . h= x coordinate of vertex and k= y

so formula for vertex coordinates is x= -b/2a and y= (4ac-b²)/4a

your a b c are 4 -16 and -5 respectively according to the main equation

your a is concavity which is the same number as the 'a' of the equation

Which of the following methods would be the easiest to use to solve x2 + 5x – 6 = 0?
EastWind [94]
For me personally, the easiest way to do this is by isolating the x² term, and finding the square root of both sides. The hardest way (well actually, the longest way) would be to use the quadratic formula. It just complicates things unnecessarily.

The figures are similar. Find the missing length.
saw5 [17]

Step-by-step explanation:

<h2>Answer:-</h2><h3>Given ,</h3>

The figure is Similar.

Observation:-

Similar figures have similar sides. If we see carefully in smaller triangle, 3 has been added to each side and they are similar. We need to find y.

We have :-

5+3=8 as similar sides.

So, applying same algorithm,

y + 3 = 5

y = 5 - 3

\boxed{ \tt{y = 2 \ cm}}

is the answer.

Hope it helps :)

What is the value of the x variable in the solution to the following system of equations? (5 points) 2x − 3y = 3 5x − 4y = 4 Sel
Rama09 [41]

Answer:

D. There is no x value as there is no solution to this system

Step-by-step explanation:

2x − 3y = 3                                  5x − 4y = 4

5x - 4y = 4               -4y = -5x + 4                         y = 5/4x - 1

2x - 3(5/4x - 1) = 3

2x - 15/4x + 3 = 3

-7/4x = 0

x = 0
