It says Sandeep has twice as much as Sonia. Thus, let Sandeep's amount be 2x and Sonia's amount be x.

Now, together they have 150.

Thus, the equation;

x+2x=150

Now let's solve the equation;

3x=150

x=150/3

x=50

Thus, Sonia has 50

Write the quadratic function in vertex form. Y = x2 + 16x + 74
Sidana [21]

<u>Answer-</u>

The vertex form of the given quadratic function is,

\boxed {\boxed {y = (x+8)^2+10}}

<u>Solution-</u>

The equation for a parabola or quadratic function can be written in <em>vertex form</em>-

y=a(x-h)^2+k

The given quadratic function,

\Rightarrow y = x^2 + 16x + 74

\Rightarrow y = (x)^2 + (2\times x \times \frac{16}{2}) + 74

\Rightarrow y = (x)^2 + (2\times x \times 8) + 74

\Rightarrow y = (x)^2 + (2\times x \times 8) + (8)^2+74-8^2

\Rightarrow y = (x+8)^2+74-64

\Rightarrow y = (x+8)^2+10

This is the vertex form of the given quadratic function with vertex at (-8, 10)

What is 4x-2y=8 and y=2x+1 using substitution
Setler [38]

Answer:

No Solution

Step-by-step explanation:

4x-2y=8

y=2x+1

Make the first equation into where it says y=.

-2y=-4x+8

y=2x-4

Substitute either equation into the other as y=.

2x+1=2x-4   or    2x-4=2x+1

Switch terms around so they're with their like terms. Make sure it becomes the opposite when switching.

2x-2x=-1-4    or    2x-2x=4+1

0=-5                     0=5

Since x did not come back to equal an answer, this problem is not workable. There is no solution to it. If you were to do it a different way, there still would not be a solution to it.
