Solve the system of equations below by graphing. x^2-2x+y-3=0 x2+y=0 What is the solution rounded to the nearest hundredth? (–2.

Olin [163]

Answer:

$(-1.5,-2.25)$

Step-by-step explanation:

The first function is $x^2-2x+y-3=0$ .

We make y the subject of this function to obtain,

$y=3+2x-x^2$ .

This is graph will open downwards because $a=-1\:$ .

At y-intercept of this graph, $x=0$ .

$\Rightarrow y=3+2(0)-(0)^2$

$\Rightarrow y=3$

The y-intercept is $(0,3)$ .

At x-intercept $y=0$ .

$0=3+2x-x^2$

$0=(x+1)(x-3)$

$\Rightarrow x=-1,x=3$ .

The x-intercepts are,

$(-1,0),(3,0)$

Also the vertex form of the function is,

$y=-(x-1)^2+4$ .

Therefore the vertex of the parabola is $(1,4)$ .

We plot all the points obtained and draw a smooth curve to obtain the curve as show in the diagram.

The second function is

$x^2+y=0$

$\Rightarrow y=-x^2$

This is the graph of the basic quadratic function $y=x^2$ that has been turned upside down.

This graph also has the vertex,y-intercept and x-intercept all at $(0,0)$ .

We now graph this too on the same graph sheet as the first one to obtain the blue graph as shown in the diagram.

These two graphs intersect at the point, $(-1.5,-2.25)$ .

Therefore the correct answer is B

If you eat a diet with 2,000 kilocalories and 45 percent of those calories come from protein, about how many grams of protein di

jekas [21]

The amount of Protein intake is 900 kilocalorie.

We have - 2000 Kilocalories of diet and 45 Percent of calories come from Proteins.

Wе have to find out the amount of protein intake.

<h3>If ' x ' students out of total ' n ' students in a class are infected by virus. Then, what percentage of students are infected.</h3>

Percentage of students affected are - $\frac{x}{n} \times 100$

In the question given -

Let the amount of Protein intake be y.

Then -

45 = y % of 2000

45 = $\frac{y}{2000} \times100$

y = $\frac{45\times2000}{100}$

y = 900 Kilocalorie

Hence, the amount of Protein intake is 900 kilocalorie.
