Answer:

To solve an equation in the form of x^2, you square root both sides of the equation, since x^2 equal x^x, the square root of x^2 is x

To solve an equation in the from of √=x, you square both sides of the equation, the square root of x's square is x, √x^2 = x.

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.

I can only help you with the second one. It is a positive correlation because it is going upwards. Good luck with the first one!

*50 POINTS -- FRESHMEN ~ ALGEBRA I *

aniked [119]

Step-by-step explanation:

so we know X= Numbers of Large boxes and Y= Numbers of Small boxes

And we know the large boxes weigh 75 pounds and the small boxes weigh 40 pounds

So I would have to say the the same except you have to flip the inequality sign like this:

75x + 40y

$\geqslant \\$

200

And if that doesnt somehow work and the question is wording it wrong then

My guess for why its wrong us because its not in slope intercept form Although you still can solve for either varible ( x or y) using standard form also.

So to get from standard form to Slope intercept form (y=mx+b) these are the steps:

Ax+by=C

75x + 40y ≤ 200

Turn it into a linear equation.

75x+ 40y =200

In order to go from one form to another, all you have to do is change the order of the given numbers. First you want to move the Ax to the opposite side of the equation, by either adding or subtracting it. At this point your equation will be set up By = -Ax + C. Then you want to divide the B from the By and the rest of the equation. Therefore you will have y = - Ax/B + C/B. This is the same thing as the slope-intercept form, just a few of the letters are different.

40y=-75x+200 first subtract 75x

y=−1.875×+5 then dived every varible (everything) by 40. and you have your Linear eqaution.

And your second question would be A. >The number of boxes must be a whole number. 

Because you cannot split boxes in half or in any quarter in a real life scenario.
