Jenna concludes that (4,9) is the solution to the system of these two equations. which of the following justifies her conclusion
nalin [4]

<u><em>Answer:</em></u>

a. The point (4,9) appears in both tables

<u><em>Explanation:</em></u>

<u>Note:</u> This question can be solved without the need of the tables

<u>A solution of a system of equations</u> is defined as a point (or set of points) that satisfy both equations

<u>This means that,</u> this point should belong to all the equations in the system

Now, a table is used to show a set of points that belong to a certain line

This means that, all vales in the table belong to the line they represent

<u>Since the point (4,9) appears in both tables</u>, therefore, it belongs to both lines and, therefore, is a solution to the system of equations consisting of these two lines

Hope this helps :)

jonny [76]

Answer:

180 ml oil

240 g onions

1.35 kg potatoes

1.8 l milk

Step-by-step explanation:

The recipe makes 6 portions and you need 18 portions. Since 6 is 3 times smaller than what you need, just times everything you've been given by 3.

<em>*you can choose to convert into the correct units of measurement before or after dividing. I converted after dividing. Either way works fine though.</em>

1) 60 x 3 = 180 ml

2) 80 x 3 = 240 g

3) 450 x 3 = 1350 g

<em>They want it in kilograms, so divide it by 1,000 to convert. this gives you 1.35 kg.</em>

4) 600 x 3 = 1800 ml

<em>They want it in l, so divide it by 1,000 to convert. this gives you 1.8 l.</em>

Hope this helped : )

The hypotenuse in a right triangle is 13 cm. Of the other two sides one is 7 cm longer than the other determine the lengths of t
slamgirl [31]

Assuming x represents the length of the first side.

Use pythagorean theorem to solve:

<span>a^2</span> + <span>b^2</span> = <span>c^2</span>

<span>x^2</span> + <span><span>(x+7)^</span>2</span> = <span>13^2</span>

<span>x^2</span> + <span><span>x^2</span>+14x+49</span> = 169

<span>2<span>x^2</span></span> + 14x - 120 = 0

Solve the quadratic equation using the quadratic formula.

At the end, you will get side lengths of #(-14 ± 34) / 4, or -12 and 5

SInce a negative triangle length is impossible, 5 is the value of x and 5 + 7 is the value of x + 7, which makes 12.

The formula for area of a right triangle is A = <span>b<span>h/2</span></span>

A = <span><span>b<span>(h)</span></span>2</span>

A= <span><span>12<span>(5)</span></span>2</span>

A = <span>30c<span>m^<span>2</span></span></span>
