3x + 2y = 5 5x + 2y = 7 Based on the given system of equations, which of the following is not true? 2x = 2 8x = 12 4y = 4
weqwewe [10]
<h3>Answer:</h3>

8x = 12

<h3>Explanation:</h3>

Subtracting the first equation from the second, you get ...

... (5x +2y) -(3x +2y) = (7) -(5)

... 2x = 2 . . . . . the first answer choice is true

___

Multiplying this expression for x by 4, we get

... 8x = 8 . . . . . the second answer choice (8x=12) is false

___

Adding thee first equation to the second, you get ...

... (3x +2y) +(5x +2y) = (5) +(7)

... 8x +4y = 12

... 8 + 4y = 12 . . . . . . use the value of 8x just computed

... 4y = 4 . . . . . . . . . . subtract 8; the third answer choice is true

_____

<em>Alternate approaches</em>

In short, if you solve the system by any of the methods available, you find x=1 and y=1, so the second answer choice is clearly the correct one:

... 8x ≠ 12

By Cramer's method:

... x = (2·7-2·5)/(2·5-2·3) = 4/4 = 1

... y = (5·5-7·3)/4 = 4/4 = 1

By graphing, see attached.

By substitution (for 2y):

... 5x +(5-3x) =7 . . . . . using 2y=5-3x

... 2x = 2 . . . . . . subtract 5

... x = 1 . . . . . . . .divide by 2

... 5 -3·1 = 2y = 2 . . . . substitute x into the expression for 2y

... y = 1 . . . . . . . divide by 2

By matrix methods, see the second attachment. (x, y) = (1, 1), found in the rightmost column of the result.

What is the answer to this... 2/3+w=1 1/2
Natali5045456 [20]
Hi there,

2/3 + w = 11/2
w = 11/2 - 2/3

Hence, W = 29/6

Hope this helps :)

Area of the shaded segment=
garik1379 [7]

The area of the entire sector is (\pi)(6^{2}) \left(\frac{60}{360} \right)=6\pi

The area of the triangle OAB is \frac{\sqrt{3}}{4}(6^{2})=9\sqrt{3}.

So, the area of the segment is \boxed{6\pi-9\sqrt{3}}

I need help with math if you don't know the answer get out of the question and don't answer it and give the wrong answer or some
Butoxors [25]

Answer:for the first one: 154.5852

Step-by-step explanation:

720 devided by 4 is 180

180 devided by 7 is 25.7142

so 25.7142x6=154.2852

so depending on what year your in, write the remainder or dont :)

~

120 devided by 5 is 24

thats all I know I tried w question 2 but it hurts mah brain, especially cuz I have *mental disorder* so its hard to focus aha- sorry
