Answer:
Step-by-step explanation:
first we put them in y = mx + b form...then we compare the slopes and the y int's. In y = mx + b form, the slope is in the m position and the y int is in the b position.
2x + 2y = 8
2y = -2x + 8
y = -x + 4......slope here is -1 and y int is 4
3x + y = 8
y = -3x + 8.....slope here is -3 and y int is 8
This system has 1 solution <===
================================
learn this...it helps
* if there are different slopes and different y int, then there is 1 solution
* if there are the same slopes and different y int, then there is no solutions because u have parallel lines
* if there are same slopes and same y int, there is infinite solutions because u have the same line
Answer: 296.7
i did surface area but i dont think this is right
Step-by-step explanation:
2πr^2+2πrh
2(3.14)(1.5)^2+2(3.14)(1.5)(30)
2(3.14)(2.25)+2(3.14)(45)
2(7.065)+2(141.3)
14.13+282.6=296.73
rounded to the nearest tenth: 296.7

Answer:
<u>The correct answer is D. 4.55</u>
Step-by-step explanation:
1. Let's check the information given to resolve the question:
What is the approximate value of 2π-√3?
2. Replacing the equation with the values:
π = 3.1416
√3 = 1.7321
2π-√3
2 (3.1416) - 1.7321 = 6.2832 - 1.7321 = 4.5511
4.55 (Rounding to two decimal places)
<u>The correct answer of 2π - 3 is D.4.55</u>
