Answer:
x = 5
Step-by-step explanation:
x + 5 = 
{Midpoint theorem}
2(x+ 5) = x² - x
2x + 10 = x² - x
x² - x - 2x - 10 = 0
x² - 3x - 10 = 0
x² - 5x + 2x - (5*2) = 0
x(x - 5) + 2(x - 5) = 0
(x -5)(x + 2) = 0
{x + 2 is ignored because measurement could not be in negative value}
x - 5 = 0
x = 5
"Understand the problem" might rightly consist of
• Perform this step first
• Identify what you are being asked to solve or find.
• Identify the important words or numbers in the problem
• Identify any instructions that you are supposed to follow
_____
One of my professors always insisted we start the solution of any problem by writing down what was Given, and what we had to Find, using those headers for the sections of the paper we turned in. Only after those were listed were we allowed to write the Solution. Solution papers that didn't have that format were tossed in the trash, and no credit was given. Harsh, but effective.
<span>The pair of integers that I chose are:
(a) sum is –3
5 + (-8) = -3
(b) difference is –5
2 - 7 = -5
(c) difference is 2
14 -12 = 2
(d) sum is 0
2 - 2 = 0</span>
Answer:
2+0.15x=3.20
Step-by-step explanation:
So you have the original or starting point $2 which b in y=Mx+b then it’s 0.15 per day but you don’t know how many days so you use x and she owed a total of 3.20
Three of the points that are on the graph are
- (-1.38,2.05)= y=11+5x/2
- (0,5.5)= y-intercept, (0,11/2)
- (-2.2,0)= x-intercept, (-11/5,0)
