Answer:
0 = (3-2x) x (x x 2 -5)
(3-2x) x ( x x 2 - 5) = 0
(3-2x) x (2x - 5) = 0
3 - 2x = 0
2x - 5 = 0
x = 3/2
x = 5/2
x1 = 3/2 or x2 = 5/2
Answer:
896
Step-by-step explanation:
14 of 20 teens eats breakfast every morning.
The percentage of those who eat breakfast every morning
= 14/20 x 100%
= 0.7 x 100%
= 70%
So, 70% of 20 teens eat breakfast every morning.
The reasonable prediction for the number of teens that eats breakfast every morning from 1280 teens will be 70% of 1280.
70/100 x 1280
0.7 x 1280
896
The prediction would be 896 out of 1280 teens eats breakfast every morning
Divide the pentagon into a triangle and rectangle.
Rectangle: 12in*6in=72in^2
Triangle: (12in*5in)/2=30in^2
72in^2+30in^2=102in^2

There is an easy way to find y intercept. I can tell you how and show you the answer
1 {Y Intercept = 3 } [ This is where the line crosses the line going from up to down in the middle. ]
{slope = 2/1 } To find the slope you find a place where the slanted line is perfectly on the graph.:
You then go up. { GO UP FIRST! that will be the number on top. Stop when you notice the slanted line to the right is exactly on the graph. So what i did is started at (-1, 1) Then went up twice. I saw that to the right of me was the slanted line which was exactly on the graph. So I went up twice [2] then went right once [1]
To find your equation you just put y= [ y intercept form ] and your numbers you found.
y=2/1x + 3
Make sure you have x after your slope so you know it is always going up, no matter what number you put inside.
IF YOU WANT ME TO DO THEM ALL COMMENT. I WILL DO THEM ALL WITHOUT EXPLANATION.
** NOTE ** If the line is decreasing from the left. “\”it is negative so the slope will me - you will do that for your next question
