<u>Step 1: Define</u>
(6x² - 10x + 9) + (-5x² + 9x - 5)
<u>Step 2: Simplify</u>
- Combine like terms (x²): x² - 10x + 9 + 9x - 5
- Combine like terms (x): x² - x + 9 - 5
- Combine like terms (Z): x² - x + 4
Answer:
(x+0.2)+7.8 is the correct answer la
Answer:
13 inches
Step-by-step explanation:
legs are 5 inch and 12 inch
we have to find hypotenuse
use formula
a^2 + b^2 =c^2
here a and b are legs of a triangle and hypotenuse is c so,
5^2 + 12^2 =c^2
25 + 144 =c^2
169 =c^2
=c
13 =c
therefore hypotenuse is 13 inches.
Step-by-step explanation:
The exact question is as follows :
Given - The value of π up to 35 decimal places is given below:
3.14159265358979323846264338327950288
To find - Make a frequency distribution of the digits 0 to 9 after the decimal point.
Proof -
The Frequency Distribution Table for digits after decimal point in the value of Pi is :
Digits Frequency after decimal point
0 1
1 2
2 5
3 6
4 3
5 4
6 3
7 2
8 5
9 4
Total Digits = 35
Step-by-step explanation:
3)
2x + 3y = 12
Solve for y. Then you have y = mx + b, and m is the slope.
3y = -2x + 12
y = -2/3 x + 12
slope = -2/3
6x - 4y = 8
-4y = -6x + 8
y = -6/(-4) x + 8/(-4)
y = 3/2 x - 2
slope = 3/2
Since the slopes -2/3 and 3/2 are opposite reciprocals, the lines are perpendicular.
4)
3x - 4y = 12
-4y = -3x + 12
y = -3/(-4) x + 12/(-4)
y = 3/4 x - 3
slope = 3/4
4x + 3y = 15
3y = -4x + 15
y = -4/3 x + 5
slope = -4/3
Since the slopes 3/4 and -4/3 are opposite reciprocals, the lines are perpendicular.
