Answer:
- 2 and 12
Step-by-step explanation:
let the 2 integers be x and y , x > y , then
x - y = 14 → (1)
x + y = 10 → (2)
add the 2 equations term by term to eliminate y
2x = 24 ( divide both sides by 2 )
x = 12
Substitute x = 12 into (2)
12 + y = 10 ( subtract 12 from both sides )
y = - 2
As a check
x + y = 12 + (- 2) = 12 - 2 = 10
x - y = 12 - (- 2) = 12 + 2 = 14
xy = 12 × - 2 = - 24
Answer:
He is ten.
Step-by-step explanation:
10 yrs old. Go ahead 10 yrs to make 20. Which is four times as much as five years old. (Which is 5 years before 10)
Hope this helps! :)
Hello
sin ..... | 0° |30°|45°|60°|90°|
...........| 0...| 1..| 2..| 3..| 4..| write numbers
...........| 0...| 1..|√2.| √3 | 2..| take root square
...........| 0...|1/2|√2/2|√3/2|1| divide by 2
...........| 0...|1/2|√2/2|√3/2|1| .....
cos.....| 90°|60°|45°|30°| 0°|
sin (75°)
=sin(30°+45°)=sin 30°*cos 45° +cos 30°*sin 45°
.................... =1/2*√2/2 + √3/2*√2/2
.................... = √2(1+√3)/4
cos 75°
=cos(30°+45°)=cos 30°*cos 45°-sin 30°*cos 45°
=√3/2*√2/2-1/2*√2/2
=√6/4-√2/4=√2/4*(√3 -1 )
1) y= 2/5x -3
2) y= 2/3x + 1
3) y= 2x -1
4) y= 5/4x + 3
I think
