4.1+(-4)= -3
6. 2
8. -18
10. 19
12. 42
14. 0
Answer:
Step-by-step explanation:
2) let the two numbers be x and y
x-y =15
(taking x to be big)
x = 3 (y)+1
i.e. x-3y =1
Subtracting we get
2y =14 or y =7
x =15+7 =22
Larger number is 22 and smaller number is 7
-----------------------------------
Alysha is 2 years younger than Bryce/
Let Alysha be x years old then Bryce would be x+2
Sum of their ages
=x+x+2 =28
2x+2 =28
2x=26
x=13
Hence Alysha is 13 years old and Bryce 14 years old.
number is 21
let the number be n then dividing by 3 gives and adding - 3 gives
- 3 = 4 ( add 3 to both sides )
= 7 ( multiply both sides by 3 )
n = 3 × 7 = 21
Given the function f(x);
Evaluating the function f(x+h);
So;
Evaluating the second function;
simplifying further;
Therefore, we have;
