First number is f
Second number is s
f-s=.7
f+s=1
Using elimination, you could solve this.
-1(f-s=.7); eliminate the first number.
-f+s= -.7
f+s=1
2s=.3
s=.15
Now find the second number by plugging it in:
.15+s=1
1-.15=.85
The numbers are .15 and .85.
The answer to your questions is 3.12
Answer:
4m
Step-by-step explanation:
- v=4/3 pi r^3
- substitute 267.95=4/3×3.14×r^3
- 267.95= 12.56r^3/3
- multiply by the reciprocal on both sides 64=r^3
- find the cuberoot on both sides to remove the cube hence 4=r
Answer:
f(x)=-4x+/4
let y=f(x)
y=-4x+4
interchange the role of x & y
x=-4y+4
x-4=-4y
(x-4)/-4=y
y=-(x-4)/4
f-¹(x)=-(x-4)/4
yeah you are right
3.2 is the answer.
