Answer: c. f - 3 + 6d
Explanation: 5d - d + 4 + 2d - 5f - 6f - 7
- 5f - 6f = f
4 - 7 = -3
5d - d = 4d, 4d + 2d = 6d
Answer:
- <u>No, he can get an output of 0 with the second machine (function B) but he cannot get an output of 0 with the first machine (function A).</u>
Explanation
The way each machine works is given by the expression (function) inside it.
<u>1) </u><em><u>Function A</u></em>
To get an output of 0 with the function y = x² + 3, you must solve the equation x² + 3 = 0.
Since x² is zero or positive for any real number, x² + 3 will never be less than 3 (the minimum value of x² + 3 is 3). So, it is not possible to get an output of 0 with the first machine.
<u>2) </u><em><u>Function B</u></em>
Solve 
So, he can get an output of 0 by using x = 4.
Answer:
the third option is the correct
Answer:
Step-by-step explanation:
G is the centeroid of the triangle. G splits AE in the ratio 2 : 1
AG : GE = 2 : 1
AG = 2x and GE = x
2x = 20
x = 20/2
x = 10
GE = 10 ; AG = 20
AE = 20+10 = 30
CG : GD = 2:1
CG = 2x and GD = x
2x = 10
x = 10/2
x = 5
GD = 5
BF = 30
BG : GF = 2 : 1
BG = 2x ; GF = x
BF = 30
BG + GF = 30
2x + x = 30
3x = 30
x = 30/3
x = 10
GF = 10
The width was 20 cm and was brought down to 5 cm, you can see that the pictures width was shrunk down 4 times because 20 divide by 4 is 5 so to find the length you would divide 30 by 4 and get 7.5 cm as your answer.
