Answer:
55/100
Step-by-step explanation:
Multiply 20 by 5 to get 100 so you multiply 11 by 5 to get 55
Answer:
No solution, the lines are parallel.
Step-by-step explanation:
Any line can be represented by the equation
y = mx + b
where m is the slope and b is the y intercept.
-3x + 4y = 12
4y = 3x + 12
y = 3/4 x + 3
AND
1/4 x - 1/3 y = 1
- 1/3 y = - 1/4 x + 1
-4y = -3x + 12
4y = 3x - 12
y = 3/4 x - 3
If you get both equations in this form it is evident that the slopes m are the same (parallel) but the y intercept's b are different (not the same line). Therefore no solution.
Answer:
see below
Step-by-step explanation: 5 20 15 28
3x + y = 23
3x – 2y = 8
O I should add, and the Xs will be eliminated. 3x + 3x = 6x NOT eliminated
O I should add, and the Ys will be eliminated. y + -2y = -y NOT eliminated
O I should subtract, and the Xs will be eliminated. 3x - 3x = 0x X is eliminated
O I should subtract, and the Ys will be eliminated. y - -2y = y NOT eliminated
Answer:
Yes, it is a function
Step-by-step explanation:
It passes the vertical line test, therefore it is a function.
6^2 = 36 is a perfect square.
