Using finite difference, the answer is cubic. Apologies if I’m wrong
Answer:
x = 1 y = 3 z = 1
Step-by-step explanation:
(1) x - 3y - z = -9 (2) -2x + y + 2z = 3 (3) 2x + y + 3z = 8
2x(1) <u>2x - 6y - 2z = -18</u> (2) <u>-2x + y + 2z = 3</u>
- 5y = -15 2y + 5z = 11
y = 3 2(3) + 5z = 11
6 + 5z = 11
5z = 5
z = 1
x - 3(3) - 1 = -9
x - 9 - 1 = -9
x - 10 = -9
x = 1
Note: If you write your equations across your paper, then the work can just flow down the paper. It makes it so much easier to show the work you have done. OK?
♥ To solve find how much this will cost
AFTER the price increases.
♥ Solve:
Multiply the original price as it is by: <span>1.057 (5.7 as a decimal would be 0.057, but as i said to keep the original price, the 1 will keep it there.)

Final answer: <span>
$195.54</span>
Answer:
- 6/5
Step-by-step explanation:
To find the slope
m = ( y2-y1)/(x2-x1)
= ( -5-1)/(2- -3)
= (-5-1)/(2+3)
- 6/5
Answer:
Not simplified: 12:30
Simplified: 1:5
Step-by-step explanation:
We have 12 League A cards and 30 total.
So, 12:30.
But we can divide by 6 and reduce it to its simplest form:
1:5
