Answer:
The correct answer is option D. Dilation by a scale factor of 2 followed by reflection about the x-axis
X+y=12 -- 1
3x+2y=29 -- 2
(1)x2
2x+2y=24 -- 1
(2)-(1)
x=5
Sub x into 1
x+y=12
5+y=12
y=7
Her two numbers are 5 and 7
Answer:
<em>start with y</em>
y
<em>add 7</em>
y+7
<em>multiply by 3</em>
3(y+7)
<em>subtract 6</em>
3(y+7)-6
<u>therefore the answer is:</u>
3y + 21 - 6
=
3y + 15 or 3(y+5)
Step-by-step explanation:
The die is rigged, so "not 3" is not a possibility. Ruling out those branches of the tree, there are 4 possible outcomes, one of which is the desired outcome. So the probability is 1/4.
A fair die has six sides that are equally likely, so the probability of rolling more than 2 is always 4/6. The outcome of the first roll does not effect the outcome of the second roll.
The median is the number in the middle when all of the numbers are placed in order (from lowest to highest).
15; 17; 19; 42; 78; 85; 93
The answer in this case would be 42.
