Answer:
3 and -4
Step-by-step explanation:
this is simple but difficult
let the number be x and second number be y
3x + 2y=1
x-y/2=5
from the 2nd equation
x-y/2=5
x=5+y/2
substitute value for x into equation 1
3x + 2y=1
3(5+y/2) + 2y= 1
15 +3y/2 +2y=1
15 + 7y/2=1
7y/2= 1 - 15
7y/2=-14
cross multiply
7y= -28
y= -28/7
y= -4
therefore second number is -4
substitute value for y into 1st equation
3x + 2y=1
3x + 2(-4) = 1
3x - 8= 1
3x= 1+8
3x= 9
x= 9/3
x= 3
therefore first number is 3
therefore two numbers are;
3 and -4
Answer:
<em>(6,3), last option</em>
Step-by-step explanation:
<u>Symmetry To A vertical line</u>
If the point Q (unknown) is symmetric to point P(2,3) with respect to x=4, it means it's located at the same distance to the line as P while keeping the same y-coordinate.
The point P has a distance of 4-2=2 units with respect to x=4. Q must have its x coordinate equal to 4+2=6, and keeping the y-coordinate equal to 3
The coordinates of Q are (6,3), last option

Step-by-step explanation:
The probability that the sum of Michelle's rolls is 4 is 0.083
∴ P(A)=0.083
Step-by-step explanation:
Given that Michelle is rolling two six-sided dice, numbered one through six.
To find the probability that the sum of her rolls is 4:
∴ n(s)=36
Let P(A) be the probability that the sum of her rolls is 4
Then the possible rolls with sums of 4 can be written as
n(A)=3
The probability that the sum of her rolls is 4 is given by
=0.083
∴ P(A)=0.083
∴ the probability that the sum of Michelle's rolls is 4 is 0.083
