Answer:
The answer for 10 is y= -4x+2
If the slope is exactly the same but the y intercept is different then it will be parallel
The answer for 11 is y-5=-3/2 (x-1)
Step-by-step explanation:
Answer:
n = 5
Step-by-step explanation:
1) Use power rule: 
.
2) Cancel the base of z on both sides.
2n = 10
3) Divide both sides by 2.
4) Simplify 
to 5.
n = 5
Answer:
Hey there!
This is because the theoretical probability is different from the experimental probability. The theoretical probability is what is expected, but the experimental probability is what actually happens.
Hope this helps :)
Let y= years ago when dad's age was 4 times son's age
60-y=4(30-y)
60-y=120-4y
-y+4y=120-60
3y=60
y=60/3
y= 20 years ago
Then 30-20= 10 yrs. old, the boys age when his dad was 40 years old.
There are many ways to answer this question, but one example is 13 + 70 = 83
