She has a 50 percent chance she flips the coin on tails.
Answer:
Y=2x+0
Step-by-step explanation:
First you have to find the slope of the graph or the rise over run, which in this case is 2
Then you have to find the y intercept, which is zeroSo the rule for thos graph is y=2x+0.
To double check our work take a random point on x axis. I chose the point 1,2
fill in the formula and you should get 2(1)+0=2 and therefore this Formula is correct
The answer is that they are the same height hope that helped and have a good day
Answer:
Hence, the number of 3-miles run Gavin went on last month=12.
and number of 5-miles run Gavin went on last month=13.
Step-by-step explanation:
'x' denotes the number of 3-miles run.
'y' denotes the number of 5-miles run.
Gavin went on 25 runs.
that means x+y=25-------(1).
also he total walked 101 miles that means in equation it could be written as:
3x+5y=101--------(2)
on solving equation (1) and (2) by method of elimination.
multiply equation (1) by 3 and subtract from equation (2) we get:
equation (1) transformed to 3x+3y=75
3x+5y=101
3x+3y=75
- - -
---------------
2y=26
⇒ y=13.
and putting value of y in equation (1) we get:
x=12.
Hence, the number of 3-miles run Gavin went on last month=12.
and number of 5-miles run Gavin went on last month=13.
Answer:
k ±16
Step-by-step explanation:
Evaluate x^2 + 8 x + k where x = -4:
x^2 + 8 x + k = k - 4 8 + (-4)^2
(-4)^2 = 16:
k - 4 8 + 16
8 (-4) = -32:
k + -32 + 16
Grouping like terms, k - 32 + 16 = k + (16 - 32):
k + (16 - 32)
16 - 32 = -16:
Answer: k ±16
