Answer:
x=10/3 y=17/3
Step-by-step explanation:
Use substitution to solve your equation. Plug in y=2x-1 into y=1/2x+4. This makes (2x-1)=1/2x+4. Simplify this to get 3/2x-1=4. Simplify it again to get 3/2x=5. No one likes fractions so multiply both sides by 2 to get 3x=10. Simplify this and get x=10/3. Plus 10/3 into one of the equations. You can pick anyone but I picked y=2x-1. Because you know x=10/3, you put y=2(10/3)-1. Simplify this and get y=20/3-1. Convert 1 into a fraction and get y=20/3-3/3. Simplify this and get y=17/3.
Therefore,
x=10/3 y=17/3

Answer:T
Step-by-step explanation: Every Input should correspond to exactly one output. Every input should only have one output. If 2 outputs correspond to the same # for the input, then it is not a function like in this example where 4 and -4 correspond to one input # which is 3 and the same with the 5's
Answer:
option d
Step-by-step explanation:
Given that a coin is tossed 5 times. Assuming it is a fair coin, head and tail are equally likely.
If we toss 5 times, the number of heads can be either 0 or 1 or 2...5.
Number of outcomes that have 2 heads
=out of 5, two heads and three tails
=5C2
=5(4)/2
=10
So answeris 10
Option d is right answer
