Answer: OPTION B.
Step-by-step explanation:
Given the following System of equations:

You can use the Elimination Method to solve it. The steps are:
1. You can mutliply the second equation by -3.
2. Then you must add the equations.
3. Solve for the variable "y".
Then:

4. Now that you know the value of the variable "y", you must substitute it into any original equation.
5. The final step is to solve for "x" in order to find its value.
Then:

Therefore, the solution is:

Answer:
y = 8/5x
Step-by-step explanation:
I'm assuming that they're asking for the equation in point-slope form.
The formula is y=mx+b where:
m = slope
b = y intercept
However, the y intercept is just (0,0) so b = 0
To find the slope we already have 2 given points: (0,0) and (5,8)
To find slope you do rise/run and you get 8/5
Substitute the slope & y intercept in the formula:
y = 8/5x
Let me know if I'm wrong!!
Answer:
a^2+b^2=c^2 look below
Step-by-step explanation:
Count the squares so
3^2+4^2=5^2
3*3=9
4*4=16
5*5=25
9+16=25 and it does check out
this should help if u need more explanation ill be more then happy to explain to you
