Answer:c
Step-by-step explanation: function 2 y-intecept is -5(when r=0), fuction 1 y-intecept:
p=-3/2*r-5 (r=0 because we looking for y-intecept)
p=0-5=-5
Asw= 2
7:1=7 x1=7
7-7=0+3=3
The answer is +3
1.Consider the system of equations. x-5y=2
3x-10y=11
(a) Jamar rewrote the first equation as –2x + 10y = –4. What justification did he have for doing this?
(b)Jamar combined the equation in Part (a) with the second equation in the system to get x = 7. Explain Jamar’s reasoning.
(c) What is the solution of the system? (d) How do you know, without graphing, that the graph of 4x – 15y = 13 passes through the point whose coordinates are the solution of the system?
Is a problem solving method that uses that fact that any number or expression can be multiplied by one without changing it's value.
