PLEASE ANSWER ASAP!!
What is the solution to the system of equations below?
y =2/5x - 3 and x = –10

1. (-10, -7)
2. (-10, -1)
3. (-7, -10)
4. (-1, -10)

The answer is 1. Sub x= -10 into the equation of y

The solution to this equation is (-10, -7). Since y= 7 in the equation, (-10, -7) makes sense.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
