Answer:
I think its A
Step-by-step explanation:
This system has one solution y=8x+9, y=x^2+4x+13. What is the y coordinate
y=8x+9<= y=8x+9 <== 8x+9: m=8
y=x^2+4x+13<= y <==x^2+4x+13: minimum (-2,9)
y=8x+9 and y.No solution
Answer:
√
42 lies between 6 and 7
Step-by-step explanation:
We know that √
42 will lie between √
36 and √
49
And √
