Well i think is better expressed if x^2=9.then x=3, that will be better expressed. Now the converse if clearly false, since if x^2<span>=9</span> it is possible that <span>x=−3. I hope this is useful for you</span>
Answer:
21
Step-by-step explanation:
27÷3 is 9 and 21÷3 is 7
M(slope)= -5/4 point-slope(y-y1=m(x-x1)) so it would be y-5= -5/4(x+4)
Answer:
x = 8
Step-by-step explanation:
10x - 2 (x + 6) = 52
Let X become 8
10 (8) - 2 (8 + 6) = 52
80 - 2 (14) = 52
80 - 28 = 52
52=52
