Answer:
the second option is the correct answer
Answer:
Step-by-step explanation:
1 in²=6.45 cm²
598 cm²=x in²
1 in² x in²
______ = _______
6.45cm² 598cm²
Cross multiply
6.45x=598
divide both sides by 6.45
x=92.7 in²
Answer=92.7 in²
Let x be the time she ran and y be the time she walked
then distance ran = 25x and distance walked = 5y
so 15x + 5y = 42
and x + y = 4
* second equn. by -5:-
-5x - 5y = -20
add this to the first equn:0
10x = 22
x = 2.2
distance she ran = 2.2 * 15 = 33 km
Answer:
B. y = (x + 3)^2 - 17
Step-by-step explanation:
When Andy completes the square, he adds and subtracts the square of half the x-coefficient. That is, he adds and subtracts (6/2)² = 9:
... y = x² +6x +9 -8 -9
... y = (x² +6x +9) -17
... y = (x +3)² -17 . . . . . . . . matches selection B
I would first put these two points on a graph, they are pretty far apart but i know that the answer is on this question somewhere, so we start counting the amount of squares it takes to get from point A to point B, I got an answer result of 7 squares, so I conclude that the answer is 7
