Answer:
The answer (using BEDMAS) is 27
Step-by-step explanation:
The equation 9 x [(18+2) ÷ 5 - 1] is solved using BEDMAS or PEDMAS
First solve the smaller bracket
18 + 2 = 20
So then it becomes 9 x [20 ÷ 5 - 1]
Do the division inside the bracket next
20 ÷ 5 = 4
Then it becomes 9 x [4 - 1]
Do then subtraction within the bracket
4 - 1 = 3
Then it becomes 9 x 3
Finally solve 9 x 3 which equals 27
3/4 x 2/3 = 6/12 6/12=1/2
So the square root of 5 (C.)
The answer should be C. y=-3x+7
use the formula y=mx+b where mx is the slope and b is the y-intercept.
in this case, the slope is decreasing by 3 so -3 would fit in for mx. if you look on the y-int you’ll see that the value is positive 7.
when you put this together, you’d get the equation y=-3x+7
hope this helps.
