Answer:
19
Step-by-step explanation:
The equation has "absolute value" , "addition", "subtraction", "division", and "multiplication", and "parenthesis".
The order we follow here would be:
PEMDAS, which is "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction"
Also, note, we can do absolute value first, before these.
Now let's simplify using PEMDAS:
So the answer is 19 (note: i used "/" sign for "division")
To distribute the 2/3, this is what you do.
2/3[8(5-2)^2 + 3*2] = (2/3)(8)(5-2)^2 + (2/3)(3*2) =
Now you can continue. You need to follow the correct order of operations.
= (2/3)(8)(3^2) + (2/3)(6)
= (2/3)(8)(9) + 4
= (2/3)(9)(8) + 4
= (6)(8) + 4
= 48 + 4
= 52
This is how I would have done it.
2/3[8(5-2)^2 + 3*2] =
= 2/3[8(3)^2 + 6]
= 2/3[8 * 9 + 6]
= 2/3[72 + 6]
= 2/3[78]
= 2 * 1/3(78)
= 2 * 26
= 52
Answer:
9
Step-by-step explanation:
6+x x=3
6+3=9
3 to the -2 power is basically 3x-3, which is -9, and -5 to the -3 power is (-5)(-5)(-5) which is equal to -125. hope that helped you out, bud!
Answer:
7.(1,0) and (-4,0)
8. (-3,0) and (-2,0)
Step-by-step explanation:
7.
When the function is equal to zero, we are looking for the zeros, or the x intercepts
Where it crosses the x axis are 1 and -4
(1,0) and (-4,0)
8. When the function is equal to zero, we are looking for the zeros, or the x intercepts
Where it crosses the x axis are -3 and -2
(-3,0) and (-2,0)
