Answer:
12
Step-by-step explanation:
you have 72 and 6
72 divided by 6 equals 12.
12 x 6 = 72
12 = x
Answer:
D.
Step-by-step explanation:
D. This contains an x^2 and is called a parabola ( curved line like a U).
Answer:
x = - 3
y = 4
Step-by-step explanation:
x + y = 1 | (-3)
x + 3y = 9
- 3x - 3y = - 3
x + 3y = 9
_____________
- 3x + x = 9 - 3
- 2x = 6
2x = - 6
x = - 3
- 3 + y = 1
y = 1 + 3
y = 4
Answer:
81 1/3 . . . . . (none of the offered choices is appropriate)
Step-by-step explanation:
According to the order of operations, expressions inside parentheses are evaluated first.
= 12[5^2 ÷ (25 -16) +4]
= 12[5^2 ÷ 9 + 4]
Exponentials are evaluated before multiplication or division.
= 12[25 ÷ 9 + 4]
Division is performed before addition
= 12[(2 7/9) +4]
= 12[6 7/9]
And finally, the multiplication is performed
= 72 +84/9 = 72 +9 1/3
= 81 1/3
_____
A Google search box can be relied upon to apply the order of operations when evaluating an arithmetic expression.
== == == == ==
If the problem is ...
... 12[6^2 ÷ (25 -16) +4]
then the result is A. 96.
Find an x value and f(x) is just it's y value. we can start with x=0
when x=0 y= -3
when x= 2 y= -2
and so on, choose easy to read numbers.
