Step-by-step explanation:
2:3 And. 6:9
3:4 And 9:12
8:5 and 16:10
1:2. And 3:6
Answer:
A, B
Step-by-step explanation:
Not C, D, E, because they show two points with the same x-coordinate but different y-coordinates.
In a function, each x is paired with <u>just one</u> y.
The graph of a function will never have two or more points <u>stacked verticall</u>y.
Answer:
8^(7), which is 2097152
Step-by-step explanation:
8^(4) × 8^(3)
= 8^(4+3)
= 8^(7)
= 2097152
Answer:
for the perimeter to be made into a equation it would take the equation
2(3x - 5) + 2(2x + 1)
And for the perimeter to equal 42 x would have to equal 5
Step-by-step explanation:
so first of all we have to find our equation to equal 42:
2(3x - 5) + 2(2x + 1) = 42
you then multiply 2 for both parentheses:
(3x * 2) + (-5 * 2) + (2x * 2) + (1 * 2) = 42
so its now:
6x -10 + 4x + 2 = 42
now your going to add variables to variables and numbers to numbers:
(6x + 4x) + ( -10 + 2) = 42
to get:
10x + (-8) = 42
Now your going to add 8 to both sides:
10x + (-8) = 42
+8 +8
Giving the equation:
10x = 50
now you divide both sides by 10 to get:
10x/ 10 = 50/10
x = 5
to solve you put 5 in place of the variable x:
2(3*5 - 5) + 2(2*5 + 1)
2(15 - 5) + 2(10 + 1)
20 + 22 = 42
So x equals 5 if the perimeter equaled 42
