what is the domain of the function: {(1, 3); (3, 5); (5, 7); (7, 9)}? a. {1, 3, 5, 7, 9} b. {1, 3, 5, 7} c. {1, 9} d. {3, 5, 7,

B. 1, 3, 5, and 7 are x values. Domain is the x value.
Vary Directly: y = k*x
Vary Inversely: y = k/x
Because x and y vary directly, our equation will look like the first one.
y = k*x
With the inputted values:
-16 = k * 4
Now, to find k, isolate the variable
k = -16/4 = -4
Your final equation will then look like this:
y = -4 * x
3/4 times 2/2 is 6/8
3/4 = 6/8
To find the equivalent fracrion divide or multiply by the smae number to both the denominator and numerator that is equal to one (4/4; 5/5;67/67,etc.)
Answer:
6x214=1284
1284-3 is 1281
Step-by-step explanation:
1) A square has 4 congruent sides, and the perimeter is the sum of these 4 sides. So perimeter = 3x+3x+3x+3x, which can also be expressed by 4(3x), simplified, it equals to 12x.
2) x^2 + 6x + 8
3) x^2 - 4x - 12
