Answer:

Option C is NOT a function.

Step-by-step explanation:

For these functions we will use subtraction as our example. With option A the pattern is:  -8, -7, -6, -5. Therefore option A is a function. With option C the pattern is: 3, 3, 3, 2. Therefore this is not a function. With option B the pattern is 0, 0, 0, 0. Therefore this is a function. With option D the pattern is: -6, -2, 2, 6. Therefore this is a function.

 This question can be done multiple ways, but this is just one of them.

In the problem 3/4 • N=1, n must be

Serggg [28]

3/4 x n=1......n equals 4/3.

In order for n to equal 1 you have to find a number that will make 3/4 a whole number after you multiply it. Usually in problems like these the answer is usually the fraction but flipped around. So 3/4 and 4/3....when you multiply the numerators you get 12 and when you multiply the denominator you get 12 so 12/12, which equals 1. hope that makes sense.

In getting the area of and equilateral triangle, you must first consider that all of its sides are congruent and that is 3 inches, so the formula in getting the area is height form its base so in getting its height you must use the pythagorean theorem by dividing the triangle so the hypotenuse of it is 3 and the base of 1.5inches, so the height is 4.77 inches then the area is 7.15 sqr.inch

the equation of the line a is given as y = -3/4 x -2. Suppose the line a is parallel to line b and lime t is perpendicular to li

Burka [1]

Answer: The equation for line b is $y = -\frac{3}{4}x + 5$

The equation for line t is $y= \frac{4}{3} x+5$

The attachment shows the original line in green, the parallel line b in red, and the perpendicular line t in blue.

Step-by-step explanation: Use slope intercept form, y = mx + b

The given coordinate, (0,5) is on the y-axis, so 5 will be the y-intercept of the equation. Keep the slope of the original equation and substitute the new value for "b"

To write the equation for line t

Both lines share the y-intercept, (0,5) so the "b" term will be the same. The slope of a perpendicular line is the reciprocal of the original slope with the opposite sign.

So invert 3/4 to become 4/3 and change the negative sign to positive.

The resulting equation is y = 4x/3 + 5
