Answer:

Yes, there is a constant of variation

Step-by-step explanation:

Let's see, we have a linear equation that is as follows:

<em>y = 26.2 * x. </em>

The first thing is to say that there is a constant of variation and it is the constant number of the equation, that is 26.2. And second to mention that it is the reason (or quantity, whether proportional or direct) for which the input data (i.e. x) and the output data (i.e. y) vary.

A square with sides x ft long has a perimeter of 34 1/2 ft. How long are the sides of the square
scoundrel [369]

Answer:

8.625 ft for each side.

Step-by-step explanation:

This one's pretty simple. It's a square, so all of its sides are the same length. It's perimeter is given as 34.5 ft, so all you have to do is divide 34.5 by 4 since squares have 4 sides. 34.5/4 is 8.625, which, rounding to the nearest 1/100th, is 8.63. Rounding to the nearest 1/10th it's 8.6, and rounding to the nearest 1th  is 9 (although i doubt saying 1th is right, but just because).

On a coordinate plane, a line with a 90-degree angle crosses the y-axis at (0, 1), the x-axis at (1, 0), turns at (3, negative 2
lapo4ka [179]

Answer:

maximum value of y = 3

Step-by-step explanation:

line Starts at -4 , 0   & turns at - 1 , 3

Slope = (3 - 0)/(-1 -(-4)) = 3/3 = 1

y = x + c

=> 0 = - 4 + c => c = 4

=> y = x + 4

line after turning crosses the y-axis at (0, 2) and the x-axis at (2, 0)

slope of this line :  (0-2)/(2-0) = -1

y = - x + c

2 = 0 + c => c = 2

=> y = - x + 2

=> y = 2 - x
