Answer:
4
Step-by-step explanation:
Recall a linear function, is a line on a graph made up of an infinite amount of points which satisfy the relationship. That means at x=3 there is a specific point on the line with an output. The value of a function at x=3 asks, what is the output y value for the input x value?
To find it, we locate 3 on the x-axis. We draw a vertical line directly to the line following the grid line. We mark the point on the line. We then draw a horizontal line directly to the y-axis following the grid line. The point we hit on the y-axis is the value of the function.
Here it is 4.
5(x - 4) = 12 - 3x
5x - 20 = 12 - 3x
2x - 20 = 12
2x = -8
x = -4
Answer:
, or approximately 8.6
Step-by-step explanation:
By creating a right triangle as shown, we see that the given line is the hypotenuse of a right triangle with legs of lengths 5 and 7. By the Pythagorean Theorem, the length of the line is 
.
Answer: if its a multiple of a 345 triangle then its congruent x is 36 if othersides ate multiples of 20 ie
Sides are
