This is a function since the cost equals the number of nails time the cost of each nail. So that is a function

<h3>Answer:</h3>

Yes, the given relation is a function

<h3>Step-by-step explanation:</h3>

Since it is obvious that the cost of nails varies according to the number of pounds of nails.

The cost cannot coincide with different number of pounds.

Say if a pounds cost x and b pounds cost y, then x cannot be equal to y untill a = b.

From this conclusion, we reach our decision that since each element of set input set will have a unique image in output set, the given relation is a function.

<em>Remember</em><em> that</em><em> </em><em>every</em><em> </em><em>function</em><em> </em><em>is </em><em>a </em><em>relation</em><em> </em><em>but </em><em>every</em><em> relation</em><em> </em><em>is </em><em>not </em><em>a </em><em>function</em><em>.</em>

Please help asap, djdbdjbf
Dovator [93]

Answer:

x = 20

Step-by-step explanation:

so we aren't give the angle across from 70, but we are given the degree on the outside, so if we take that and subtract it from 180 we will get the degree inside the triangle which is 70. (this also appears to be an isosceles triangle so it would be 70 anyway, but we can do this just to make sure.) Then, since all of the angles in the triangle add up to 180, we can subtract 140 (both 70 degrees) from it and we are left with 40. Divide 40 by 2 and you will get 20 which is the measure for angle x! Hope this helps
