51 times the difference between a number and 21 is equal to the number plus 58.
Lerok [7]

51(x - 21) = x + 58

<em><u>Distributive property</u></em>

51x - 1071 = x + 58

<em><u>Subtract x from both sides</u></em>

50x - 1071 = 58

<em><u>Add 1071 to both sides</u></em>

50x = 1129

<em><u>Divide both sides by 50</u></em>

x = 22.58

Please help! What is the function for the graph
Evgen [1.6K]

When x = 0 the value of the function is 2 so its either A or B.

When x = 1, y = 8 so substituting these values in A we get:-

8 = 2 * 8^1 = 16 so

its Not A. Try B:-

8 = 2 *4^1 = 8 which fits

Answer is choice B
