Hey there! :)

There are 3 pennies
There is a total of 18 coins; 3 + 5 + 4 + 6 = 18

3 ÷ 18 = 0.16666666667 = 0.17

Your answer is 1/6 or 0.17

Hope this helps :)

Need help on number 1, 5 and 7

zimovet [89]

Answer:

1) y = (x + 8)² + 7; 5) y = (x - 6)² + 10; 7) y = (x - 3)² - 4

Step-by-step explanation:

Complete the square in order to figure these out. To complete the square, use the formula [½B]². Each time you do this, you get a perfect trinomial in the form of a product of two monomials [h], then you have to figure out how much more to deduct from or add on to your C they gave you in each exercise [k].
