Find the value or values of y in the quadratic equation y2 + 4y + 4 = 7.

Answers

If we move 7 to one side, we have (y^2 + 4y -3) = 0. From this form, we can apply the quadrati formula to solve for the values of y. To recall, quadratic formula is [ -b ±√ (b² - 4ac) ]/2a. For our equation, we have a =1, b = 4, and c = -3. If we plug this in, we have y to have approximate values of -2 - sqrt(7) and -2 + sqrt(7).

If the ones digit of a number greater than 1 is 0,what factor or factors must that number have

Answers

If the units digit is zero, then you have an even number ...
' 2 ' must be one of its factors.

It must also have two or more places ... it's greater than 9.
If it had only one place, and its units digit were zero, then
the whole thing would be zero.

Since it has two or more places, 5 and 10 are also factors.

Four sisters bought a present for their father. They received a 10% discount on the original price of the gift. After the discount was taken, each sister paid $9.00. What was the original price of the gift?

Answers

Answer:

The original price of the gift was $40.

Step-by-step explanation:

Let the original price of the gift be = x

Discount of 10% on the gift and each sister paid $9 means a total of $4*9=36$ dollars

We can write this information mathematically like :

$x-0.10x=36$

Solving for x now;

$0.90x=36$

x = $40

So, the original price of the gift was $40.

9 dollars represents 90% of the cost. Divide 9 by 0.90 to get the original price, 10 dollars
