x=-8
Answer:
Step-by-step explanation:
You use the given information in the standard form of a circle equation to solve for r. We have (h, k) which is the center and a point (x, y). The standard equation for a circle is
Filling in:
and
and
Now that we used the coordinate we don't need it anymore. x and y go back into the equation as x and y, not numbers. We do, however, need the center. Writing the equation:
which is choice D.
To solve use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
REMEMBER: IF A STEP IS NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .
14 + 18 ÷ 2 x 18 - 7
Now comes the problematic part, in which many people get confused. Although in the PEMDAS order it shows multiplication before division, you must remember that multiplication and division are "paired." This means that you will apply these two operations in the order they come first in the expression as you read it from left to right. In this case that would be division first then multiplication.
NOTE: This rule also applies when you are dealing with addition and subtraction in the same expression
Division
14 + 18 ÷ 2 x 18 - 7
18 ÷ 2 = 9
14 + 9 × 18 - 7
Multiplication
14 + 9 × 18 - 7
9 × 18 = 162
14 + 162 - 7
Addition
14 + 162 - 7
14 + 162 = 176
Subtraction
176 - 7
= 169

The sneakers originally cost=Sale Price/0.75.
Given that,
Sale of Paris sneakers This costs 75% of what it did before.
We have to find how much did the sneakers originally cost.
Original pricing refers to the cost determined by the MSRP (manufacturer's suggested retail price). Even if the original and current prices occasionally overlap, the initial price was frequently always less expensive than the current price.
You divide the sale price of the sneakers by the % to find the answer to this puzzle.
Sale Price=(Original Price)×(Percentage)
Sale Price/Percentage=Original Price
Sale Price/0.75=Original Price
Therefore, The sneakers originally cost=Sale Price/0.75.
