Megan has $45.12 in her purse. She spends $7.89 for lunch and $21.25 for a pair of sunglasses.

tekilochka [14]

Answer:

15.98 dollars

Step-by-step explanation:

its really easy

we need to subtract the total amount that she has spent from the total amount that she had in her purse

the total amount in Megan's purse=$45.12

total amount that Megan spent=$7.89+$21.25 =$29.14

now,

the exact amount that Megan has left = $45.12-$29.14=$15.98

(9,5) and (4,-7) find the distance between two points

Pani-rosa [81]

Answer:

13 units

Step-by-step explanation:

Use the distance formula, d = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$ , where (x2, y2) and (x1, y1) are two different points on the line.

Plug in the values:

d = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$

d = $\sqrt{(9 - 4)^2 + (5 + 7)^2}$

d = $\sqrt{5^2 + 12^2}$

d = $\sqrt{25 + 144}$

d = $\sqrt{169}$

d = 13

{(-9,3) (5,-6) (3,-1), (-6,5), ?}Which ordered pair can replace the missing value and make the set if ordered pairs NOT a functi

Nookie1986 [14]

$\text{Slope}=\frac{-1--6}{3-5}=\frac{5}{-2}$ $\begin{gathered} y-y_1=\frac{5}{-2}(x-x_1) \\ \\ y--6=\frac{5}{-2}(x-5) \\ \\ -2(y+6)=5(x-5) \\ -2y-12=5x-25 \\ 5x+2y=25-12 \\ 5x+2y=13 \end{gathered}$

The missing values are (-6, -9) ( The last option)

Explanation:

x= - 6 has already produced the value of y as 5, the only pair in the given option the make the given ordered pairs NOT to be a function is (-6, -9) since it will give the value of y to be - 9.
