Answer:
(-2-h)^2+(-7-k)^2=r^2
Step-by-step explanation:
(x-h)^2+(y-k)^2=r^2 this is the normal equation now u just need to substitue those in it
Answer:
Equation:
.
It would take Martina 37 hours to earn $518
Step-by-step explanation:
✍️An equation that shows a proportional relationship between the time she spends babysitting (x) and amount of money she earns for babysitting (y) can be represented as
, where k = constant of proportionality.
Let's find k using any of the pairs given in the table of values. Let's use (1, 14).
Substitute x = 1, and y = 14 into
, and find k.


Substitute k = 14 into
.
✅The equation would be:
.
✍️Using the equation, we can find how many hours Martina needs to work in order to earn $518 she wants to use to buy a new phone.
Simply, substitute y = 518 in
.

Divide both sides by 14


✅Thus, it will take Martina 37 hours to earn $518
Answer:
x = 2
Step-by-step explanation:
To find the value of x, we simply need to use the know values for the lengths, widths, and perimeter of the rectangle.
The formula for the perimeter of a rectangle is as follows:
P = 2L + 2W
Where P is the perimeter, L is the length, and W is the width.
Let L = 7x + 5 and W = x - 3
Now, we will simply plug our values into the formula and solve for x.
P = 2L + 2W
36 = 2 ( 7x + 5 ) + 2 ( x - 3 )
36 = 14x + 10 + 2x + -6
36 = 16x + 4
32 = 16x
2 = x
Thus, we have found the value of x to be 2.
