Answer:

d=13.

Step-by-step explanation:

d=\sqrt{(x_{2}-x_{1} ) ^{2} +(y_{2}-y_{1} ) ^{2}}

From question statement, x_{1} =-3   ,x_{2} =9

y_{1} =2  ,y_{2} =-3

put above values in the distance formula,we obtain

d=\sqrt{(9-(-3))^{2}+(-3-2)^{2}}

d=\sqrt{(12)^{2}+(-5)^{2}}

d=\sqrt{144+25}

d=\sqrt{169}

d=13

Write the equation of a circle with center (-3, 5) and a point on the circle is (1, 8).
ludmilkaskok [199]

Answer:

(x + 3)^2 + (y - 5)^2 = 5^2

Step-by-step explanation:

Well, the center origin of the circle is given (h,k) =  (-3,5).

Point on the circle is (x,y) = (1,8)

We have to find our radius as they gave us a point. from origin to the edge of the circle.

Using the formula: (x - h)^2 + (y - k)^2 = r^2

Plug in our (h,k) = (-3,5) and (x,y) =  (1,8) to solve for radius.

(x - h)^2 + (y - k)^2 = r^2

(1 - (-3))^2 + (8 - (5))^2 = r^2

(4)^2 + (3)^2 = r^2

16 + 9 = r^2

r^2 = 25

r = 5

A college student has $240 to use for laundry money. Each time he does laundry, he spends $7.50. Which equation represents the a
Lady bird [3.3K]

Answer:

B

Step-by-step explanation:

x = the number of times he does laundry.

Let's say he does the laundry 5 times then x = 5.

Each time costs $7,50.

If you want to know how much money he has spent after 5 times, you have to calculate 5 times $7,50. 7,5 times 5 = 37.5.

M stands for how much money he still has left from the 240 dollars.

If you apply the formula it would be 'M = 240 - 7.50x (7.50 times 5) = 240 - 37.5 = 202.5'

Therefore, the correct answer is B (M = 240 - 7.50x).
