If Sally already has 3 marbles and she finds 5 everyday. That means you add 5 until you get to 58. So in this case 5 times 11 is 55 + 3 is 58. Answer: It will take 11 days at this rate for her to have 58 marbles.

What is 4(1+5n)=-6n-14+8
crimeas [40]
4(1 + 5n) = -6n - 14 + 8

4(1 + 5n) = -6n -6

4 + 20n = -6n - 6

10 + 26n = 0

26n = -10

n = -10/26 = -5/13.

I believe this would be the solution to the question.

Use the distance formula to determine the distance between (-8,10) and (-6,7)
hjlf

Answer:

Distance: \sqrt{13} units

Step-by-step explanation:

The distance formula is d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} where:

  • d is the distance between points (x_1,y_1) and (x_2,y_2)
  • (x_1,y_1) are the coordinates of the first point
  • (x_2,y_2) are the coordinates of the second point

We are given that:

  • (x_1,y_1)=(-8,10)
  • (x_2,y_2)=(-6,7)

To determine the value of our distance, d, we plug in our given information into the formula and solve for

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

d=\sqrt{(-6-(-8))^2+(7-10)^2}

d=\sqrt{(-6+8)^2+(-3)^2}

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

d=\sqrt{4+9}

d=\sqrt{13}

Therefore, the distance between (-8,10) and (-6,7) is \sqrt{13} units.

See the attached graph for a visual.
