I dont know what to do lol

Answer:

15 units

Step-by-step explanation:

The distance between two points can be found using the following formula:

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

Given points:

(-7, 5) and (2, -7)

<u>where:</u>

  • x₁ = -7
  • x₂ = 2
  • y₁ = 5
  • y₂ = -7

Substitute these points into the formula and simplify:

\sf d=\sqrt{(2-(-7))^2+((-7)-5)^2} \ \textsf{[simplify the radicand]}\\\\ d=\sqrt{(2+7)^2+(-12)^2} \ \textsf{[simplify]}\\\\d=\sqrt{(9)^2+(-12)^2} \ \textsf{[evaluate the power]}\\\\d=\sqrt{81+144} \ \textsf{[add]}\\\\d=\sqrt{225}\ \textsf{[simplify]}\\\\d=15

The distance between the two points is 15 units.

Find 4 consecutive odd integers whose sum is 232
VashaNatasha [74]
 4 consecutive odd integers...
x, x + 2, x + 4, x + 6

(x) + (x + 2) + (x + 4) + (x + 6) = 232
4x + 12 = 232
4x = 232 - 12
4x = 220
x = 220/4
x = 55

x + 2 = 55 + 2 = 57
x + 4 = 55 + 4 = 59
x + 6 = 55 + 6 = 61

so ur numbers are : 55, 57, 59, 61

We have a jewelry sale event where we are promoting a gold necklace at 33% off with an initial retail of $88.00. What would the
Andrej [43]
(Ignore the scatter plot thing)

Since the necklace is 33% off, you subtract 33% from 100% to get 67% (you’re only paying 67% of the initial price). You can then multiply 88*0.67 to get the sale price, which is $58.96. For the markdown dollars you can subtract 58.96 from 88 to get $29.04 (you saved $29.04 from the sale)
