Answer:

x=9y+127

y=79x+−43

Step-by-step explanation:

<em><u>steps</u></em><em><u> for x.</u></em>

3y−x3−2x=−4

Step 1: Add -3y to both sides.

−73x+3y+−3y=−4+−3y

−73x=−3y−4

Step 2: Divide both sides by (-7)/3.

−73x−73=−3y−4−73

x=9y+127

Answer:

x=9y+127

<em><u>steps</u></em><em><u> for y.</u></em>

3y−x3−2x=−4

Step 1: Add 7/3x to both sides.

−73x+3y+73x=−4+73x

3y=73x−4

Step 2: Divide both sides by 3.

3y3=73x−43

y=79x+−43

Answer:

y=79x+−43

ABCD is a rectangle. Find the length of each diagonal.ac=2(5a+1) bd=2(a+1).
Igoryamba
   
Rectangle diagonals are equal.

2(5a+1) = 2(a+1)
10a + 2 = 2a + 2
10a -2a = 2 - 2
8a = 0
⇒ a = 0

AC = 2(5a+1)  = 2(5 × 0 +1)= 2(0 + 1) = 2 × 1 = 2 <span> 
</span>BD = 2(a+1) = 2(0 + 1) = 2 <span>× 1 = 2
</span>
Ansver:   AC = BD = 2

Find the least positive angle measurement that is coterminal with -230°.
Alex Ar [27]
The answer is Letter C - 130<span>°
</span>
Coterminal Angles are angles that share a common terminal or end position. In finding the coterminal angle, you can add or deduct 360°. In this case, you are asked to get its positive coterminal angle. You will simply add 360° to -230°.

Solution: 360° + -230° = 130°

Sue Jones is insured for bodily injury in the amount of 10/20. She is at fault in an accident in which Albert Smith is injured.
Vlad1618 [11]
What you must do is add up the total amount of medical expenses:
 Albert's medical expenses total $ 12,000
 Sam's come to $ 8,000
 Adding we have:
 $ 12,000 + $ 8,000 = $ 20,000
 Sue Jones is insured for the amount of 10/20
 So:
 (10/20) * (20000) = 10000
 answer
 The insurance will pay $ 10,000

How do i solve for this?
Firdavs [7]

9514 1404 393

Answer:

  97.42 square units

Step-by-step explanation:

The area of a sector is given by ...

  A = (1/2)r²θ

where r is the radius (12.2) and θ is the central angle in radians. Here, you're given the central angle as 75°, so you need to convert that to radians.

  75° = (75°)×(π/180°) radians = (5/12)π radians

Then the area is ...

  A = (1/2)(12.2²)(5π/12) = 744.2π/24 ≈ 97.42 . . . square units

__

Equivalently, you can find the area of the circle in the usual way:

  A = πr² = π(12.2²) ≈ 467.59465

Then, multiply by the fraction of the circle that is shaded (75°/360°)

  sector area = (467.59465)(75/360) = 94.42 . . . square units
