Check whether (0, -2) is solution of the equation x - 2y = 4 or not

Mathematics
1 answer:
kaheart [24]3 years ago
8 0

Answer:

Step-by-step explanation:

Plugin x = 0 & y = -2 in the LHS of the equation. After substituting, if you get the RHS, then this point is the solution of the equation.

x - 2y = 0 - 2*(-2)

         = 0 + 4

         = 4  = RHS.

(0,-2) is solution of the equation.

chubhunter [2.5K]

Answer:


Step-by-step explanation:

Statements                          Reasons

----------------------------------------------------------------

1. ∠V ≅ ∠Y                        Given

2. WZ bisects ∠VWY          Given

3. ∠VWZ ≅ ∠YWZ            Definition of Angle Bisector (2)

4. WZ ≅ WZ                         Reflexive Property

5. ΔVWZ ≅ ΔYWZ               AAS Theorem (1,3,4)

**In case you didn't know the definitions**

Angle Bisector - A line, segment or ray that divides an angle into two congruent angles

Reflexive Property - X = X

AAS Postulate -  If two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangle's are congruent

Question 7: Help Me Please
ehidna [41]

Answer:

m∠UQT = 52°
m∠UTQ = 42°
x = 1

Step-by-step explanation:

∠UQT is an alternate interior angle of ∠RSQ

Therefore, ∠UQT is 52°

∠UTQ is an alternate interior angle of ∠URS

Therefore, ∠UTQ is 42°

The diagonals of a parallelogram are congruent, so 4x + 1 is 5

  • 4x + 1 = 5
  • 4x = 4
  • x = 1

Given △ABC, AB=15, BD=9, AD ⊥ BC , m∠C=30° Find: The perimeter of △ABC.
Ann [662]

Answer:

48 + 12√3 units

Step-by-step explanation:

ALL LENGTHS MUST BE POSITIVE (I did this to avoid writing ± and showing that only + works)

1. Find AD (you'll find why later): 15² = 9² + AD² --> AD² = 144 --> AD =  12

2. 30-60-90: 12-DC-AC --> AC = 24, DC = 12√3 (side opposite of 90 is double side opposite of 30, side opposite of 60 is √3 times the opposite of 30)

P = AB + BD + DC + AC = 15 + 9 + 12√3 + 24 = 48 + 12√3 units
