Answer:

r = 4

Step-by-step explanation:

If we clearly observe a point and the slope of the line are given.

Point=(5, -6)   slope= -5

We know that the equation of the line having slope m and passing through point (x_{1} , y_{1})  is

y-y_{1}=m(x-x_{1})

Now the equation of the line is y-(-6)=(-5)*(x-5)

y+6=-5x+25

5x+y=19

Now given that (3,r) lies on this line

5*3+r=19

r = 4

Janet and Nadia each play basketball, Nadia has won twice the number of games Janet has, Is it possible for Janet to have won 10
Lapatulllka [165]

Answer:

It is not possible for Janet to have won 10 games.

Step-by-step explanation:

Let be "x" the number of games Janet won.

We know that Nadia has won twice the number of games Janet has and the sum of the games Nadia and Janet have won together is 24.

Then, we express this situation with this equation:

So, let's check if it is possible for Janet to have won 10 games. Substitute  into the expression:

Therefore, it is not possible for Janet to have won 10 games.

Measure of ∠B is 110°

Step-by-step explanation:

  • Step 1: Find ∠B of the parallelogram.

In a parallelogram, opposite angles are equal.

⇒ ∠B = ∠D

⇒ ∠B = (5x + 10)°

  • Step 2: Use theorems of quadrilaterals to form equations to find x and y.

Now, angles in a parallelogram are equal to 360°.

⇒ ∠A + ∠B + ∠C + ∠D = 360°

⇒ (3x + y)° + (5x + 10)° + (5y + 20)° + (5x + 10)° = 360°

⇒ 13x + 6y + 40° = 360°

⇒ 13x + 6y = 320°  ------ (1)

Also, adjacent angles in a parallelogram are supplementary.

⇒ ∠A + ∠D = 180°

⇒ (3x + y)° + (5x + 10)° = 180°

⇒ 8x + y = 170° ----------- (2)

  • Step 3: Solve the 2 equations to find x and y.

13x + 6y = 320

48x + 6y = 1020  (After multiplying eq. 2 with 6 to make coefficients equal)

Subtract (2) from (1)

⇒ -35x = -700

∴ x = 20

⇒ (5x + 10)° = 100 + 10 = 110°
