Need help with question 11 and 12
qaws [65]

Answer:

  11.  your choices are correct

  12.  132°

Step-by-step explanation:

11. The given equations can be (re)written to slope-intercept form. Only those lines with a slope of 2 will be parallel to the given line.

  A: y = 2x -8 . . . . . slope = 2, an answer

  B: y = -2x +1 . . . . . slope = -2, not an answer

  C: y = -2x +7 . . . . .slope = -2, not an answer

  D: y = 2x +2 . . . . . slope = 2, an answer

  E: y = -2x -9 . . . . . slope = -2, not an answer

__

12. The marked angles are supplementary, so ...

  (3x -6)° +(x +2)° = 180°

  4x -4 = 180 . . . . . . . . . . . divide by °, collect terms

  x -1 = 45 . . . . . . . divide by 4

  x = 46 . . . . . . . . . add 1

Now, we can find the angle of interest.

∠PQR = (3x -6)° = (3·46 -6)°

∠PQR = 132°

In 6 years, Mariya will be as old as Vikram is now. In 2 years, Vikram will be three times older than Mariya. Find their ages no
Damm [24]

Answer:

Mariya is 1 year old

Vikram is 7 years old

Step-by-step explanation:

Here, we want to know the present ages of Mariya and Vikram.

Let the present age of Mariya be M and the present age of Vikram be V

From the question, we are told that in 6 years time, Mariya will be as old as Vikram is now

Thus, mathematically;

M + 6 = V ••••••(i)

Furthermore , in 2 years time Vikram will be 3 time older than Mariya

Mathematically;

( V + 2) = 3( M + 2)

V + 2 = 3M + 6

V = 3M + 6-2

V = 3M + 4 •••••••(ii)

So let’s equate the V

3m + 4 = m + 6

3m -m = 6-4

2m = 2

m = 1

But V = m + 6

V = 1 + 6

V = 7
