Answer:

(2, 0 )

Step-by-step explanation:

Given the 2 equations

2x + 3y = 4 → (1)

3x - 7y = 6 → (2)

Multiplying (1) by 3 and (2) by - 2 and adding the result will eliminate x

6x + 9y =  12 → (3)

- 6x + 14y = - 12 → (4)

Add (3) and (4) term by term to eliminate x

0 + 23y = 0

23y = 0

y = 0

Substitute y = 0 into either of the 2 equations and solve for x

Substituting into (1)

2x + 3(0) = 4

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 )

Answer: The first step would be to multiply the first equation by 3 and the second by 2 so you can eliminate x.

Answer:

x=27, y=18

Step-by-step explanation:

Angle CB is 128, which means angle AC is 72. We can confirm angle O is also 72, since the lines are straight. Angle AM is 27, because AN is a right angle. 63+72+27= 162 180-162=18 Angle ND is 18.

Answer:

9x^2 -49

Step-by-step explanation:

We recognize that this is of the form

(a+b)(a-b) = a^2 - b^2

3x = a and 7 =b

(3x)^2 - 7^2

9x^2 -49
