10x + 2y - 6 = 0

Multiply 5x + y - 3 = 0 by 2

2(5x + y - 3 = 0) = 10x + 2y - 6 = 0

Answer: The resulting equation are,

3x - 2y - 7 = 0

10x + 2y - 6 = 0

Step-by-step explanation:

Since, for solving a system of equations by the elimination method we either add or subtract the equations to get an equation in one variable.

For this we find out the L.C.M. of the coefficients of that variable which we want to eliminate.

Here, the given equations are,

3x - 2y - 7 = 0  -----(1)

5x + y - 3 = 0 -----(2)

For eliminating y,

The coefficient of y in equation (1) = 2,

And, the coefficient of y in equation (2) = 1

L.C.M. (2, 1) = 2,

Thus, we make 2 as the coefficient of y in both equations,

For this we multiply equation (2) by 2 and equation (1) by 1,

Resultant equations are,

3x - 2y - 7 = 0

10x + 2y - 6 = 0

Select all the ordered pairs that make this statement true?
Ierofanga [76]

Answer: (24,-9)

(0,9)

(4,6)

Step-by-step explanation:

3x + 4y = 36

Using (3,-2) will be:

= 3(3) + 4(-2)

= 9 - 8 = 1

Using (1,7) will be

= 3(1) + 4(7)

= 3 + 28 = 31

Using (0,0) equals to 0

Using (24,-9) will be:

= 3(24) +4( -9)

= 72 - 36 = 36

Using (0,9) will be:

= 3(0) + 4(9)

= 0 + 36 = 36

Using (4,6) will be:

3(4) + 4(6)

= 12 + 24

= 36

Using (-12,18) will be:

= 3(-12) + 4(-18)

= -36 - 72

= -108

The correct options are (24,-9), (0,9 and (4,6)

The measure ∠BQS of is 80°. What is the m∠NQS? 42° 48° 128° 32°
fomenos

Answer:

m<NQS = 32°

Step-by-step explanation:

Given:

m<BQS = 80°

m<BQN = 48°

Required:

m<NQS

SOLUTION:

Angle BQN and angle NQS are adjacent angles having a common line, QN, and a common corner point, Q.

Therefore:

m<BQN + m<NQS = m<BQS (angle addition postulate)

48° + m<NQS = 80° (substitution)

m<NQS = 80 - 48° (Subtraction of 48 from each side)

m<NQS = 32°
