Answer:
<h2>Slope = 1/2</h2>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
From the question the equation is
- 5x + 10y = 20
To find the slope we must first write the equation in the form above
- 5x + 10y = 20
Move - 5x to the right side of the equation
10y = 5x + 20
Divide both sides by 10
We have


Comparing with the general form of equation above
Slope / m = 1/2

Answer: it is a solution set
Step-by-step explanation:
The given system of simultaneous linear equations is expressed as
7x-3y=6 - - - - - - - - - -1
2x+y=11 - - - - - - - - - - - 2
We would eliminate x by multiplying equation 1 by 2 and equation 2 by 7. It becomes
14x - 6y = 12
14x + 7y = 77
Subtracting, it becomes
- 13y = - 65
Dividing the left hand side and the right hand side of the equation by - 13, it becomes
- 13y/13 = - 65/- 13
y = 5
Substituting x = 5 into equation 2, it becomes
2x + 5 = 11
Subtracting 5 from the left hand side and the right hand side of the equation, it becomes
2x + 5 - 5 = 11 - 5
2x = 6
Dividing the left hand side and the right hand side of the equation by 2, it becomes
x = 6/2 = 3
The answer is B because when yku combine like terms (x) 2/5 + 1/5 you get 3/6. Then when you simplify the equations, you turn -1/4 into -2/8 to match the 5/8. From there you just subtract 2/8 from 5/8 getting 3/8.
Answer:
The answer is 7
Step-by-step explanation:
It is 7 because when you multiply 6 times 7 equals 42 so the answer is 7
