Answer:
y = -1/2 (4 x + 2)
Step-by-step explanation:
A system of two equations with no solution will consist of equations for <em>parallel lines</em>. The line will be parallel if they have the same slope (x-coefficient) and different y-intercepts.
The given line has a slope of -2, so eliminating the last two choices.
The first two choices can be expanded to slope-intercept form:
y = negative 2 (x minus one-half) ⇒ y = -2x +1 . . . same as given line
y = negative one-half (4 x + 2) ⇒ y = -2x -1 . . . parallel line
There will be no solution if another equation is ...
y = -1/2(4x +2)
Answer:
To use the elimination method one coefficient of either x or y must be the same number with opposite signs, so the ordered pair is (-10, -8)
Step-by-step explanation:
2(-x+y=2) Make one of the coefficients equal, with opposite signs.
2x-3y=4 Combine equations.
-y=8 Solve, y=-8
Then find x, -x-8=2
-x=10, so x= -10
(-10, -8) is your answer.

Answer:
£10
Step-by-step explanation:
There may be a far easier way to do this, but this is how I did it and still came up with the correct solution.
-Assuming they buy at least 15 bags, they will get a 20% discount.
-20% discount would mean they only pay 80% of the original price. 80%=.80
-let x represent number of bean bags
£50 per bean bag multiplied by sale price .80, plus cost of coffee machine £370 must be equal to or less than £1300.
(50x)(.80) + 370 = 1300
Simplify:
40x + 370 =1300
Subtract 370 from both sides
40x = 930
Divide both sides by 40
X=93/4
Simplify fraction
23 1/4
=23.25
But since they cant buy .25 (quarter) of a bean bag, we reduce* to nearest whole number. We can not increase* to nearest whole number as this would exceed their budget.
23 bean bags. They can buy 23 bean bags at £40 each + coffee machine for £370.
£40(23) + £370 = £1290
£1300-£1290=£10
I hope this helps!
