5. Solve using any method. y = -x + 8 y=x+4

vlada-n [284]

Answer:

Step-by-step explanation:

$\bold{ELIMINATION\ METHOD}\\\\\left\{\begin{array}{ccc}y=-x+8\\y=x+4&\TEXT{change the signs}\end{array}\right\\\underline{+\left\{\begin{array}{ccc}y=-x+8\\-y=-x-4\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad0=-2x+4\qquad\text{add}\ 2x\ \text{to both sides}\\.\qquad2x=4\qquad\text{divide both sides by 2}\\.\qquad\boxed{x=2}\\\\\text{Put it to the second equation}\\y=2+4\\\boxed{y=6}$

$\bold{SUBSTITUTION\ METHOD}\\\\\left\{\begin{array}{ccc}y=-x+8&(1)\\y=x+4&(2)\end{array}\right\\\\\text{Substitute (1) to (2)}\\\\-x+8=x+4\qquad\text{subtract 8 from both sides}\\-x=x-4\qquad\text{subtract}\ x\ \text{from both sides}\\-x-x=-4\\-2x=-4\qquad\text{divide both sides by (-2)}\\\boxed{x=2}\\\\\text{Put it to the second equation}\\y=2+4\\\boxed{y=6}$

Does the point (-5, 3) satisfy the equation y = x − 8?

o-na [289]

No. This is because you can plug it in and see if it is true. Meaning...
3=-5-8
3=-13
3 is not equal to -13. Therefore the point does not satisfy the equation

You bought your current house 10 years ago for £55,000. There are currently three similar properties for sale on your street. Pr

galben [10]

Answer:

The house could be sold between £ 77,000 and £ 79,500

Step-by-step explanation:

Cost of the house = £ 55,000

40% profit on the amount paid for the house = 40% * 55,000 = 0.4 * 55,000 = £ 22,000

Suggested price with at least 40% profit = £ 55,000 + £ 22,000

Suggested price with at least 40% profit = £ 77,000

Properties price on the same street:

Property 1 £75,000

Property 2 £80,000

Property 3 £83,500

Mean of these prices = (75,000 + 80,000 + 83,500) / 3

Mean of these prices = 238,500 / 3

Mean of these prices = £ 79,500

Therefore the price could be between £ 77,000 (40% profit on the amount paid for the house 10 years ago) and £ 79,500 (the mean price of the properties currently for sale on the same street)
