Answer:
line of reflection was across the -2 line on the x-axis
Step-by-step explanation:
the y points on all of the given points are the same distance from each other to the -2 line. (ie. (-5,2) and (-5,-6) = the 2 is 4 places away from -2 and -6 is 4 places away from -2.) making the reflection point -2 because it is the halfway point for all y values. It is on the x-axis because it is said it is a horizontal line. If it was vertical it would be on the y-axis.
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
hope this helps :)
<u>Answer:</u>
<u>ii) £120</u>
<u>iii) £2,400</u>
<u>a) 10 workers</u>
<u>c) 4 workers more to be employed.</u>
<u>Step-by-step explanation:</u>
ii) To find the buying price we deduct 20% (percent) from the selling price of £150.
= 20/100 x 150
= £30 (Next we substract this value from the selling price of £150) = €150 - £30 = £120
iii) A 12% interest per annum Implies a 12 percent of the borrowed amount of 20,000, which is calculated as
12% or 12/100 x 20,000 = £2,400
a) Put simply, we create an equation for the problem.
4 men * 10 days = 40 man days.
X men * 4 days = 40 man days.
Let's substitute the equation:
(X/ 4) * (4/ 10) = 40 / 40
(X/4) * 0.4= 1 (collect like terms)
0.4 * x = 4
0.4x/0.4= 4/0.4
x = 10 workers.
(c) 4 extra workers to would need to be employed since we have six already available (10-6=4).
