Answer:
Correct answer is option D.
Step-by-step explanation:
Given that 
in the image 1 attached.
If we have a look at the image attached, the coordinates are:
<em>To find reflection</em> of a point across any line, the distance of points from the line must be same.
Point A(1,1) lies on the line x = 1, so its reflection A' will be at the same point A'(1,1).
Point C(2,5) is at a distance 1 from x = 1 on right side, so C' will be 1 distance on the left side of x = 1 i.e. 1 will be subtracted from its x coordinate.
i.e. C'(1 - 1, 5)
C'(0, 5)
Point B(4, 1) is at a distance 3 from x = 1 on right side, so B' will be 3 distance on the left side of x = 1 i.e. 3 will be subtracted from its x coordinate.
i.e. B'(1 - 3, 1)
B'(-2, 1)
<em>When we plot the above point A', B' and C', we get the option D as correct.</em>
Answer:
Equation will be y = 5x + c
Step-by-step explanation:
For point (5, 1)
1 = 5(5) + c
Or, c = - 24
So, y = 5x - 24
Considering the given <em>information</em> in the question, the value of x is 
, and that of y is 
.
A <u>transversal</u> is a <em>line</em> that <em>cuts</em> through two given parallel lines. Thus it i<em>ntersects</em> each parallel line at a point, forming <u>four</u> angles each.
From the given <em>information</em> in the question, it can be <em>inferred</em> that:
the given<u> bottom</u> right angle of the first<em> intersection</em> and the bottom right angle with the <em>second intersection</em> are <u>congruent </u>(corresponding angle property).
So that,
= 
= 
- 
= 
............ 1
Also given that the top <em>right angle</em> at the<u> second</u> intersection is a <em>right </em>angle, then;
+ 
= 
(sum of angles on a straight line)
This implies that;
= -
=
So that,
y = 
y =
Thus substituting the value of y in equation 1, we have;
= ........ 1
= 8(7.5)
5x = 60
x = 
x =
Therefore, x = and y =

Answer:
215g for 40p is best value for money.
Step-by-step explanation:
215g/40p = 5.38 g/p
395g/74p = 5.33 g/p
It's a question of decimal division.
13 + 21 = 13- -21
The minus sign and negative cancel each other out.
