Hope this helps
Answer:
Step-by-step explanation:
<h3>Given </h3>
- Point (5, -7) and midpoint (15, 1)
<h3>To find</h3>
<h3>Solution</h3>
<u>Midpoint formula:</u>
- x = (x1 + x2)/2,
- y = (y1 + y2)/2
<u>Substituting values:</u>
- 15 = (5 + x2)/2 ⇒ 5 + x2 = 30 ⇒ x2 = 30 -5 ⇒ x2 = 25
- 1 = (-7 + y2)/2 ⇒ -7 + y2 = 2 ⇒ y2 = 2 - (-7) ⇒ y2 = 9
<u>Missing endpoint is:</u>
Factorisation is basically where you have to find everything in common between 2, 3 or 4 terms.
In factorization, you take out the like-terms. eg.
12x-6y
6(2x-y)
We have to find the HCF of 6 and 12 which is 6.
Here, the 6 is common (goes outside the bracket) and the other numbers (which are in the bracket) are uncommon.
Always remember in factorisation that:
+ and + = –
– and – = +
– and + = –
+ and – = –
They are supplementary angles.
