Answer:
Step-by-step explanation:
A relation is said to be a function when each input value (x-value) show a distinct output value (y-value).
From the table attached,
For input value x = 0, there are multiple values of output values (y = -2, -1, 0, 1, -2).
Therefore, data given in the table doesn't represent a function.
5miles/8km = xmiles/80km
8x=400
x=50
You need three non-collinear points to name a plane.
Non-collinear means "not on the same straight line". So these three points can't all lie on the same straight line. If three points do lie on the same straight line, then it is impossible to generate a single unique plane.
FACTORISATION IS BASICALLY FINDING LIKE-TERMS.
1. FIND THE HCF OF 8. HERE, THE HCF IS 8. ALSO, CHECK ALL THE LIKE-TERMS. LIKE-TERMS ARE OUTSIDE THE BRACKET AND UNLIKE TERMS ARE INSIDE.
2. ADD THE TERMS IN THE BRACKET AND THE TERMS OUTSIDE THE BRACKET FROM STEP 1.
8x + 8y + rx + ry
1. 8 (x + y) + r (x + y)
2. (x +y) (8+r)
