Answer:
(x + y)1 - a)
Step-by-step explanation:
x + y - ax - ay
= x - ax + y - ay
= x(1 - a) + y(1 - a)
= (x + y)1 - a)
The area of a triangle can be determined as half the product of two sides multiplied by the sine of the angle between them. In this case,
A = (1/2)(AB)(AC)(sin A) = (1/2)(6)(15)(sin 48) = 33.44 square units.
Yes.
8 + 1 + 1 = 10, so there are 10 parts to the ratio.
3.5 litres divided by 10 would mean that each part of the ratio is worth 0.35 litres.
The colour is worth 8 parts of the ratio. 0.35 litres multiplied by 8 would give 2.8 litres, meaning 2.8 litres of colour are required.
Fiona has 2.9 litres of colour, which is more than enough to make 3.5 litres of paint mix.
Answer:
false
Step-by-step explanation:
Answer:
The new points to the triangle will be:
Step-by-step explanation:
Because the reflection point is at 
, all x values will subtract their distances from to get their new values. The y values remain the same.
The starting values are:
Point 
is 5 units away from , so we'll subtract 5 from -1 to get the new x value: 
, so 
.
Point 
is also 5 unit away from , so we'll subtract 5 from -1 to get the new x value: , so 
.
Point 
is 7 units away from , so we'll subtract 7 from -1 to get the new x value: 
, so 
.
