Answer:
C
Step-by-step explanation:
to get to 18 from 15, you add three.
You keep adding three to every number for the y values since it it a linear function. The x values went up by 1 and the y values went up by 3.
A scale of 1:50 000 means that every centimetre on the map is equal to 50 000 centimetres (500 metres) in reality.
The distance between two towns on that map is 6cm, therefore in reality there’s 6 * 50 000 = 300 000 centimetres, which is equal to 3 000 metres, which is equal to 3 kilometres.
Answer:
<h2>( 2 , 1 )</h2>
Step-by-step explanation:
2x - 2y = 2
<u>5</u><u>x</u><u> </u><u>+</u><u> </u><u>2</u><u>y</u><u> </u><u>=</u><u> </u><u>1</u><u>2</u>
7x = 14
<h3>
x = 2</h3>
(2x - 2y = 2)-5
<u>(5x + 2y = 12)</u><u>2</u>
-10x + 10y = -10
<u> 10x + 4y = 24</u>
14y = 14
<h3>
y = 1</h3>
x = 2
y = 1
(2,1)
Answer:
x³-2x² = x2(x – 2) cubic units
Step-by-step explanation:
The volume of a prism is found by multiplying the base area by the height. The base area is a parallelogram and so the area is x*(x-2) = x² -2x.
Multiply this area by the height x.
V = x(x² - 2x) = x³-2x²
This is the same as x2(x – 2) cubic units.
