Answer:
the given <em>relation</em><em> </em><em>is</em><em> </em><em>function</em><em> </em><em>because</em><em> </em><em>all</em><em> </em><em>elements</em><em> </em><em>of</em><em> </em><em>domain</em><em> </em><em>is</em><em> </em><em>mapped</em><em> </em><em>with</em><em> </em><em>the</em><em> </em><em>elements</em><em> </em><em>of</em><em> </em><em>range</em><em> </em>
30, 34
You add 4 on
44
Because it starts at 10 and 10 cannot be divided by 4
The formula for Area of a circle is =
![\pi {r}^{2}](https://tex.z-dn.net/?f=%5Cpi%20%7Br%7D%5E%7B2%7D%20)
So, the radius will be half of diameter, which is 6÷2,
The radius is 3,
A = 3.14 × 3×3
= 3.14 × 9
= 28.274
Answer:
y = 4x + 5.5
Step-by-step explanation:
We put 2y in the y spot, obviously
2y = mx + b
Then we put 8x in the x spot
2y = 8x + b
Then we put 11 in the b spot
2y = 8x + 11
Then, to simplify, we divided by equation by two (it still gives the same results)
y = 4x + 5.5
The use of grouping symbols in math shows us which part of the problem or expression should be done first. Brackets, braces and parentheses are common grouping symbols used in mathematics. If no symbol is shown between brackets, forexample, (3+7)(8+1) it means that you should multiply after simplifying the operations inside the brackets.
