Answer:
see explanation
Step-by-step explanation:
Given
(a)
3x + 2y - 8 = 0 ( subtract 3x - 8 from both sides )
2y = - 3x + 8 ( divide the terms by 2 )
y = - x + 4
(b)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x + 4 ← is in slope- intercept form
with slope ( gradient) m = - and
(c)
c = 4
That is crosses the y- axis at (0, 4 )
To solve this for c, you need to use the Law of Sines which is SinA/a=SinB/b=SinC/c. So, your equation would be Sin39/15=Sin79/c. To solve this you would do the fish method. So first, you multiply sin79 x 15. Then you would divide the answer of that by sin(39) which = c
c= 23.4

Answer:
16
Step-by-step explanation:
mult by root three and root 2
2 root 3 turns into 6
5 root 2 turns into 10

Question:
evaluate (100+650)-(2 ÷ 300)
Answer:
<em>749.99333333333</em>
Step-by-step explanation:
- The acronyms for order of operations mean <u><em>you should solve equations in this order always working left to right in your equation</em></u>.
- PEMDAS stands for<u> "Parentheses, Exponents, Multiplication and Division, Addition and Subtraction"</u>
- <em>You may also see BEDMAS, BODMAS, and GEMDAS as order of operations acronyms. In these acronyms, "brackets" are the same as parentheses, and "order" is the same as exponents. For GEMDAS, "grouping" is like parentheses or brackets.</em>

<h2><em>Solve Equation</em></h2>
<em>Input Equation:</em>
<em />
<em>(</em><em>100+650)-(2/300) = (750)-(2/300)</em>
<em></em>
<em>= 750 - (0.0066666666666667)</em>
<em></em>
<em>= 750 - 0.0066666666666667</em>
