X+4y=6<br> 3x+3y=9<br> Answer is 6.3 but how

maksim [4K]

Answer:

X = 2

Y = 1

Step-by-step explanation:

x + 4y = 6

3x + 3y = 9

3x + 12y = 18

3x + 3y = 9

9y = 9

x + 4y = 6

y = 1

x + 4 * 1 = 6

y = 1

x + 4 = 6

y = 1

x = 2

so there ia only 1 solution for this equation is (2;1)

Done :))

Let fx) = 8x - 3<br> What is f(5)?

mihalych1998 [28]

f(5) means to replace the x in the equation with 5.

f(5) = 8(5) - 3

f(5) = 40 - 3

f(5) = 37

Use the Law of Sines to find the measure of angle J to the nearest degree.

rjkz [21]

$\bf \textit{Law of sines}
\\ \quad \\
\cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c}\\\\
-----------------------------\\\\
\cfrac{sin(J)}{9.1}=\cfrac{sin(97^o)}{11}\implies sin(J)=\cfrac{9.1\cdot sin(97^o)}{11}
\\\\\\
\textit{now taking }sin^{-1}\textit{ to both sides}
\\\\\\
sin^{-1}\left[ sin(J) \right]=sin^{-1}\left( \cfrac{9.1\cdot sin(97^o)}{11} \right)
\\\\\\
\measuredangle J=sin^{-1}\left( \cfrac{9.1\cdot sin(97^o)}{11} \right)$
