Answer:

y=7x-47

Step-by-step explanation:

$(8, 9) = (x_1,y_1) \\ m = 7 \\ y - y_1 = m(x - x _1) \\ y - 9 = 7(x - 8)$

$y - 9 = 7x - 56 \\ y = 7x - 56 + 9 \\ y = 7x - 47$

Neat
of turf, 83.33333% of the 1050 were minor
so about 875 minor injuries in turf
and 10.857% of 1050 were substantial meaning about 114 substantial
leaving 63 severe field turf

meaning 938 minor in gras (totalminior-minorturf=grassminor)
so now we know that grassmionr=938 that that is 1
and hen that is 77.972 gras is mionr so 938=77.972%
1203 total gras
then 4.26 of gras is severe or about 51
and leaving about 217 substantial gras injuries
total them yourself

Answer/Step-by-step explanation:

Part A:

$Key:\left[1 Adult = 4 Student]$

$Formula: Divide$ $by$ $4$

12 Student = 3 Adult

24 Student = 6 Adult

40 Student = 10 Adult

Part B:

33 Student

Hence, divide 33 by 4 = 8 with a remainder of 1.

Therefore, 8 Adult and for the remainder 1 student either one Adult takes 5 Student or Needed 9 Adult.

Solve log 3x -log 13=2. Round to the nearest thousandth if necessary.

Vikentia [17]

$\bf \textit{Logarithm of rationals}\\\\
log_a\left( \frac{x}{y}\right)\implies log_a(x)-log_a(y)
\\\\\\
\textit{Logarithm Cancellation Rules}\\\\
log_a a^x= x\qquad \qquad \boxed{a^{log_ax}=x}\\\\
-------------------------------\\\\
log(3x)-log(13)=2\implies log_{10}(3x)-log_{10}(13)=2
\\\\\\
log_{10}\left( \frac{3x}{13} \right)=2\implies 10^{log_{10}\left( \frac{3x}{13} \right)}=10^2\implies \cfrac{3x}{13}=2
\\\\\\
3x=26\implies x=\cfrac{26}{3}\implies x=8\frac{2}{3}$
