7 0

Step-by-step explanation:

65 + (y + 9) = 180 ---------- Sum of angles on a

straight line

y + 65 + 9 = 180

y + 74 = 180

y = 180 - 74 = 106

6x + 7 = y + 9 ----------- Alternate angles

But y = 106,

6x + 7 = 106 + 9

6x = 115 - 7

x = 108/6 = 18

$\cosh x=\dfrac{e^x+e^{-x}}2$

So

$\cosh(\ln 5)=\dfrac{e^{\ln5}+e^{-\ln5}}2=\dfrac{5+\frac15}2=\dfrac{13}5$

The function T(h) = -15 + 3h represents the outside temperature (in degrees Fahrenheit) of Unalakleet, Alaska, where h represent

vodka [1.7K]

Since 3:00 a.m is three hours after midnight, the variable h in the function would be three.

T(h) = -15 + 3h step 1 - write the equation
T(3) = -15 + 3(3) step 2 - plug in h, which is three
T(3) = -15 + 9 step 3 - simplify the expression
T(3) = -6
