Note that when adding logs of the same base you multiply the insides of the log. Therefore:
㏒8(2)+log8(4x²)=log8(8x²)
log8(8x²)=1
8=8x²
x=√1, x=1,x=-1

Identify the x-intercept and y-intercept of the line 2x−5y=202x−5y=20.

tensa zangetsu [6.8K]

   2x - 5y = 20

At the x-intercept, y=0 .

   2x = 20 ==> x = 10

At the y-intercept, x=0.

   -5y = 20 ==> y = -4

At 106°F, a certain insect chirps at a rate of 67 times per minute, and at 108°F, they chirp 83 times per minute. Write an equat

Step2247 [10]

Answer:

$y=8x-781$

Here, $x$ represents temperature and $y$ denotes rate of chirping per minute.

Step-by-step explanation:

Let $x$ represents temperature and $y$ denotes rate of chirping per minute.

At $106$ °F, a certain insect chirps at a rate of $67$ times per minute.

Take $(x_1,y_1)=(106,67)$

At $108$ °F, they chirp $83$ times per minute.

Take $(x_2,y_2)=(108,83)$

Slope intercept form:

$y-y_1=(\frac{y_2-y_1}{x_2-x_1})(x-x_1)$

$y-67=(\frac{83-67}{108-106})(x-106)\\\\y-67=(\frac{83-67}{108-106})(x-106)\\\\y-67=(\frac{16}{2})(x-106)\\\\y-67=8(x-106)\\y-67=8x-848\\y=8x+67-848\\y=8x-781$
