Use the equation of the water level of the river represented by the equation y=-4x + 170, where x represents the
vovangra [49]

Answer:

(0,170)  and (60,-70) and (5, 150)

Step-by-step explanation:

To see if a given point is on the line or not, you just have to enter the x value (first value in the parenthesis) and see if the function returns the correct y value (second number in the parenthesis).

f(x) = -4x + 170

(170,0)  => -4 (170) + 170 = -680 + 170 = 510.  NO, not equal to 0.

(0,170) =>  -4 (0) + 170 = 0 + 170 = 170. YES

(12, 126)  => -4 (12) + 170= -48 + 170= 122. No, not equal to 126.

(50,30)  => -4(50) + 170 = -200 + 170 = 130. No, not equal to 30.

(5, 150)  => -4(5) + 170 = -20 + 170 = 150. YES

(60,-70) => -4(60) + 170 = -240 + 170 = -70.  YES

If 6^4x = 82, what is the value of x?<br> Round your answer to three places.
neonofarm [45]

Answer:

x=0.61485921

Step-by-step explanation:

The given equation is in exponential form:

6^{4x} =82

To find x we need to write it in logarithmic form:

b^{a} =n ⇒ log_{b} n=a

6^{4x} =82 ⇒ log_{ 6 }  82=4x

           2.45943684 = 4x

              \frac{2.45943684}{4} = x

           0.61485921 =x

To prove this, we can substitute the value into the given equation

             6^{4x} =82

6^{4(0.61485921)} =82

               82=82

Therefore, the answer is x=0.61485921
