Ok first of all, I EXTREMELY appreciate your use of parenthesis. Ok so first just raise both sides to the power of 1/2.

(\frac{3}{8})^{x}=\frac{8}{11}

You'll see why I didn't include a negative. Then apply the log base 3/8 and you get

x =   log_{ \frac{3}{8} }( \frac{8}{11} )
Then you split the log up and you get
x =  log_{ \frac{3}{8} }(8)  -  log_{ \frac{3}{8} }(11)
You couldn't put a negative value for a log. That is why I excluded the negative part of the sqrt.

What is the value of the discriminant of the quadratic equation −1 = 5x2 −2x, and what does its value mean about the number of r
Zepler [3.9K]
For the equation:
-1=5 x^2 - 2 x
5 x^2 - 2 x + 1 = 0,           then we substitute: a=5,  b=-2,  c =1
to discriminant formula: D= b^2 - 4 a c = (-2)^2 - 4 * 5 * 1 = 4 - 20 = - 16
Answer:
The discriminant is equal to -16 which means the equation has no real number solutions.

Kenny bought a new car stereo that cost $220, but he had a coupon for a 14% discount. How much did Kenny pay for the car stereo.
jok3333 [9.3K]

Answer:

189,2$

Step-by-step explanation:

220*0,86=189,2

14% = 14/100 = 0,14

1-0,14 = 0,86

price* factor between 0 and 1, 0 -> item is free, 1 -> full price
