WILL MAKE BRAINLIEST!! On a math test, Jun was asked to find the point(s) where the equations y = x2 + 10x – 6 & y = 7x – 2 intersect. Jun’s solution is shown below.Jun’s solution:y = x2 + 10x – 6y = 7x – 2x2 + 10x – 6 = 7x – 2 x2 + 3x – 4 = 0(x – 1) (x + 4) = 0x = 1 or x = -4The graphs intersect at (-4, 0) and (1, 0)a) Is Jun’s solution correct? Explain why or why not.b) If Jun’s solution is incorrect, show the correct work for this problem.Answer:

The decibel level of sound is 50 dB greater on a busy street than in a quiet room where the intensity of sound is 10^-10 watt/m2. The level of sound in the quiet room is (10,20,100) dB, and the intensity of sound in the busy street is (10^-1, 10^-5, 10^-10) watt/m2. Use the formula , β = 10log I/I 0 where β is the sound level in decibels, I is the intensity of sound you are measuring, and Io is the smallest sound intensity that can be heard by the human ear (roughly equal to 1 x 10^-12 watts/m2).
