Which of the following are solutions to the equation below?

Mathematics
1 answer:
anastassius [24]3 years ago
4 0

Answer:

C and F

Step-by-step explanation:

Given

(3x - 5)² = 19 ( take the square root of both sides )

3x - 5 = ± \sqrt{19} ← note plus or minus

Add 5 to both sides

3x = ± \sqrt{19} + 5 ( divide both sides by 3 )

x = ±\frac{\sqrt{\sqrt{19}+5 } }{3}

Separating the solutions

x = \frac{\sqrt{19}+5 }{3} → C

x = \frac{-\sqrt{19}+5 }{3} → F

A line passes through the points (3,5) and (2,0) what is the slope of the line?
Veronika [31]

Answer:

5

Step-by-step explanation:

slope = (difference in y)/(difference in x)

subtract the y-coordinates: 5 - 0 = 5

subtract the x-coordinates in the same order: 3 - 2 = 1

Divide the difference in y by the difference in x.

slope = 5/1 = 5
