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

which equation is represented by the function table below?          x's are 1,2,3,4              y's are 8,14,20,26     
Reika [66]
F: R -> R, f(x) = ax + b;
f(1) = 8 => a + b = 8;
f(2) = 14 => 2a + b = 14 => a = 6 and b =2;
f(3) = 20 => 6*3 + 2 = 20 True;
f(4) = 26 => 4*6 + 2 = 26 True;

then, f:R -> R, f(x) = 6x + 2;
