Answer:

C.) Square both sides twice and then solve the resulting linear equation.

Step-by-step explanation:

We are given a equation:

$\sqrt{3x+4}=\sqrt{3x}+4$

On squaring both sides, we get

$3x+4=3x+16+8\sqrt{3x}$

= $8\sqrt{3x}=-12$

again on squaring, we get

$64\times 3x=144$

⇒ x=3\4

Hence, solving this equation required Squaring both sides twice and then solving the linear equation

Hence, Correct option is:

C.) Square both sides twice and then solve the resulting linear equation.

Function 1: y = 4x + 5 Function 2: The line passing through the points (1, 6) and (3, 10). Which of these functions has the grea

Gwar [14]

Answer:

Step-by-step explanation:

function 1 : y = 4x + 5

In y = mx + b form, which is what ur equation is in, the slope can be found in the m position. So the slope of this function is 4.

function 2 : (1,6),(3,10)

slope = (y2 - y1) / (x2 - x1)

(1,6)...x1 = 1 and y1 = 6

(3,10)...x2 = 3 and y2 = 10

now we sub

slope = (10 - 6) / (3 - 1) = 4/2 = 2

B. Function 1, because the slope is 4 and the slope of function 2 is 2. <==

What is the solution to the inequality x(x - 3) > 0?

Nimfa-mama [501]

Answer:

D) x<0 or x>3

Step-by-step explanation:

x(x-3)>0

either x>0 and x-3>0 .... positive-positive=positive so x>3

or x<0 and x-3<0 ..... negative-negative=positive so x<0

if x=0 then x(x-3)=0

Try this option ↓

Step-by-step explanation:

1) according to the condition two angles are equal, then two sides are equal also, it means

2) √x+4=√(5x+4);

3) the 'x' can be calculated if to solve this equation:

$\sqrt{x} +4=\sqrt{5x+4}$ ;

$x+16+8\sqrt{x} =5x+4;$

$4x-12=8\sqrt{x} ;\ => \ x-2\sqrt{x} -3=0;$

$\left \{ {{\sqrt{x} =-1} \atop {\sqrt{x} =3}} \right. \ => \ x=9.$

4) finally, answer: 9.
