Given:

$5|x-3|+3>7$

Aim:

We need to find the value of x.

Explanation:

Subtract 3 from both sides of the equation.

$5|x-3|+3-3>7-3$

$5|x-3|>4$

Divide both sides of the equation by 5.

$\frac{5}{5}|x-3|>\frac{4}{5}$

$|x-3|>\frac{4}{5}$

Square both sides.

$(x-3)^2>(\frac{4}{5})^2$

$(x-3)^2>\frac{16}{25}$

$x^2-6x+9>\frac{16}{25}$

multiply

$x^2-6x+9>\frac{16}{25}$

Imagine that you are given two linear equations in slope-intercept form. You

Sholpan [36]

Answer:

C. infinitely many

Step-by-step explanation:

If two equations in slope-intercept form have the same slope and y-intercept they must be the same line. Additionally, the solutions of a system of equations are wherever the two lines intersect. Since the lines are the same they must intersect at every point. Therefore, there are infinitely many solutions.
